I use the recommended amount of the seaweed fertilizer that i have. The pH is around 7 and im not sure what it should be. All my other plants are doing fine and they get the same treatment.
Cut your ferts back. Rule of thumb, never use full strength with cannabis. It's better to under do it by a lot than over do it by a little.

You have bugs...the lower fan leaves on that pic show it, as do the leaves in the background on other plants, some of those leaves are half eaten. That would be of more concern IMO
PH is a little high but not terrible. 6.5 for soil is ideal, 7 is tolerable. I would say full strength nutes is a bigger problem and probably to much for your plants.
Also the longer you go with to much ferts, the more the excess salt will build up in your system and your problem will steadily get worse. Another thing to consider is if you are using soil that is pre fertilized then adding nutes to early will cause issues.
Its getting worse, i just put water through them so ill wait a week to give them ferts. Anything else i can do?
I would flush hard core then feed with light to medium nutrient. It always takes 3 days to a week to see things get worse or better when you make changes. Also inspect closely for infestations, maybe put up a bug strip to see what you catch.
Theres alot of like black flying insects (kinda look like flies) on the leaves. And for hardcore flushing just putting a ton of water through the pots?
