Help with some Diagnostics.

Not sure, but here's what I've been thinking the issues are with my 6 1/2 week old baby.

I'm using a ebb n flow table. 2'x4' with 4 SSH ladies. So far everything seems fine as in new growth of strong leaves etc, but the issues have not seem to worked themselves out quite yet with other leaves. I'm becoming concerned with the droopy leaves and the "cupping" they seem to being doing. I water 15min every 6hrs at 400ppm, with 18/6hr light.

(just changed to 24hr 15min every 4hr and 600 ppm, today)

My thoughts are that they are either being under watered, which would seem odd. Or overfertization.

all feedback welcome, thanks.

Do you smoke around your plants?where those burns are is where the plant breaths in co2 do you have fresh air coming in?

No I do not smoke in my growroom. Are you suggesting that I provide more CO2? I am not providing CO2 currently.

judging by the two pics I would go with overfert over underwatering for sure. the plant is an overall very dark green instead of the lighter healthier happy color. those leaf edges could be nute burn or a calcium deficiency, hard to tell with those pics.
have you flushed the res in the past 2 weeks, is the actual rockwool cube if u r using one, getting wet?, do you use tap or distilled/RO water?

I had afriend who used to smoke in his room when he did work in it and his plants looked very simular to how yours look after he stoped his plants started to look better. O.k. so you dont smoke then it nutriant burn for sure smokey the bandit said some good stuff clean your resivor flush your plants kepp your ppm around 600 for the young ones which you do.And how much air are you bringing into your system? What kind of nutriants do you use?

ya i wouldnt wanna smoke in my grow room. to much air flow to smoke. not to mention the lights are to bright for my "high" eyes.

ok, gotcha. ill give um flush and re run the nutes at 600, and go from there.

at the moment I am running floragro for nutes. As far as air I'm ducting from the main a/c unit of the house, with a 6" inline fan always on (its about 10ft of ducting pipe away from the exit point). and for air for the water solution is 2 12" stones all the time and 2 more 12" stones on when the pumps turn on.
