Sorry got confused..I was talking about salicyclic acid..which is natuarl PGR.I know foliar spraying works. I have experienced weird lock out here and there. I'm starting to think that potassium silicate might not be compatable with hydro. According to the author it's not because it need a PH of 7 or more. I'm going to only use it as a stand alone and see if my plants are happier. Testing is the only way to find out. I only use coco so it's possible that seaweed and silica might be adding to much K.

To get back on track...too much K makes perfect sense..especially when all we're trying to get is the silicic acid. Thanks for pointing that out. I cleaned up my posts a bit. I can list those links if ya wish..just rather stay on track.
check my second link in the post above, some very interesting reading. The short of it seems to suggest that PH and temps lend in part to the length and quality (size) of the polymer chains...rather than actual solubility.If this were actually the case, that silica is insoluble below a pH of 7, then wouldn't we expect to see rampant silica deficiencies in hydro?

I believe an acid has to be used as such. If you change the PH and raise it, it's no longer an acid. I think 5.5 might be worth a try.@ nightmarecreature
I'm going ahead with my orders of Absorbic acid and White Willow Bark Extract. I'll let you know how I fare. Going to be using with a surfactant and only going to use it 3-4 times the whole cycle. The bulk powders are really cheap. Plan on only raising my PH to around 6.2 for this rather than the usual 5.8 slight acidic for foliar.
Thanks for the caveats about Potassium Silicate..lots to learn there, using as a foliar!
Let me know if this works..it's a pdf file...you have to read this..Excellent, that did the trick, at least for the first page. I wonder if root associations with fungi and bacteria makes the question of pH somwhat obsolete? As in these organisms may be able to change the pH in the rhizosphere itself, or perhaps scavenge the silica and make it avalable to the roots of the plants when it may otherwise not be. Worth looking into.
interesting I can't wait to find out it's natural PHI believe an acid has to be used as such. If you change the PH and raise it, it's no longer an acid. I think 5.5 might be worth a try.
