Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

Weird burn
Thought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?

Light burn?
I noticed the tips of the top leaves are becoming paler, even slightly yellow. Could this be light stress/burn? My LEDs were approx. 30 cm from the canopy, now moved them up 15 cm.

Fan leaves turning extremely yellow late flower
Hello. Day 61 of flower, Green Crack 2.0 by Humboldt seed organization. Soil based. All of a sudden all the fan leaves are turning yellow. Trichomes are clear, no exceptions. Is it from finishing or did I mess up watering/nutes in the last couple of weeks? Thanks in advance.

What's the problem?
Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?
