I consider 7 too high. You need to get your room temps down....90F is too high for good health with cannabis.

Where's Stinky when you need her? She's the soil expert.

It just looks to me like EVERYTHING is off on those plants. I'd use tap water at 6.8 and .......again......consider transplanting to quality soil which will solve much of your problems.
