      -12 hours later, after the reservoir change i checked the pH and it was 7.90 (at 12.30 pm). 7ml pH down added to a little RO water mixed and added to reservoir, new pH was 6.49, 674PPM

      -checked ph again at 8.30pm it was: pH 7.10 , 3ml pH down added to a little RO water mixed and added to reservoir, new pH was 6.11, 680PPM

      is this much fluctation normal? i just changed the reservoir water yesterday cleaned every tube and nearly everything.

      - Are my roots ok?

        I use regular tap water and I don't get that much movement. I think my tap water is very good the PPM is about 170 the PH is 7.0. In my dwc setup 1 ml of ph down per gallon drops 1 point. Your roots look great !!

          Guys i have some questions and one of them is important because one of my plant (Big Buddha Silver Cheese) has some reactions on it's leaves, i haven't figured out against what and i need your help.

          - Im sending pictures of BBSC's leaves hope we can understand what it is there is also a little hole on the leaf you can see that in the picture which i put my finger backside of it, i also attached the Kilimanjaro as last picture

          - havent figured out why i still have pH fluctations yet but after 2 interventions of taking pH to desired levels reservoir water's pH nearly stabilizes, i use min 2 different water sources while im preparing solution, because my water purifier gives me high ppm levels, can it be the reason?

          - Height of my plants are still 2-3" is this normal?

            I was having huge ph fluctuations in my first month as well. I think it may have been the tote being new because after about a month it slowed down quite a bit. Now it seems that i will change out the res with solution ph'd to 5.5, after a night it'll usually have raised by about 1, I'll ph it back down to around 5.7ish and then it'll usually settle in around 6.2 for the rest of the week. I also had some small dead looking spots on the first couple nodes leaves, not sure what the deal was but the newer leaves that came in were fine after that.

            I think i went through a 1/3 of a bottle of ph down in the first month alone. Now i usually use about 3 capfulls between the initial PHing of the solution and adjusting after each res change. (I usually change every week, 15 gallons of water)

          i've seen similar fluctuations with pH, in that when i change the water i bring it down to 5.8 ish.
          couple of days later it was up near 7.0.

          added extra pH down and seems stable at 6.1 (last 2 days)

          im using pH down from GH now.... supposedly made with "food grade" acids.
          before i had pH down from Essentials, and that was much more stable imo.

            my pH down is home made which a store here made it and there is no brand, can that cause fluctations also?
            it stabilizes after 2 interventions in first 1-2 days.

            - do you think those colour fluctations and hole on leaves because of pH fluctations?

            - im in the middle of the 3rd week, what do you think about the growth of my plants? are they on track or not grown enough compared to 3rd week plant?

            i don't know how much of a difference home-made pH down would be compared to that what you can buy 'branded'.
            Seems that most of the commercial pH down solutions are "food grade" phosphoric acids (the Essentials one is 81%).

            Reading up online would suggest that 'extreme' fluctuations or sudden changes of pH are associated with the need to change the water, or at least, new nutrients are needed.

            color fluctuations & hole in leaves
            - quite possible, but I can't say for certain.

          It may help you to have some water set aside with an air stone in it for a day or two before you add to res. Balance and stabilize levels before doing your weekly res change. This will prevent the plant from suffering major ph swings(leaf spots) hope this helps

          ps I find even an hour or two does the trick

            i have antoher box for reservoir so i prepare my new water solution it. it wont be an issue to keep airstone in it for 1 day but i dont have extra airpump and im confused a bit, its not enough to keep airstone in water right? i also should turn on another airpump and connect the airstone to that?

            - do you think those reactions because of pH fluctations, and that little hole?

            - im in the middle of the 3rd week, what do you think about the growth of my plants? are they on track or not grown enough compared to 3rd week plant?

            Perhaps when I commented about my water I should have mentioned that I keep several 1 gallon milk jugs on the floor all the time. It lets it get stable I think.

            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.

          Maner, sorry for 'hijacking' your grow thread with pictures of mine, but its to indicate potential growth rates as asked.

          1st is 2 days after transplant,
          2nd is 1 week after,
          3rd is 2 wks after,
          4th is almost 3 wks in,
          5th is 4 wks + 3 days.

          average temp : 14C - 18C
          RH: 50 - 70 %

          as an additional FYI, I have my lights on constantly since planting into the pebbles.

            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?

            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...356-quadlining

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

            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.

          #24
          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/mor...elous-microbes)


            thanks

              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'

              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

            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.
