yeah air conditon is very important, but by the looks of the leaves they seem to bre getting heat streess!, i know you said ya had the lamps three foot away , but what temps do the leaves get??they look very de hydrated and curled down the edges!. you should always stabalise the arlita b4 using it { ph that is } normally by soaking over night or 24 hrs is ok, but for the amount of arlita ya have its alot of fluctuation!, thow much water is there in the bucket! and how much of the pot sits IN the water?,,
the evapouration of water will also effect the ec and PH of the solution, the less solution ya have the quicker the fluctuation occours,its the old piss in a puddleand it turns yellow,however if you piss in a lake!,,definately need to concentrsate in making a goood enviroment for your plants especailly in hydro, GOOD AIR as mentioned previously is a must,
good luck!
