100% there is , but the right kind is key/clutch I swear by monosilicic acid, and after switching from the standard many years ago I’ve never looked back, in fact I give them small amounts from the start of true seedling and even add it to my clone water and all, I’ve done side by sides and even done room to room with my mentor it’s clearly a valuable additive. I’m almost positive (lemme check) that NPK stuff is the goods. The problem now is companies know people have caught on and they charge a damn fortune for the mono’s like power si etc. I’ve found a cheaper alternative called Zumsil that I absolutely love it’s made by black swallow and it’s killer. And not ridiculously priced either.
