So these are my girls right here, well at least i'm hoping. There both around 5 -6 weeks old and have been vegging under a MH conversion bulb in a DWC system. The ph has been in between 5 - 6.5, and the humidity anywhere from 15- 35 %(15% during the day and 35% in the night) and the temp always 75 - 80+. This is also the third day I haven't fed them (when I normally feed the, every two days) since I noticed a little leaf discoloration. Also I noticed that the very first two leaves of the plants, turned totally yellow and soft (but it can be from some previous nute burn)

Here are the pics, if any one could give me any help or advice or what the leaf discoloration may be and if the problem could be nute burn, so If I should keep waiting to feed them and flush them or not, it would really be appreciated

Thanks for the advice. My deep water culture system has a 330 ppm and I dont think the issue is the light, but I'll raise it another couple of inches.

I'll deff start feeding them more though, any idea how often I should feed them? Because right now its been every two days and twice a day sounds like a little two much.

I feed mine twice a day
4 about 10 mins each time
Although I use rock wool
R urs just in pebbles ?
Or is there rock wool in there aswell
I ask because rock wool retains water
Clay pebbles don't remember that
I wouldn't worry 2 much aout the light
But there is a little heat stress
How close is it

The lights are 34 inches from the hydrobox, but one plant is 13 inches and the other is 10-11 inches tall. As for rock wool, I've never used them, the roots grew straight through the clay pebbles, but my roots are submerged into water (deep water culture system).

Sounds good just make sure
U have lots aeration in the res
2 prevent root rot
And yeah they prob very thirsty
Is it hps light ?
If so those pebbles r gonna dry out fast
And may well be cause of ur stunting

Inside the hydro box I have a 60 gal pump pumping into two air stones sitting directly below the two net pots so I hope that should be good enough to prevent any root rot. But I also keep them underneath a 400 w Metal Halide lamp, and I haven't noticed much stunting in growth, and since the roots are constantly submerged in water what would make them thirsty? Plus I water them twice to three time a day with distilled water, and keep a fan and wet towels in my closet to keep temp low and humidity up.
