First time indoor micro grow. Gorrilla glue. 450wt 18in from top of center plant. Cheap 75w red/ blue florescent. 100w led on right bottom . they are extremely healthy except for red stems on all plants. Ph tester on the way. Turned all other lights off except 450 full spectrum. Thinking too much light. Water. Or all the above… Ty in advance.
Red stems can be from many things, sometimes its just genetics.
It’s hard to tell under the purple lighting.
I can tell you it’s not because of too much light.
