Since I sprouted these things they have been generally undersized(nitrogen problem?) , pale yellow and not healthy looking leaves(Sulfate problem?), and the stem strength questionable, though not in immediate danger.

At first I began taking care of the spider mites that so bastardly ate my leafs.
Then began the pale yellow discoloration throughout the entire leaf, starting at the bottom of the plant and moving upward.
Then once that seemed to start to slow down, I have now noticed that on the upper leaves (where the spider mite formula had previously been), the leafs are now turning yellow and perhaps even crispy from the center of the 5 leaf connection outwards (Chemical Burn?), Any comments are helpful, THANKS! :weed:

btw, if it makes any difference i have been using a heat lamp on them in a normally colder area in order to boost bud production

What types of lights are you using for your plants. And if you sprayed chemicals to kill the spider mites on your leaves under hot lights during the day then yes it is more than likely chemical burn from the mite spray. And sulfur and nitrogen def bascially mimic eachother in the looks category. Please attach pic
