Hi @TerpDerp! I would not worry at this stage. Potassium is mostly used during the flowering stage, considering you're growing in soil your medium is supposed to have enough nutrients (Potassium included) for the first weeks, and even maybe for the entire vegetative stage. Less is more. Remember it's always easier to fix a slight deficiency than to recover from a slight toxicity. Your plant looks healthy, just keep an eye on its coloration and growth speed, in case you see a deficiency coming. Hope this will help, keep us updated and happy growing! :facepunch:

@Stick, thanks for the input. I amended the soil only slightly with bat shit, but other than that, I’m adding as I go. I cut nute regimen to 75% for the first 3 weeks of veg and they look healthy so I’m essentially going by what the plants tell me. My soil also contains 30% perlite by volume so they are loving the drainage. I just have to monitor the soil moisture more so than outside, obviously, but they are doing well so far. And yes, recovery from underfeeding is wayyyy easier than dealing with toxicity...so if they are a bit starved, they can tell me and I can add bit by bit. Thanks again for the info, my friend.

@@@@lilbp420, yes, going to start mainlining midweek. They seem a bit underdeveloped for what I want at this point. Currently at 5 nodes, but I want main stem to be a bit more beefy before topping and LST. Also, I’m running 6tsp Bloom per gallon spread out over the week and between 3 small plants with pH correct H2O added in between feedings. Don’t know if I’m doing it right, but the plants are vibrant and don’t seem to be lacking. Amended the soil with bat guano and 30% perlite by volume so I’m really relying on the plants to tell me what to do next. Indoors is tricky, but fun so far!
