Have a gallon of Jack’s 321 mixed and ready to use. Can someone tell me how to determine what volume (ml, oz etc) of Jack’s to add to each of my three Purple Kush plants?
I just drench each plant until there’s runoff at the bottom @filtertip. If you mixed it 18/6/3, that’s all you do.
May want to mix another gallon. Feed till you have 10 - 15% runoff. It is best to have the plants on risers in the saucers. Better yet is to have the plants sit on a rack with a saucer below each plant under the rack. This is what I cobbled together from stuff I had.
What medium are you using?
What size tent?
If photos, now is the time to top and LST.
