I think it is a moot point, "square ~vs~ round pots. LOL
just use 3 sizes through out grow. Like I pointed out.

all purpose would be OK. just don't everdo it. Is peters 20-20-20 water soluble? And why can't you get a real POT nutrient? Just wondering.

Gotta go...feed the farm Peace
latewood Reviewed by latewood on . Transplanting Question I have four plants all 2 1/2 weeks old in 6" pots. They are starting their 7th node, and are all short and compact due to me keeping the lights extremely close. Anyway, root hairs are coming out of the drainage holes. Obviously I need to transplant. The problem is, 2 out of 4 of the plants need to be fed fairly soon, as they are starting to show a nitrogen deficiency, and the cotyledons are yellowing and falling off. This is normal for their age. So, I need to know, should I feed them Rating: 5
