Nothing wrong with your plants, you don’t need to use an air stone in the standing water I just like oxygenating it. The key is to stabilize the fluctuations before subjecting the plant to it. With the air stones it also keeps a current going so getting accurate reading of levels is easier. It’s gonna be a bit rough for your first couple but if you have patience and pay attention you will begin to be able to diagnose and solve these issues on the fly.

hijacking? you are giving me exactly what i need mate, i can't find this much accurate information with searching threads one by one, thank you!

- im going to post a reply so i can attach photo about timing of main lining, are my plants ready or not?

Timing of main lining

- Are my plants ready or not?

what do you guys think about it?

 

[FlyingDutchPaddy]

so it looks like it has 3 nodes (pair of leaves) now, working on the 4th.

if it were my plant, i'd clip the 1st set of leaves, and top it where it is now (assuming you can cut safely without damaging the new grow tips).
1st leaves i refer to are those at the same hight of the cotyledons.
clip that entirely, also the growth tips.

the other 2 pairs, i'd leave the fan leaves on so that your plant has 2 pairs of proper leaves.

looking at your pics, i'd snip where you have the bottom red lines, and the top.
leave the middle for now, that is if you want to quadline the plant.

There's a thread on quadlining here: https://forum.growweedeasy.com/forum/growing-community/287356-quadlining

if just mainlining, yes, snip all red lines carefully.

 

[maner]

1. You mean on the first level should i cut cotyledons and growth tips also?

2. At the top red line should i cut it of entirely from exactly that line? cause there is no growth tips under that line.

 

[FlyingDutchPaddy]

bottom yellow line - snip everything - to the stem.
middle - snip some from the leave stem.
top - maybe a little extra time so you can cut safely without damaging the growth tips.

that is, if you want to Quadline the plant.

Mainline, i'd follow the 2nd pic.

Week 4 (11.02.2019)

Weekly change of reservoir done, i have started to put 50ml ice bottle 2 times a day

water solution:
- 10ml pH down
- 20ml Flora trio (micro-gro-bloom)
- 5ml Great White Mic.

Final rates (30L):
- 5.5pH 593ppm (NaCl)
-RH: 40%
-Temperature: 22° C
-Reservoir Temperature: 20°C
-LED disctance: 71cm - 28"

Main Lining:
- Kilimanjaro topped and bottom, mid lines cleared. (pictures attached)
- BBSC bottom and mid lines cleared, not topped yet.

Questions:
- Roots are growing so fast, colours in the begining of the roots are seems brownish but rest of them which stays in water solution look so health with snow white colour. what are your thoughts?

- im going to use main lining low stress training as you can see, i wonder how much time is it going to add to vegetative stage if i make it 3 times (to reach 8 main colas cause my both strains are sativa dominan or 100% sativa)

- if this will add weeks for each topping and lining, how should i arrange my nutrients dosage? (im following Sirius Fourside's trio schedule which sirius mentioned in "top fed dwc cannabis setup guide" as you can see im using 1/2 of flora trio nutrients +great white)

- there is no ready to use scrog net here, what should be the good height and width of the scrog net's squares. I found badminton net and fishnet with 2,5-3cm witdh squares, i think i can fit those to the tent, what do you think about it?

- I have read something about great white and it says that if you are using great white and if you add starch to your solution, the micro organisms in great white absorbs starch and produces sugar which later used for plant food. What do you think? (https://fifthseasongardening.com/more-about-marvelous-microbes)


thanks

As far as your roots look, to me they look fine, here are some root shots. One is my mothers (Now flowering to close out year) and the other is two clones that are 52 days from cutting.

 

[LurkingInTheGrass]

yay!
looks like everything is starting to come together for you

roots:
some of the older roots, will be stained from the micro nutes
white is healthy and good, she is going to start making more roots for you

training:
it depends on the plant
some plants don't want to train the way you want so, they slow their growth
unless you have a tight timeline (auto-flowers) - you can veg as long (or as little) as you want/need

nutrients schedule:
check your nutrient line
mine says: for longer veg; repeat week 3 dosage, for longer flower; repeat week 8 dosage

great white and starches\sugars:
Soil growers do it, with unsulfured molasses
I haven't found anything like that for hydro, yet. I haven't been looking all that hard, just trying to get my grows consistent with base nutes before I start adding the expensive 'extras'

 

[SinsemillaScientist]

LurkingInTheGrass look at the sweet carbo line, its for hydro and comes with a lot of compellling research. (Not sure Im completely sold) Although it seems to be working for most users

Week 6

Hi guys my work has kept me busy on these last 2 weeks i couldn’t make a time to write notes of week 5 and now today m going to change the reservoir for week 6. In week 5 lot of things have happened, i made the second topping to make 4 main colas, but when i was bending i broke BBSC’s 2nd main stem, then i taped it with duct tape. On the following day of this injury, 1 of the symmetrically growing 2 fan leaves continued growing like nothing has happened but the other one seems dead (on the same stem’scracked side). I made second topping on that day (9 day after the first topping), it was a bit risky cause growth tips are not grown enough to avoid cutting them but i thought that it may help them to get better when getting all the energy and i waited 1 more day and dead side has nearly ressurected, it has resistance when i press the fan leaves’s stem a bit down and leaves seems alive when i touch and pat them carefully, now it already has growth tips 2-4 days away from 3rd topping.



Now my questions are:

- Should i cut old fan leaves on my second topping?

- is 9 days too long? Too short? Or is it on time?

- Do you suggest any methods for bending stems, im not sure that if i bended them too early or too late. I tried to be very careful and have bended them day-by-day even with my fingers before tying them.

- photos belong to 21.02.2019 minutes before second topping, but i only made topping and not removed any other fan leaves or anything

LurkingInTheGrass thanks for your infromative and encouriging reply, i couldnt get back to you but i read the post right away when you sent it, because its not that easy to reply from here.

 

[LurkingInTheGrass]

SinsemillaScientist my hydro store carries the Sweet line (a huge frigging wall of Botanicare products) everything from 'raw' to 'grape' Now I have to do some reading

 

[LurkingInTheGrass]

your roots are looking great

 

[LurkingInTheGrass]

hey maner

It is amazing how much damage we can do to them, and with a little extra care, they can recover from and even strengthen from

when it comes to topping and trimming - time is almost irrelevant, its a guide for us to do things, not the plant look at the plant - is she thriving enough? leaves up and facing the light? then she can take a topping or trimming

taking leaves is a bigger topic: there are no real hard and fast 'rules', more like philosophies

quick and dirty guideline to leaf defoliation: (in veg) try not to take more than 25% of your leaves

Week 7
-Third and final topping done
- Reservoir changed, ½ dosage of flora trio added, 5ml great white added
- I added the photos of the third topping and recovery of BBSC. I removed the duckt tape and everything seems fine for me, what do you think about it?

Questions:

• Im going to install scrog net this week, what should be the dimensions of the squares of the scrog net?
• My plants doesnt stretch much they are still so short what do you think about it
• Which fan leaves should i remove?
• When should i start transition dosage of flora trio?
• How long should i stay more in vegetative phase?

 

[maner]

My last questions still waiting for answers and here is my other questions:

-what do you think about the size of my tent? should i buy larger one? (my tent is 120x60x180 and my friend adviced me to buy 120x120x200 tent before i start to get the max efficiency)

-Im planning to install scrog net as i mentioned before and im not sure that should i buy ready to use scrog net or should i arrange square gaps myself. ready to use scrog net square size is 10cm but the scrog tutorial on LBH's famous scrog tutorial they said that square sizes are 2.5" which means 6.25cm does this difference affect much?)

- Im so curious that how im going to change reservoir when i install scrog net? is there any common method that i can use?

Bigger is always better, you can move things around easier and of course grow more. I can not speak to the efficiency side of the discussion.

"-Im planning to install scrog net as i mentioned before and im not sure that should i buy ready to use scrog net or should i arrange square gaps myself. ready to use scrog net square size is 10cm but the scrog tutorial on LBH's famous scrog tutorial they said that square sizes are 2.5" which means 6.25cm does this difference affect much?)"

I use 2 inch chicken wire as a reference, 6 inches seems to be a lot of vertical growth before you bend, or run it down the line. I can not really help you on this one, I have not used the large squares.

Currently I'm just using garden wire that I pull the limb down and attach to a wire I have running around the perimeter of my DWC Tank.

"- Im so curious that how im going to change reservoir when i install scrog net? is there any common method that i can use?"

I have a battery operated pump that I remove the nutrients, a small pond pump replaces the fresh. My DWC tanks are mounted on 3/4 plywood that has 3 inch casters below, I just unzip the front of my grow space and roll it out for trimming or replacement nutrients. I have a very tall space so no big deal, just not a lot of floor space.

Hey maner

-changing reservoir after installing scrog net
I went back your top post - you have 2 ports in your DWC (for 2 netpots). you will need to add another port and fashion a lid for it (just a plate will do, something heavy enough to 'seal' the hole from light)

like Rag mentions - a battery operated pump
This is the one I use: https://www.amazon.ca/OEMTOOLS-Tool...transfer+pump&qid=1552146360&s=gateway&sr=8-5

-Veg and Transition
Vegetation stage: you are allowing the plant to establish itself - and build a nice little foundation, to support and supply the plant through its life.
Transition: you are allowing the plant to come to terms with her internal changes, as she starts to flower

a plant that has light training (topped twice and LST) you Veg until you are 1/3 or 1/2 the size your space can support, flip lights to 12/12.
(In this situation, I continue to run Veg nutes for a week or so - until I see pistils, then switch to Transition nutes for another week or so, then switch to Flower nutes.)

scrog is a different schedule
you are vegging to fill the screen (so expect a slightly longer veg than normal)
once the screen is almost full (70-75%) you think about flipping to 12/12 (same protocol with nutes)

 

[LurkingInTheGrass]

not 'stretching' much (growing)

what are you Temperatures and RH?
If your ambient RH is low - you need to bring your temperatures down
if your ambient RH is high - you can allow a higher room temperature

look into Vapor Pressure Deficit (VPD)
you don't have to read deeply into it (gets to be a sciencey rabbit hole) - there are charts to assist you. you are comparing Temp to RH and finding the sweet spot for your plants to transpire (breath and sweat) in their specific state (early veg, late veg, early flower, late flower)
My RH is fairly static (low) so, I try to keep my grow room as cool as I can
