is this nute burn?

Sagging ;leaves indicate root issues look very carefully, burnt tips and edges is nute burn, avoid over watering, but first Flush with 3 times the volume of the pot, with air temperate Ph neutral water, allow to recover in dim light, one day or overnight......avoid feeding for 2 weeks then resume at half the current rate only resume, when you see a positive improvement

Yea looks like you might be giving them a bit too much love.. You've got a little nute burn and they do look a bit over-watered. Wait for them to dry completely, flush, and then give only water until things turn around. They might already be about done by that time anyways.

ye i was thinking to just start giving them only water from now on especially as there is only 3 weeks left was going to do a warm water flush for 3 days towards then end too.
