Rusty brown spots on edges of leaves near top of the canopy
MediciGradestarted grow question 3 years ago
I'm not sure if this is nutrient burn or a cal/mag issue (deficiency or lockout), or something else. Anybody know what is likely to be causing this, and how to treat it?

I don't think it's a cal mag problem. It could be due to using up the potassium. I would be tempted to leave your nutes as is but increase the bloom slightly and see how that goes.

Bud rot? Mold?My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow).
I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :)
1. Is the "brown stuff" on the top bud "bud-rot"?
2. Are the "more intense white spots" mold?

Browning leavesMy leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.
