Hi guys, I left for a month and left my plants at my buddies' place so he could take care of em. They suffered a lot of stress and were stunted there, and developed these rashes. I thought it was overwatering. the leaves lay low, and have their tips pointed down. the few new leaves that grew in the past 3 weeks (there was VERY little growth in the past three weeks) don't seem to point down, but my plants are growing extremely slowly. I thought it was overwatering, so I started watering them once every five days. Still no results. A few more rashes have showed. here are some pictures of them. I was wondering if anybody could help me. I have a few baby plants (2 weeks) under the same conditions and they are all fine. I was wondering if it was some kind of nute deficiency, but the last thing I wanted to do was give them ferts when they don't need them. any help would be nice, this shits pissin me off since I've never had issues of the sort before.
Looks almost like too much nutes from the tips of your leaves curling and burning up. The brown spots could be a calmag problem, mine got yellow and brown rust spots then I bought some MagiCal and it solved my problem. 1/4 tsp per gallon every other watering
