need some urgent advice !​

I grow femenized plants. There are starting there 6th week now and they don´t look great.
First some data:
The room is ruffly 130sf. I got 5x BloomStar 4x FlatBoard 3500K H One 480W (20 flatboards)and 2 niello 600wh. I got a little less than 200 plants.
I have a little drip arrigation system. I fertilize with canna coco a+b, rhizotonic, cannazym and canna boost. The pots are 1.2 gallons.
I had some problems from the beginning. My ph downner lost its power after a day or less. Meaning I set the ph of the tank to 5.8 and the next day it was back to 6.5. I figured out a little to late that my ph meter also was off.
So the plants got the wrong ph for a while in the beginning.
Than I had to flush out the ph 2 times. So, all the plants got quiet a load of water.
Due to all these promblems I kept them quiet some time in vegetation. Untill yesterday the ec of the feeding water was set to around 1700. Now I pushed it up to 1950.
Now all the plants seme quiet droopy for quiet some while now. I didn´t water them for 3 days because the coco was quiet moist. After watering them yesterday for the first time with 1950 ec they seme a little better, but still look quiet droopy. Also quiet some leafs are still brown. Some died off. Also the plants seem very small. They are all prety much below 8in. They have bin growing a little bit over the last day. The coco is still moist in the buttom.
I am not sure how to continue.
Could it be that the coco is too dense, so that the water doesnt drain good ennough?
Should I let the coco dry out more or directly give them more nutrition?
How much feeding should I give them with arrigation system?
Should I keep them even longer in vegetation or switch them to bloom?
Also the temperature is quiet different in the buttom of the pots, the buttom of the plants and the top of the plants. Where is it most important to keep the temperature right?
It never came to me that there are of course forums where I can ask all these questions. I am really happy that I found this site!!
I am looking forward for some advice and Thanx in advance!

What’s your relative humidity at? Also temps? How far away are your lights? I wouldn’t switch to bloom until you figure out your issues. You should keep your coco 90% saturated all the time. How many feed events do you have a day? Did you fix your ph problem in the res? Could possibly be from how you mix’s your nutrients in or what your using to bring ph down.

I kept the temps with a few exceptions between 66 and 80f.
humidity mostly between 55 and 65%.
lights r around 20 in away.
Fixed the ph problems. The ph of the mixture in the tank still needs to b adjusted before every feeding. the new ph downer aparently looses efficiancy in combination with the nutritions.
I give them 1 quiet short feeding a day untill now.
Would it make more sense to give them 2 or more? Or maybe just every 2 or 3 days.
Could they b droopy because of too little nutrition?
I mix all the nutrients ( canna coco a+b, rhizotonic, cannazym and canna boost) in a 80 gallon tank.
I use ph minus from plagron. Before that i used a cheaper noname one.

I’m not familiar with your nutrients but based on your ec you definitely shouldn’t be lacking nitrogen, I was gonna say it seems a little high. I have not gone over like 1.4 ec even in flower. But again I don’t know your nutrients well enough. Dose look like you may have early stages of magnesium deficiency, I would add some cal mag or Epson salt to your nutrients.

Also are you running an exhaust?

The ph of the runoff in coco does not matter, what matters is you have the correct Ph going in

I believe your plants are way over fertilized...cut that 1950 in half and get a watering schedule at a minimum 2x's per day to runoff...in 1gals you may need to water 3 to 4 times per day in flower...

Get your ec down, pH in line and a proper feed schedule and things should come right around...and don't let the coco dry out, some dry back is fine but not alot

all these deficiencies are from wrong pH & too much nutes...plant can't use what your giving them

Water more for sure. Your dirt looks hella dry.

(Forgot my password, so i had to make a new login...)
First of all: Thanx a lot !!! (2 all)
I have bin meassuring in ec, which is the double of ppm. So in ppm(us) I am at a little below 1000
I am using this feeding chart.
I translated it to ppm:

I get this right, that I should water them 2x per day untill the water runs off in the buttom(in bloom 3-4)?
Won´t that stop them from absorbing oxigen by overwatering?
PPM a little below 1000 should b fine?!

Thanx!

any idea why the nutrition water solution in the tank allways ups the ph after a while?
Yes, the term is called "high alkalinity." Water with high alkalinity can be pH'd to your target pH and then within a few hours or over night, rise back up out of range. Using filtered water can help you remove the excess carbonate that causes the pH to fluctuate but you'll likely have to add calcium and magnesium back to your water afterwards.

But its also fine to just adjust the ph before every watering?

You're not removing the carbonate salts if you simply adjust your pH prior to watering. In theory, those carbonate salts can change the natural pH of your media over the course of a grow. I'm not sure how likely that is to occur in coco since it's a pretty inert media, but I would keep it in the back of your mind if nothing else seems to work.

P.S. Your plants look water-logged and swollen ... like they are having trouble transpiring. If your plants cannot move moisture through it's tissue and release it into the air, it's not going to uptake nutrients. The plant sits and becomes stagnant. Roots begin to rot and you begin to see a whole bunch of deficiencies.

So how do I stop them from being water-logged and swolen ? Isn`t 2x watering till run-off, doing the exact opposite?
When I put the coco in the pots I stampted the pots a few times, so I imagine it is possible, that the coco is a little more compressed than it would b good.
Even when I didn´t give them water for a few days, the coco was still moist in the buttom.

Is there any perlite added to your coco mix? And yes, watering 2x till run-off is counter-productive until you work this through. If it were mine, I would transplant into a coco + perlite mix to allow better drainage. I'd also consider using a cheap carbon filter designed to reduce ppm from your source water since you're experiencing alkaline pH swings.

P.S. I'm a soil grower so to "really help" you, we need someone with coco/hydro experience to chime in.

Don’t grow I coco but I do in water and your ec is out of this world , imho.

my plants are a similar size and I just reached 380 ppm or .76ec

also quit pulverizing with the lights , it’s really amazing to see the rate they grow and stand up with less.

Enjoy and good luck

I added a little bit of perlite, but not at all a lot. To transplant would b a lot of work. small room. allmost 200 plants
