tacoing leaves, brown spots

[thatswhatIsayin]

I think i caught them early because there doesnt seem to be any more spider mites, yay.

but now i seem to have the "tacoing effect" on some leaves and many new leaves are curling down like talons. and one leave has a couple brown spots. Let me provide you guys with more info so you can help me out

Im growing under 400 watt and 4 100 watt cfls for side lighting in an aeroponic system with hydroton rocks. My humidity is low at around 25% and my temps are between 75 and 80 degrees. I am using the techniflora starter kit and recently started using neem for spider mites. My reservoir is at just under 400 ppm.

I have read that the curling could be from too much Nitrogen or possibly a magnesium deficiency. What do you guys think?

Here are some photos to help you guys out.

All the pic links say page not found.
Over watering may be the cause of curl. Leaves starting to Tacoing effect is stress and brown spots on leaves usually means nute deficiant. pics would help.
Just my 2 cents.:jointsmile:

Looks like heat. How far are the lamps? Are those CFLs 100w actual wattage or equivalent? What are the reflectors (for the walls and lights)?

Here, detailed form to fill. You can get better assistance if you fill the form.

i think that its to dry and they hold moisture underneith the leaves. i have the same problem but i want to avoid mold so maybe throw a few damp towels in your grow area daily and get some humidity in there. hope it helps!

watering at 1 min on and 4 off??? overwatering

the timer is for aeroponics, what should the increments be?
