Too much information what is my issue?

[biggysquals]

6 plants
2 630 cmh each with one 4K and one 3k bulb
Co2 At 1200 ppm
Temps 78-82
Nutes canna bio line
Botanicare silica blast
Camg+
Soil is hp pro mix
5 gallon grow bags

well, to begin with, you can run your temps close to ten degrees higher with co2.
those look both overwatered and overfed.
how strong are you feeding? how much, how often?
what are you ph'ing to?
are you letting them sit in their run off water? are you watering enough to get run off?

 

[biggysquals]

Feeding when needed (soil is dry and pot are light) feeding as recommended but on lower end bio Vega 8 ml per gal rhizotonic 8 mil per gal calmag 5 mil per gallon silica blast 10 ml per gal
Using compost tea once a week without nutes. Minimal to No run off. Ph is 6.6 I do have a a 2nd room feeding same and it is 100% healthy but slightly warmer temps

BiggyB,
Don't know why one room would be different then the other. Your dosages seem ok...at least the vega. But the compost tea might be too strong. Did you make it? Castings? Some of that stuff can contain lots of N. Just a thought.

PS Nute burn seems to be an issue of total pps of everything...even the Ca and Mg in the water. So you may not be able to figure out exactly what caused it.

Compost tea in a box. Mixed per instructions fed 3/4 gal per plant

I'd suggest dropping the tea on that plant and maybe even reduce the others a bit too while it recovers.

And you know what the rule is for following instructions. (even with compost tea) Always assume they are too strong.

getting a little run off at least every other watering would help, i think you're getting a lot of built up salts in your pots. i'd water the next time with just ph'ed water, then get at least ten % run off each time.

I’ll try that thanks

With the grow, the cal mag and tea I see tons of nitrogen

^^^^^

Think of feeding your plants as adding water with different coloured marbles in.
The plants eat some more than others at times. But every time you don't wash out the old water and marbles, a few stay behind and gets added to with the next feeding...
Even feeding only low concentrations, the number of marbles in the bucket grows steadily...

You didn't mention what pH you water at......make sure it's between 6.2-6.3. But to me, it looks like multiple issues. I'd say over watering because of the droop and the leave tips show over fertilization.
