Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

I don't know what nutrients you are giving? But she's wanting nitro, calcium and magnesium. You can clearly see this, so give her some of these and bodily she will pull through! 🌱👍

Being that your growing in coco i think it's safe to say you need to add some Cal-Mag.

Help! Yellow fan leaves mostly at the base!Help! My girls have shown some signs of cal mag deficiency and I’ve added it at 1ml/l per plant for about a week now.. But it’s not improving or is there something else? Tight for space and wondering if this is also due to not receiving enough light? New growth looks ok?

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

Yellow fan leaves New issue starting week 5 of bloom. The lowest big fan-leaves are getting yellow and that very quickly. She got a organic Biotabs PK Booster compost tea 3 days ago. It looks to me she wants more Nitrogen. Should I add molasses? If so how much? Or is it another issue. PH is ok.

Newer leaves also turning yellow at the tips. Flush?Newer leaves also turning yellow at the tips. Started to give the plant Terra Bloom,Sugar Royal, Pure Zym and power roots again after only giving it water for 2 weeks long. Is this a nutrient burn and will a big flush help it out? Doesn't a big flush overwater the plant?
