FIRST STAINS!? First grow, first problem. Look! Budporn included

[Dr.Moggs]

Hello again fellow growers.

I am doing my first hydrogrow and everything has been going really well, especially for being the first grow.

Right now I am in the middle of week 5 flower.

Equipment:
Two tents, 150×150
Mars pro II cree 256 light
360 L Rdwc with 22 5 Gal buckets.

Nutrients:
Gold label A
Gold label B
Ultra PK
Ultra MG
Ultra NK
Enzyme
And ofc some good old PH down.

Medium:
Gold Label Hydrocorn

Seed:
Green house seeds White Widow Feminized

I am growing in two separate tents but the RDWC flows thru them both.

I haven't used any techniques during veg and first 3 weeks of flower. ( I have learned what to do to prepare for better yields in my next grow(witch already are in week Three veg, I'll leave that out for now)

In Tent 1. I just have an soft supportnet to prevent the plants from spreading out to much
In Tent 2. I am using an SCRoG net. here everything is going really well. No problems what I can see.
In the second tent however i have some issues I hope to get some feedback on.

Issue 1.
I have posted a thread regarding this issue earlier but I'm not sure what to do, the plants differs much in height(If I even need to do anything?)
Issue 2.
FIRST STAINS !? So thru out the whole grow I haven't had any stains/nute/ph burns. I just found them on two of my plants, so I hope I can prevent the others from getting I'll.
Plant 1. The stains are mainly on the top leaves, the stains look like cupper.
Plant 2.
The stains are only on the lower leaves and look something like dried saltwater-stains. I also perceive these leaves as soft and "lifeloosing"

The weird thing is that I am growing all of them In the same hydroculture.
My PH was at 6.5
Watertemprature 22°
EC between 2000-2900 ( I believe my EC meter needs calibration, I have two and one of them showed 2000 and the other 2900)

So my first guess was to much nutrients.
The action I have taked today:
I poured out 50 l from the RDWC and replaced it with 50 l tap water to lower nutrient level.
I also ph:d down to 5.8-6.

For all of you who had the patience to read thru all this I'll soon reward you with some budporn.

As I wrote in the beginning it's going well and I can see buds forming everywhere, i also saw my first trichomes today. It was like the first time I saw porn, amazing, interesting, scary and beautiful at the same time. 😅

To be short:
Do I need to do anything about the height difference(I can see difference in the development of the the buds) ?
What are the cupperstains ?
What are the salty stains ?

Last question, I found a branch that broke a few days ago.
When I found it I taped it and gave it support. Will this heal or should I cut it of ?

[Edit 1.] The order of the pictures dont correspond with the red thread in my thread. Hope you'll be fine anyways.

DAMN I LOVE GROWING

Hey Dr. Moggs,
great post and good growing!
stains look like the might be Ca deficiency. However, if it is only on older leaves that wouldn’t fit. Are the leaves with issues getting plenty of light or are they shaded out?
id recommend using training to control the height difference. That, or just raise the short one up on something. You want them both the right distance from the lights.

The branch should heal if you keep air off the wound. I recommend wrapping it with a thin strip of plastic wrap from the kitchen and getting grafting tape for future injuries.

Hope i addressed it all. Feel free to follow up!

 

[fwril]

The broken limb should be fine, keep it taped up for 2 weeks and the check and see if the plant has healed the wound. If not just re tape and check again in 2 more weeks.

The hieight issue is really up to you. You can bend the taller stalks down gently and secure them with plant ties or something of that nature. You don't want to do much else once the plant is into flower. The main reason is you want a even canopy so you can maxamize your light source. If you have a big height difference then you have one plant getting optimal light and another too low getting less out of the light. Or you risk burning your taller plant if you bring it down to the lower light. I personally would try to bend down the taller plant and tie it down.

The other issues idk. Really hard to tell from pictures due to the led light can you get a picture in a more natural light source? With LEDs off

 

[Dr.Moggs]

Hey and thanks for your input. The plant with the cupperstains only have the stains on the top leaves. They are getting slot of light but from a bit far away.

The salty stains on the other plant is only on the leaves at the bottom of the plants.

What kind of training are you suggesting ? From the research I have done, the information I find says that training it now will stress the plant and that that's a bad idea this late in bloom.
I can't move my plant up, it's not possible to move the plants at all due to the design of my RDWC.

I'll try to heal the branch

 

[Campesino]

Ok, the “cupper stains” are likely Ca deficiency then. I recommend adding Cal Mag (be aware of impact on EC/PPM).
Would need a better picture to diagnose “salty stains”

I would still supercrop the plant, but I understand your hesitation if you don’t have experience. It is pretty late, but I think it can be done without harming the plant in any way. Should really be done during the stretch though. At this point it may not be possible to achieve a fully even canopy.

 

[Dr.Moggs]

Hey !
Thanks for your feedback.
I'll post some pics without the LED light Tomorrow.

Since You and Campesino both Suggest i train my plants I will give them a workout tomorrow.

 

[Dr.Moggs]

I will give my plants a workout tomorrow , I dont need to get them all even but it would be nice to reduce the difference with at least 30 cm.

Regarding the stains I will upload better pictures tomorrow. I'll try to find some cal-mag.
Reccomend any brand ? I am a bit afraid to mix another nutrient brand with the one I have.

Will get a new EC meter tomorrow and give you and exact update on the levels.

Just to be curious, how long would you say they have left? I am guessing that I will be able to start flush in about 2-3 weeks? What do you think ?

 

[Campesino]

Yes try to match brands. I use GH CaliMagic.
Harvest looks several weeks away. How do you plan to run your final flush?

 

[Dr.Moggs]

All my nutrients is from the same brand, Gold Label. it is suposed to be a complete setup. Maby I can raise the amount of ultra PK to solve this.
Ultra PK: "promotes availability of Ca, Mg and trace elements"
Sounds like its almost the same..

Regarding flushing I was thinking about starting when about 40- 50%of my trichomes have become cloudy.
I will flush for 5-7 days and with 3-4 water-changes.
Is that a good plan ?

 

[Campesino]

Yes that seems to be the same. I will look it up at home. Have you been giving that already? Makes diagnosis less likely.
RE flushing. I am in coco and flush over just 3-4 days using florakleen. In hydro you can flush in 1-3 days with a flushing agent. This allows you to feed right until the end and don’t have to start flush until they are ready to harvest.

 

[Dr.Moggs]

@campesinos
I'll read more about these products, I have seen other reccomend different flushing agents.

I have a quick theory regarding the cupperstains. I spray my plants with batterywater every day, I dont really know why I do this but it feels like I give some extra love to my plants. Should I continue with this ?
My theory was that burns comes from water on the leaf plus the intense light from my LED lights.

 

[Campesino]

Battery water?
Yes, I would stop doing that

 

[Dr.Moggs]

Batterywater is demineralised and deionized water if You didn't know. Its not any kind of battery acid.
It sound kind of stupid with that name "batterwater". But knowing what it is I thought it sounded as an good idea.
My idea was to synthesize rain and mist by spray them with a mistnozzle
You dont spray your plants with water ?

 

[Campesino]

I don't as a regular practice, no. Many growers foliar feed with certain nutrients, but the purpose is giving nutrition not just water. I rarely foliar feed because I don't like water sitting on leaves.
Water on plants should be removed because it encourages mold and rot. Outdoor growers often try to cover or dry their plants during/after rain! You don't need to simulate rain, in fact, you want to avoid it!

 

[Dr.Moggs]

Good thing i joined This forum.
I'll stop that right away😅
Good constructive criticism, thanks Campesino

 

[Campesino]

No problem Dr.Moggs
This very well may be responsible for the stains, so let's see if they stop appearing. (old stains probably won't recover, just watch for new)

 

[Dr.Moggs]

Update 1. Middle of week 5 flower.
Stains on plant.

Here comes the pictures of my leaves without LED light.

I only detect stains on this 2 of my 22 plants.

Plant 1. This plant are having most stains, mainly on the lightexposed leaves.

Plant 2. Only showing stains on a few lower leaves. These leaves are getting very little light.

 

[9fingerleafs]

i often spray water on my plants and when they need it i put a 8x dose of calmag and they seem to love it

 

[Dr.Moggs]

This just got interesting.🤔
I Will give them a CalMag shower as you suggest 9fingerleafs and than no more showers for a few days. Depending on how they respond I will continue with this, I'll also boost my waterculture with some extra CalMag.

Seems like this can be the issue for the stains aswell. Or maby it's a combination, to little cal-mag in the water and absolutely nothing in the spray.

 

[9fingerleafs]

wait wait wait... ph 6.5?? thats way too high for hydro, that must be the main issue. different plants different symptoms

btw dont cut that branch off, it will be fine
