answered grow question 6y ago
Considering I don't see signs of it anywhere else.. i'm guessing the water pooled up and roasted the plant with your lights.. 👊

I have no idea what's happening here but the girls are showing some kind of deficiency. Browning, curling leaves. I have two 100w led lights above them and I use an organic dry fertilizer, I recently brewed a compost tea to try to get nutrients to them

Pest attack. What can I use to eradicate?
3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil? - The temperatures were very high here, exceeding 30°C, this week it will decrease. - I have other plants to harvest and I'm going to take advantage and clean the grow. Help 😥

Copper spots
I noticed these copper spots and leaf tips about a week ago, it doesn’t seem to be progressing too fast. The plants otherwise seem to be healthy but what is the issue? Magnesium Def?

Guess on what this is?
Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.

Why is my WW seedling browning?
I have a White Widow seedling that is showing brown spots. I am not sure if the LED light was too close, or if it is showing nutrient deficiencies/excesses. pH=5.8, PPM=160 (80ppm in well water).

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.
I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!

What am I looking at?
Redish Brown spots, and slight discoloration. Magnesium deficiency? Calcium? Other? Gave them a splash of Calmag, but was it even necessary? OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)
