How many times in a week should I water with ferti...

Hi @fategrows! In soil I usually feed once a week starting by week 3-4. I trust my soil mix to do its job for the first weeks, then I look at my plant's reaction and I decide of the feeding schedule depending on the plant's health. Remember it's always easier to fix a slight deficiency than to recover from a slight toxicity, so do it step by step and pay attention to the signs of a deficiency. If you feed too often and you never water to the runoff, chances are high for your rootmass to develop salts buildup, and when it happens in late flowering, you're screwed. Regarding nutrients, less is more, unless the plant is asking for it. Hope this makes sense, keep us updated and happy growing! 👊
