Soil hippie weighing in. 1st you've got slight cupping. You are over watering. Wait until those bags go feather light and then feed. Careful though. Moisten the soil first before you dump the entire thing in there. Like a slow quart. Let the soil loosen up and then slowly feed in the rest. I've found on really dry soil that if you just dump it in, then it's going to just roll out of the sides of the bag without hitting the bottom. You want that entire root zone wet. Have no idea what quantity you are feeding but in 5 gal grow bags I use 1 gallon typically per feeding. As they get thirsty (vertical growth stopped and in full bloom), they will lighten that bag every 24 hours or so. Instead of a schedule I've got a moisture meter. Plop that sucker down every morning and figure out what you need.
Get some
diatomaceous earth for those mites. Sprinkle it at the base of your plants. That will get the little fuckers coming up the sides of the bag into the soil. I can PM you a pic of a spinalsodal formula I use that is easy to get, certified organic and doesn't mess with your buds. Also kicks the dog shit out of mites without nuking your plants. Some of the fatty soaps suck ass in that department.
The other thing I'd recommend you do is spray them daily with a PH balanced Epsom salts solution of 1/2 tablespoon to a gallon. Mist them. They will love you.
I spray in the evening before I take the m in for the evening for mites. And I hit them all in the morning with cal/mag.
Think that's it other than your nute line up. I've had tremendously good results with
Earth Juice Seablast. I use their Grow, Transition, Bloom, and finish the last 3 weeks with Bloom Master. I did a test between Fox Farms, GH, and those above. All of the micros you need for each stage are already there. It's a simple mix and balance and it is formulated for soil.
