@Med_in_tropic I thought 6.2 PH in coco during flower was perfect no?

PH 6.2 is a bit low during flowering. With increase in phosphorus and potassium given during flowering, these blocks calcium and magnesium. Calcium and magnesium are not mobile. They are stored in leaves and top buds before flowering. My strategy would be to make sure pH is right for calcium absorption during veg. Then spray calcium and magnesium to leaves and buds during transition. Since these won’t move up through roots very much. After saying all these things, my leaves also yellow and drop. Finally, i griw for buds and not leaves.

Not much to do now. So close to harvest. But it's always good to know what went wrong 💚

Is that i see entire canopy, it’s def potassium. Your buds used it all up 🤣🤣 freaking thirst monsters. It’s not watering as the leaves are not slumped over looking sad.

It’s a mobile nutrient as it’s being pulled from older leaves to keep younger leaves alive Nitrogen ( nope, plant doesn’t need any of that at the end ) I think it’s potassium tbh Phosphorus causes the purpling of the fan leaves Cool thing is that you harvest in a few days Flush first to get out all salts, excess nutrients Tiger Bloom 0 - .5 - 0.8 And it’s organic ( no need to flush it) Fast acting also as it’s liquid state. Can do heavy feeding dose and then put in 36 hours of dark before chopping. Last thing : what is humidity like in there? You at 60% or less…..
