Most people suggest to use it 3 weeks before harvesting, even the coco guide says the same. I’ll give it a try this way if i don’t see any change in bud growth i’ll try using it earlier on the next grow.
I’m on week 8 of a 12 week cycle in coco and the plants aren’t drinking as much. I watered them everyday till now by 2L on 5G pots and now i have to do it once ecery 2 days.This is my first grow.
