Looks like early nute burn, a flush is probably warranted.
Thanks for quick response. .do I just use plan water how much don’t want drown
Also is it OK to take them outside on sunny days to save on elec
Yes, that shouldn’t be the cause of things, most likely. As long as they are not shocked by an extreme dramatic change in temperatures and you don’t have the container baking in hot sunlight causing the soil temp to get way too high. Many people will move their plants like this with fantastic results, the idea is always acclimating them to extreme changes in temperature slowly.
