At least you know what went wrong and you have clones. If you like the seeded smoke it will be easy to get sensi next time.
I like to use high P bat guano when I see signs of P deficiency in flower. Works pretty fast to. I also started using some P microbes when I see signs.
Also I don’t know why you’re tossing all the leaves. They make good mulch and break down into usable plant nutrients.
Here’s one of my plants in no-till soil that I didn’t supply with enough P during the beginning of flower. The added 0-7-0 guano has helped slow down the progression a bit.
If you don’t want these pics here I’d understand. Just thought it might help. Ignore the plant next to it. That’s my first coco attempt.
8-30 - First started seeing the signs and fed with guano next watering.
9-23 - The progression has slowed but the plant is still cannabilizing itselt. One of my cover crops have gotten crazy too,
Super helpful thanks I you for showing your example and experience!
