Check the PH on your runoff. Looks like she might be having a nutrient lockout. If the pH is fine try supplementing some cal mag in. 🤘😤

Fast yellowing in older and middle leaves, small buds.
Hi guys, I need your help on this one, this is a completely organic grow under a FC-6500 light which is 60cm at 100% power, it can't be light stress because the tops are fine.This yellowing happened fast in the span of 4 days.PH shouldn't be an issue since I calibrate regurarly.

problems with clones!
Friends, tell me what's wrong with the plant! I don't understand it's under-feeding or over-feeding! At first I thought it was a cal-mag deficiency, then I saw a purple stem and thought it was a phosphorus deficiency! Now I don't know what it is anymore! at the very beginning it

Leaf tips yellowing. Overwatering? Or nute burn?
I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Is this a CalMag deficiency?
It started with White Widow a few days ago, showing signs of yellow leaf tips. I'm quite sure I'm not overwatering. Are they overfed (nutrient burn)? I use plain water and applied Zamnesia Monster Bud Mix (Pellets) to the soil before the grow. Scared for my first harvest.
