Curling leaves

shifting pH can cause waves in leaves due to variable growth rates that result. However, The first serated leave and even the next 3-fingered leaves can show odd things and be perfectly healthy/normal. So, The 2nd set of leaves looks healthy, i wouldn't worry too much. Could be environmental too, but again, new growth looks fine. Definitely wait and see and be mostly confident it's nothing. what i do see is a very unusual drying pattern around your plant that indicates you aren't watering properly. Do not water superficially, don't choose the volume - you give what is necessary to do it right. So, with a tiny plant in a big pot you water an area just wider than the current canopy size of the tiny plant, but make sure that wetness goes all the way down -- even some runoff is fine. Otherwise you create untual drying patterns inside the substrate, which is far worse than the top layer, of course. Roots turn toward greater moisture. if it dries inside out that fucks up optimal root growth. Under normal conditions you water entire volume of substrate with minimal runoff (or 10% in soilless) and wait for top layer to start to dry before repeating. You mimic that as best you can given the context and increase the diameter you water around the plant as it grows. How fast it drinks is the key here. You don't want water stagnating in a pot or a water tank for long periods of time. Being absorbed into substrate doesn't change that. Just a incubator for detrimentla microbes and such. if in soilless, religiously get a 10% runoff. tiny plant / large pot = shit ass watering, elevated risks, fucked up root growth, all sorts of reason to avoid it... I've done 300-400+, maybe 500 up-pots and yet to see one get shocked. Even the time i stupidly didn't water before hand and tried to up-pot when the substrate was too dry and it half-disintigrated as i placed it. That plant didn't slow down -- although i don't suggest shooting yourself in the foot like i did. It was 100% avoidable with basic common sense. Don't listen to the urban myth that you cannot up-pot an autoflower. Up-potting is not stressful and really easy to do it. The headaches of a large pot/tiny plant far exceed the infinitesimal chance you cause "shock." Simply won't happen with a basic up-potting. Just don't manhand/destroy the rootball with retard strength and all is well. Good sources will verify this. cococforcannabis is one of them. Read their guides and dr photon's corner articles. ignore the rest. Forums are a place rife with misinformation and misguided people. save the time and frustration. do it right.
