sorry for the delay mate,...
She needs food badly, complete food, not just PK,.. that soil mix is very sparse for nutes... you should have been feeding from week 2 at least,... most any general bloom nutes will be OK as long as there's
some N in there, not a bloom booster like the PK13/14 ( BTW, this is an 0-10-11 ratio in North American conversion; look it up at CANNA's website and you'll see what I mean), point is there's no N in this formula...
Symptoms: I see Ca, P, N and some micronutrient defc's (paling at the tops) starting,... do what you can to feed here, but it's too late to get hermuch bigger or yield more, just try to get her across the finish line with something decent,...... Get proper cannabis nutes next round and start them sooner,....
