You do have a heat issue, do you have a fan that may help.

But as for when to harvest use the trich's. Harvest at the first sign of amber!! the plant will go thru flowering cycles meaning the plant will produce new pistiols in cycles first round will start to turn mostly red. Then all of a sudden the plant will burst out with more new pistals due to not being fertilized the first try and is doing everything it can to reproduce. The plant may do this 3 or more times before she finally has expended all her energy and begins to shut down. This is when amber trics begin to appear and is the optimum time to harvest.

By the looks of your plants you may be close to being ready so keep a close eye on them.
