The more data you can get, the better. Get yourself a thermometer and hygrometer, a digi one is easiest and best.

 

You should always try and increase nutrient levels slowly, try by .1 to .2 ec each change, this will reduce shock from higher nute levels.

 

Looks like it could be pH, try moving down a bit to more like 6.2 - 6.5

 

Heat could be a deciding factor as well, and your hand is not a precise instrument.

 

Hope that helps
