Stop fertilizing and give it a 6 gallon flush of fresh, pure 6.4-6.5 water. That should remove most of the build up of fertilizer salts. Then go slow, start fertilizing 1/2 strength. pH all water into pots should be in 6.4-6.5 range.

It will take a week or so but all new growth should be fine. Slowly raise fert levels as plants need more.

By the way, you're pots look alot bigger then 2 gallon pots. You should flush with 3x the water per gallon. So if they are 3 gallon pots, 9 gallons of water and so on.

I suck at soil, so I could be dead wrong.

2 pale leaves, 2 weeks into flower, I wouldn't worry.

Burnt leaf tips, might be a bit too much fert.

Good luck.

test your soil pH and your soil EC. Runoff while a helpfull indicator is a bad way to determine whats going on in your soil. You actually have to test your soil.
If pH is too high water with a dilute nute solution (like 1/4 strength, pH should be around 6.0) with ample runoff.
If pH is ok water with a dilute nute solution (like 1/4 strength, pH around 6.66) with ample runoff.
If EC is too high, then definitely water with a very dilute pH balanced nute solution (less than 1/4 strength).
