HELP, i hope there ok

came home from work today and i noticed my one plant is starting to develope black spots on her leafs and some of the leafs are extremly dry! i hope shes not dieing on me! i just recently went from a bar bulb reflector to a air cooled and the temps went from 90.1 to a much better temp of 80.2!!! should i maybey move light closer?

Comments will be appritiated

looks like it could be from the high heat before . the heat may have dried the leaves out and now they are dying off . the black spots looks like somethings up. heat related id assume . move your light closer but not much until you see new growth . hope someone can help more than i did

Bump ! Bump

bump gets your post bACK To the top of page so ppl see it

You've got at least two problems and one's contributing to the other. The crispiness is a phosphorus deficiency but that's being made worse if not outright caused by what appears to be overwatering and/or a Ph problem.
