Leaves drooping around central vein

[DasPachy]

have you checked your ph run-off? check that, but also your roots maybe choking cause it looks like you have no kind of perlite or anything to lighten that soil up.

I haven't, but I will next time I water. There is some perlite in the soil, but I agree that there is not enough. If the roots are choking, will this begin to effect the rest of the plant? The lowest leaves have been doing this for a while, but the middle to top of the plant look great.
