Starting off with less is the conservative way. Referring to nutes. Some genes can take more than others. Some can take a lot. Some strains can't take hardly any at all. I can't remember and count all the times I've been stoned and forgot to do the math. Like when I only need and mix for a half gallon but, didn't do the math and overdosed the half gallon with a dose of nutes meant for a whole gallon. And I've seen what you see. Excellerated growth. As an example and my most recent mistake. I planted in Happy Frog soil which has a rep of being a hot soil. Almost dangerously so, especially to seedlings. In my experience the rep probably fits. Then, early on in the plants life, I got stoned and decided for whatever reason the plant needed to be fed some nutes very early on in the plants life. So I mixed up a batch of feed with full strength nutes and only realized the next day what I had done was wrong. So what did I see? Well the leaves curled under pretty significantly. There was some tip burn and maybe a few yellow leaves. Too much nitro I think. But the plant itself thrived over all. In retrospect I was just over the cusp of poisoning the plant. I would say had I went half nute strength, maybe that would be the ideal strength. Or maybe went another week or two before feedIng at all, perhaps that would have been the conservative route and I am sure the plant would have done well, tho maybe not as well, maybe better. Who knows? Unless a side by side comparison of clones with all other comparables being the same was done. Anyway, that was soil so.... Maybe not a perfect comparison. What you are doing my friend is dialing it in bro. I've never really dialed in a specific strain of genes because I've always tried different strains. I have tho, dialed in my methods overall, to the conservative side for a system that will make my efforts successful and productive every time. I certainly haven't dialed in my methods and genes together for the most productive harvest. That would be more commercial and suited for clones. Anyway bro, there is no perfect answer. Sounds like you're not having any serious issues so far. If you do? Simply ph some tap, change your res and let it rest for a short while. Maybe a day like the other poster before me suggested. Then scale back your nute strength and change the res again. And here's a tip. Whe you are PHing your res daily, if yours is like mine, the ph rose .5 or so every day. Add a little ph down in the drain tube. Cup your clean hand over the top of the drain tube and blow in it. Your lips should only be touching your hands not the tube itself. That may not be safe because of the chemicals. Blowing into it will mix your PH down fast. Then check it several minutes later and add more if necessary. By the end of your grow you should have an idea of how much ph down you need to mix and shouldn't have to do it more than once. Me, my target was like 5.8, but the previous posters target of 5.5 to the low side probably works as well. Whatever works and makes you satisfied with your results is perfect. There is no right way. Only wrong ways which are abundant around here with people who don't know any better. But, so far I've seen mostly quality advice from the other posters in your thread. Mostly. Good luck bro. Keep an eye on it always and it sounds like your doing it mostly right so far. Peace and love for everyone and everybody world wide.
