i dont know much about photo trons, but it sounds like your concentration of ferts for foliar feeding is super high for one thing. So some of the problems your seeing is probably due to photo toxicity.

Second, foliar feeding does not make up for regular feeding via the roots. So your probably also seeing some deficiences mixed in with your light burn and poor air circulation. Dont foliar feed with reg water, it can actually draw nutes out of your leaves. Only do this if your humidty is drastically low for some reason.

To save these girls (if they were mine) get some fans, stat, or you will be seeing mold and pests very soon. Cut out the foliar feeding and feed a 1/4 or 1/2 strength nute solution by actual watering. Make sure you ph adjust this water, and ph the outgoing water to make sure your root zone is in an optimum place to start sucking up those nutes. Then wait and see I reckon. Check on your nutes, im not familiar with sugar daddy but earth juice s/b 1/2 to 1 tbsp a gallon, not 4. Just double check and reread everything you can find on the products your using!
