Using urine @ 1 TBS per gallon or water will provide all the N you need! I stopped buying GROW a few years ago. I do suppliment ThriveAliveB1, Liquid Karma.

When running dro run...same thing.

Superthrive at germination/early veg, is fine. I dont use it when I ramp up to bloom ferts tho, it sends the wrong signal to your plants metabolism.
PlantBoxer Reviewed by PlantBoxer on . CalMag and Thrive in bloom... It's my understanding that N should still be fed, albeit in smaller quantities, during bloom but you need to knock it off in the last few weeks. Is this correct? Calmag is rated at 2-0-0 so phasing it out say halfway through bloom would be a good idea? While I'm here, I should also ask if a similar rule exists for hormones a la Superthrive? I hear people mention they use ST all the way until harvest, but I've also picked up that it can actually hinder full errr, fruitilization! :D Rating: 5
