These White Widow auto fem plants are now 4 weeks old. They look healthy except some spots on the lower leaves. Is this a problem or just the oldest leaves dying?
They are in 3 gal fabric pots with coco and vermiculite. All water and nuets go in at 5.8 ph. I am using Bregman’s grow fertilizer at this point with cal mag added. The lights are on 18/6 and the light is a full spectrum LED 600W that has worked fine in the past. The temp runs about 75 with the light off and around 78 when the light is on.
Any input would be appreciated.
