looks over watered and possibly mites, you need to check under your leaves with a loupe for parasites and slow down on your drenchings

I have not watered her in a week now after the transplant. Also some leaves are a dark green color and some have burnt tips on leafs. I'm only using 1/2 teaspoon per gallon of fox farm fert to start off plants with. I did notice some bugs on bottoms of leafs looks like maybe spider mites I've been treating every other night with some might wash and I can't see any bugs anymore. Should I fallow up with the power wash? Is there anything better I can use for bugs??? I mixed some promix and foxfarm soil due to plants being young yet afraid of nutrient burn. This is my first grow I bring them in at night and put them back outside during the day... Last time I checked soil ph it was low at 6.1. Any tips on raising the pH?

Amended soil with dolemite lime and then you won't need to watch ph so close, to raise ph you just raise the ph of your waterings
