I've been following various grow guides both here and at cocoforcannabis.com. I've gotten great advice, and my plants are looking fabulous. First grow in coco coir, and plants are about 7 weeks, 2 into flower.
All along I've been using Silica Blast at initially 2.5ml/gallon. (I mix 10 gallons, dump into a 14 gallon container and often top up with some RO water that might have some cal/mag in it. I do this to reduce EC as I'm feeding 5x/day anyway and don't need high EC.)
I mix the Silica Blast first, then wait an hour, then add cal/magic, GH nutes, and finish with some humic acid, yucca powder and finally some h2o2. I adjust the pH to 6.0 and keep it there with a Bluelab controller.
Now for the questions:
1. pH: I've seen a couple of articles on general use of Silica that state it won't stay in solution with a pH under 7.0. True? I'm at 6.0.
2. Delay after adding: I've seen virtually no mention of mixing Silica and waiting before mixing other nutes. I have seen articles that mention mixing it separately, and I've seen articles stating to add it at the end of mixing up nutes. And I've seen various forum messages stating it being added at the end as a pH increaser and not much more.
Where is this 1 hour delay coming from, and is it universal or only apply to specific Silica formulations? In particular is my Silica Blast any different? It mentions nothing about interaction with other nutes on the bottle.
3. Quality of flower without Silica" I ran across an argument that basically said your flowers would smoke better if you discontinued silica at some point during flowering. Thoughts?
4. Interaction with nutes: There seems to be a clear dichotomy of views depending on where you look. Don't add it to nutes because it causes some sort of problems versus add away, no issues mentioned.
Hoping for some clarification here. I'd like not to have to wait that hour...
