How close is your light and what are your room temps?

 

[pack21]

distants from lights is 2ft plus would you think it was nutrient burn or a ddefisisency cheers room temp is 76

If in doubt flush it out.

I see hydroton there and presume you have a rockwool cube to?

Flush with PH adjusted RO (if possible) water with a dose of epsom salts.

Take pictures with your lights off and a normal room light on.


Sooooo many people post pics like you have and we cant see what the plant is telling us.

yeah what hippy said. I can't see the problem with the yellow glow.

I use this cheap little pH and hydration tester you stick in the soil I got from Home Depot for just under 20 bucks. I'd use that, stick it in the soil and test the pH level.

I agree about the lights, first thing I thought.

5.8 is fine for hydro...hmmm...what is your ppm reading? Have you added nutes? When? How much?
