hey there Catova, it maybe looks beautiful, but i'm sorry to say it's actually P deficiency, this you can see from the discoloration starting on the leafs . Just add a PK booster or a (diluted) banana peel tea if you're going natural. Hope this helps ! 🚀

Got 3 photos. 2 in the ground 1 in 7 gallon. On all 3 the fan leaves and older leaves turning yellow at a pretty rapid rate. Prob losing 15 leaves a week rn. Purp is deeper into budding and not so bad. But should I hit them with a dose of grow big to sort it out? Or no?

Yellow bright new growth New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?
