Brown spots on leaves
RJS420started grow question 5y ago
Can anyone identify what this is? I discovered some green aphids yesterday but they're in small numbers so i figured that wouldnt be it, also sprayed with biological killer. A nutrition problem maybe? Too much or too little? Only affects bottom leaves so far.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?6y ago

Brown Spots on LeavesI've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Upward Curling Brown Leaves/Nutrient Lock Out?I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light.
Leaves are curling upward and browning. Not crumbling yet but look like they will be soon.
Both new and old growth is being effected.
Maybe the Mineralized Phosphate was too much.

2 out of 5 plants are showing signs of nutrient burn? Soil growHi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz.
Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.๐ฆ
