5 days into flowering. whats going on with these leaves?? is it what i think??

a couple days before i started flowering i started getting spider mites a day later i baught some stuff to take care of the problom and sparyed the plants. im thinking this could be a reason the leafs are messed up. maybe the solution burned them because i had doen it once with the lights on. and i started adding dyna-gro and i would add hald the recomended amount when watering. i used it twice and this was the first nutrients my plants seen other then what was in the soil.
im guessing this is nutrient/ solution burn. its been 5 days into flwoering and i dont see any change really all i see is the pistols turning brownish red and getting a little longer. is this normal??

i have these 2 plants under 6cfls at 2700k and 2 t-8 tubes at 4200 k

In the middle pic, labeled as 005, you should cut away the bottom growth. Your leaves looked burned to me, which is probably from the solution. In the first pic the plants look yellow, but that could just be the lighting. During the first 2 to 3 weeks of flowering your plants will stretch a lot, they will drain a lot of nitrogen to do this. You want them to have enough nitrogen to last through the stretch and to keep the fan leaves green for a few more weeks but not enough to encourage vegetative growth.

yes its yellow cuz the lighting there green.
so number 1 the burn is deff from the spray i used for spider mites.
#2 should i continue to use the dyna gro every watering as it says. i still use hald the recomended amount.so should i use it???

how do i keep em greeen? what do u mean?
