I recently had to leave for work and the day I left I gave them plenty of water. I was gone for 7 days. When I got back they were wilted and very dry. I gave them 1/2 does of onenes 5-9-7 and 1/8 dose of natural bloom 0-10-0. The plants stood back up and had good look to them the next day. The day after 2 of them started having some problems with leaves yellowing and browning, I will post few pics of leaves on here. The others still doing good. The ones affected are The Afghan Kush Ryder and the B.Lee. Running on 400HPS with 20/4. keeping temp around 78, humidity is at 40%. There in 5 gal buckets filled with potting soil. Gave them straight water yesterday incase of nute burn, didnt seem to help. I use rain water half the time and tap water that has set out 36hr the rest. Any suggestions or diagnoses is appreciated.
