Well, four days after my last post and the two girls are growing ... but, I must admit, they do not look half as perky as my last two grows... herbie says it's the heat...and many of the leaves are dry to the touch...and yellow spotting and leaf-tip burn continues to plague them....but...

....there's been a serious cold snap where i live ... the girls are growing in my cold attic (albeit in a self-enclosed light proof box with intake and outtake fans)...and my friendly hydro salesman suggested i use an aquarium heater to get the water up to about 24 C. Indoor temps are about 28 C. Does this sound alright to all of you out there? Lamp is 250 HPS, about 10 or so inches from tops of plants.

all best and thanks,

Some background...these are two feminized 'Oasis' plants, and I've been upping nutes over the past few days (using ec meter to measure levels). Yesterday I bumped it up to .9 from .7, and this morning I found one plant all shrivelled up and the other one, while looking OK, with yellow spotting on the leaves. I threw two litres of fresh water in there, adjusted PH, and brought nute levels down to .7. Should I simply wait and Rating: 5
