I'ts not the yucca, it's the silica. Had this same problem when using EH and adding silica, but no yuccaUp to you. Doesn't really matter. Nothing locks up.
From my experience. Grow and Bloom already have yucca in it. When you add it, you'll start to see the res bubbling. That's why you don't see yucca in their feed sheet. I did add yucca first once in a while and my res starts to bubble. I threw in grow or bloom powder will some sat on top of the bubbles making it harder and longer to mix
'I've read the first 10 pages and everybody breaking down other companies nutes. Read the last 5 pages. So...What's the deal? Is it the ratio (3-1-2, 3-1-4) or is it the calcium to the nitrogen (1 : 0.8, 1) that makes the difference?
Above site doesn't match the break down math on page 1. 2 part micro to 1 part bloom and he came out with 333 calcium. I plugged it in on that link and it doesn't match. What's up?
