Cannabis is pretty finicky about her ph. You'll want to find out your local water conditions, and adjust accordingly. You can either Google for your local municipal water report, or get a ph kit or ph pen.

Granulated ferts (the "slow" or "time-release" kind) are generally a no-no in container gardening. If the plants are getting overfertilized, (which I suspect they are) there's no way to remove the nutrients or adjust the feedings. (transplant into fresh soil, change nutrients asap)

There's a sticky around here somewhere about epsom salts not being a miracle cure. Find it and read it. You might just be dehydrating the plants with too many salts. If you're going to transplant into fresh soil soon, not a big deal. If not, you'll want to flush the salts out with properly ph'd water.

NEVER let the plants sit in standing water. It will cause nutrient lockout and will lead to root rot. Cannabis prefers a wet-dry cycle. Let the soil dry between waterings.

95 degrees is pretty warm. You'll likely want to try and cool the daytime temps, or keep the night time temps higher. Try and keep the high and low temps as close to each other as possible. (a maximum of 15-20 degrees f. difference, if possible)

tevfik: if your going to help troubleshoot other members grows, you'll need to be much more thorough. This is a medical cannabis site, and I know I'd get pretty pissed were a member to jump in and mention only one issue, when there are multiple issues. Half an answer is no answer, and this is neither the time nor the place to do things half-assed.
