Hello all, so I’ve had quite a few grows using buffered coco amended w/ dry organics. I’ve been very lucky with the results but I’d like to gain a little better understanding of the specific products I’m using. The success might be because of something I’m using or despite of it.
Anyway, I amend my coco w/ a dry 4-4-4 fert (for veg), a 2-8-4 (flower), myco, and EWC……those have been a constant base. I mix in a little of a few others and top dress with them also.
My questions are specifically about:
1. Bone meal (3-15-0)...I know it’s a great source of phosphorus but HOW QUICKLY IS IT AVAILABLE ? And HOW LONG DOES IT LAST?
2. Langebienite (0-0-22)….I know it is soluble and the benefits it provides, but what about AVAILABILITY & DURATION?? I should note that I crush it into a very fine powder, which causes it to dissolve faster.
I had been told that langebienite takes 6 weeks or so to break down and become available, but I’m thinking that may only be the case when it’s mixed into the medium in the larger pieces…..if crushed into a powder I’d think it would act faster…??
3. Gypsum…..probably 1/3 of the plants I’ve grown have required a small amount of cal mag.
I bought some gypsum powder recently and thought it could be the organic source for calcium. I added 1 tablespoon per gal of medium when I prepared my initial mix.
Same questions here…..how quick and how long??
It’s interesting that my current grow, which is 3 clones, all different strains, was the first time I’ve tried gypsum powder. Early/mid veg one of the 3 plants showed a moderate magnesium def.
I didn’t know if it might have been caused by the presence of the gypsum, perhaps it (along with my tap water of 144ppm) was too much calcium which locked out mag….
I have a foliar dose of Epsom and a small dose of cal mag (2ml/gal) and the problem seemed to go away, although that particular plant just seems leggy…..but it could just be the strain (fruity pebbles OG)….![892F4632-F0DF-42DE-B002-F24C1A4463E0.jpeg](/data/attachments/4405/4405881-cb053e833a7cbf8cfa7bf5c14be854d2.jpg)
Any help or guidance here is really appreciated….
The pic was yesterday and I flipped them to 12/12 about 5 days ago. I hope they don’t stretch too much as my 2.5’ x 6’ grow space is wall to wall.
Thanks again folks
