Absolutely nutrient burn related. I agree with high roller. Water only next few times then dial back on the nutes some.

My cookies kush girls be stressed. Transplant stress? Magnesium? Heat? Need bigger pot?
Transplanted into solos with FFHF 4 days ago. 24-0 with 25w light up until yesterday when I put them on 18-6 & into the tent for first time. When do you guys use general hydroponics trio and cal-mag when growing in Happy Frog under TS600 Mars Hydro LEDs? Girls be stressed :(

Lowest leaves turned yellow
After a very hot and sunny day (about 37°C) I noticed that the lowest leaves turned yellow. Is this a sign that I should use more Terra Bloom? If so, how much more should I use?

Fatal ovewatering? Will she survive?
Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start. Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?

Yellow spots on bottom leaves.
Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.
