AN nutrients

dont let numbers confuse you. GreenMachine dude is right,from first pistils until the end. "1 to 6 week of flower" is based on strains with 8 week flowering time.Most people stop nutes and flush IN SOIL for the last 2 weeks. Other people saying they use from 4-9 weeks of flower want to say that they don't give BASE BLOOM NUTRIENTS(like sensi bloom) for the first 4 weeks because the plant is still not into full flower and they keep giving BASE VEGETATION NUTES until they see the first buds. This is completely wrong to me. A cannabis plant won't stop growing to the sun.When buds getting more mature,you'll see growing will slow down but it is still growing buds.If wait for growth to stop and skip on P & K because of this,you would only give it for the last 2-3 weeks of the grow and your plants wouldn't appreciate that.Ignore what 4-9 weekers say, use it from the week 1 or 2 of flower to the end.If you plan on flushing,you can stop giving it or reduce the dosage in last few days. In soil,I would start feeding with bloom as earlier as possible in flo so that it finds some more P & K while going into full flowering.
