Thanks Kite, I knew that you would have the answer. I knew not to use hydrated lime, but the dolomite lime that I was able to get here is called agricultural lime (dolomite lime) and is not a fine powder, but granulated. It's not as big as the stuff in bags for lawns and I put some in water to test and it dissolved pretty quickly. Did you see my question above ( post #95 )? I'm thinking that maybe for the first 2-3 weeks of flower, I would instead use the Gro and Micro. That would give me an N-P-K of ( 7-1-7 ). Very little P to control stretch as you say and then I would change to the Bloom and Micro which would be ( 5-5-5 ). Sounds like a plan to me but I would like your thoughts. Thanks for helping.
