pH issues? Yellowing curling leaves.

Hello - This forum has helped a ton as I start my first grow. I'm trying to keep it simple, just soil in buckets, indoor grow. I started with a single 250 MH and supplemented with 3x standard shop fluoro. I have since acquired a 400HPS which I haven't gotten to implement yet, it'll be for flowering.

Seeds were germinated beginning of Jan, so plants are ~65 days old at this point, in 10 qt pots.

Not knowing any better at the time, the plants were put in some miracle grow, and I was fertilizing as well at first and have stopped adding any nutrients until I get this issue figured out (~3 weeks now). I am watering 'whenever the pot feels light' (usually every third day) out of standard tap water that has been let sit out overnight in buckets. It measures about a 6.5 ph with a standard pool-drops test.

I do know I have a pest issue(some kind of mite, whatever it is it's hard to kill), but I don't think my infestation is bad enough to cause this kind of curling and yellowing.

On to the pictures.

Plant 1




Plant 2



Plant 3



I took plant 2 off the rack and flushed it with ~20 quarts of water. The PH of the wash was about 6.0, nothing too crazy. I'm really nutrient-shy now and wanted to get some opinions. Does this look like my soil is too acidic, or do I just finally need to start adding nutrients back into my watering schedule?

I'm going to bug bomb tonight and then wipe down each leaf on the plants to try to put this mite issue to bed.

Thanks for any help you can give.

- Dix
