think of the shittiest soil you can think of, then think of its shit. it's called water wise and i bought it at lowes (I didn't know about fox farm at the time). I dont know the pH since I dont test it
The leaves look like it could be aphids, but the drooping makes me think over watering... make sure your checking below the top soil before you water again, the bottom of that pot could be drenched.
your right it could also be waterlogged all tho your dirt doesnt look wet.. you shouldnt water untill she starts to droop.. but not curl like yours are doing..
best advice i can give you since you dont PH your water and your hopefully not feeding with nutes, is go out and buy a few gallons of distilled water and flush your soil with 1 full gallon and then wait for her to dry out..
she should look way better.. meenwhile go buy some cheep ph drops $12 and find out what your tapp ph is..
also you should let your tap water sit overnight so all the clorine and floride will evaperate from the water and the sediment will settle to bottom.. (5gal bucket)
then scoop water from the top
