Dry tips and some with yellow spots

Not only do they have dry tips but some others have both burnt ends and tiny yellow spots all over the top. When looking through a 60x mag glass I saw a spider mite. Is the yellow spots and burnt ends because the spider mites Or is it lacking something too?

Its not mites, how close is it to the light?

my girls went thru the same its light and may be nutrient deficiency's . try backing up the light and when you do get a warm damp hand towel and stroke the leaf from center to edge or cut them off. be sure you spray your plants every now and again.

The leaves that are more exposed and closer to the lights are not really drying out like that and they are about 2 1/2 feet away from the light. The ones in the pic's came from the middle of the plant, more like 3-4 foot away. I just started misting them a little once a day for the last week and it looks like it might be helping. I was told sparying the plants when flowering wasnt good. Understandable that your not supposed to hose the girls down. Also, I noticed a 20 degree drop when they sleep which cant be good either.

whatre your temps day/nights max/min? do you supply cal-mag? how old+big are the plants and what size pot? what is your feed and schedule?

10-15 deg drop max, 70-80 deg day cycle, is the first step. also u should figure out the temps

12h 12h day night
High day:81 Low night:68
I havent tried cal-mag.
41 days flowering
4 plants in general hydroponics waterfarm
cycling a mix depending on day of the week of soul synthics grow, bloom/swell, root organics bloom

lol dont use a hose xD. n how bad is it to spray em? cuz i got a little red bottle and i do like twice a light cycle.
