Leaves turning yellow and droopy

Hey Growmie, if I read that right, there are a few issues. Less water more frequently at this point is better. I know the pots are big, but your roots are small, and could be drowning. Combined with the nutrients at that volume, definitely gonna lead to some wilty, discoloured plants. PH your water to 6.0 and 6.2, and wait! Lol, the pot will need some time to dry out , the top layer may get dry, but the plant will tell you when it’s thirsty again, just ease back for a bit, and hope they will recover. Don’t worry 😉
