Hello friends, I’m a bit unsure of where to go here.. I am having a reoccurring issue with my plants. I am new to using LEDs and am wondering if perhaps it is light stress effecting these girls? I’m doing my head in trying to get my head around all the nutrient imbalance info..
my room environment is dialed in and fairly tightly controlled with a climate control system in place.. am keeping PH between 5.5-6.5
Any help would be so greatly appreciated.

That plant needs magnesium. But it could also need magnesium because its locked out. Could b a little light stress as well. We need more info.

I hope I’m wrong but it looks like you had some issues where they wilted
Maybe even before the flip ?
I run a two part that you need to mix two first then a bit of Epsom salt before adding 1 which is basically 15-0-0 nitrogen
But if you flipped em knowing you let ‘em get to dry they could look like that
Otherwise you program looks solid
If that is the case a bit of wetting agent might help to ride out the grow
Crazy you are maintaining that humidity in those temps though

thanks for the help/advice, they might have had something like heat stress or something.. they are in clay balls and as far as I can recall they haven’t wilted.. just seems to be the one strain affects too, the gelatos fine but the skywalker has gone pale/yellow on me two cycles in a row now..
