The bottom leaves have been dying off a lot for about a month now and showing what I think is a ph problem with the healthier leaves so i got the stuff to fix the water ph. Then three days ago when It was a bit warmer the top leaves started to get brown spots. The other plant in the tent has been doing really good the whole grow but i noticed some small brown spots where only on the side they are touching.

Lockout likely potassium deficiency for sure. Likely nutrient buildup or ratio in the media, ph etc. caused by watering practices or high inputs

This is my second time growing,First time in a tent. There clones about 80-90 days old and close to three feet tall in five gallon fabric pot. The soil is potting soil plus by Schultz I use normal tap water that I started to ph to 6-6.2 about a week ago I water twice when dry or about every two day or three days. I haven’t used any fertilizers because I did this as a school project to see how they would do with just watering. I use a 100 watts light from Mars hydro the plants are around half a foot away from it and I’m running out of space in the tent which is only 2x2x4. The temperature is around 60-70 degrees and the humidity stays around 60-80.
