Been using aptus monosilicic acid for a while now. Crazy expensive. Don't personally think it's worth it for spoiled indoor plants. Just got a silica tester from floraflex to try but it's very watered down
Tis pricey but very effective. Was using Silicium brand. Would buy it on sale/clearence and would only use half the suggested amount. Jeff from New Millennium gave me a couple of bottles as well.
I'd still use it if I was in coco, but use RAW silica as it has plenty of time to break down in in the soil bed. Craft Blend has it in the mix as well. Only use half the suggested amount every other week
