dont know much about hydro but i know one good thing about it is you dont
have to guess on nutes,you put in what works n your good.

as for temp 90f is a lil high ,are you sure thats the highest temp you get in a day?when you said "appears to be drying" makes me think the temp is getting to high.its good to get a high/low thermometer ,it will record the highest the temp gets in a day,
you just have to reset it after you check it.90f wont kill them but much more than that n you start getting problems.i think i would try to find a way to bring the temp down to around 80 at least.

good luck peace

They seem to be coming along fairly well except for what would appear to be burning or drying as well as yellowing at the tips of the leaves... The other just doesnt seem to want Rating: 5
