How are you checking the pH? Also distilled water has such a low ionic strength that often it WILL produce incorrect readings on meters that were designed for high I.S. nute solutions. Don't fix what ain't broke; your plnats look excellent.
The leaves were yellowing from hunger. It is time to start in a 1/4 strength grow fertilizer. Also, low leaves naturally yellow and drop when they are no longer needed, or if they are deeply shaded by fresh, thick growth.

Need help, first time grower Hello, been lurking for quite some time trying to learn as much as I can and I'm about a week into veg and ever since I put my Church plants in my grow box the leaves have been coming out curled and rough, is this normal or do I have a heat problem. Temps are about 82 during the day, I'm logging what the temps get overnight tonight so I'll have that info, plants are under a 600W MH. Thanks for any help! :) Rating: 5
