I would start that stuff around the exact date you switch. How much.. depends on what your plants look like... DO they look hungry..?

I would always dilute nutrients and error on the side of "not enough"...

It is very risky feeding plants without PHing water....

Garden Knowm Reviewed by Garden Knowm on . What do you guys think I was wondering if the soil I got is going to be good enough for the whole grow or do I have to add any nutes to it. I got some clones already in rockwool with the roots coming out. They are about 3-5 inchs high right now and Im about to get them in some pots. Ill be using a potting soil with the follwing ingrediants: sedge peat, sphagnum, peat, pearlite, bone meal, feather meal, bat guano, seabird guano, rock phosphate w/humates, lime, and fossilized kelp. The bag says its good for up to 60 Rating: 5
