im thinkn they were just stressed. the leaves were curled a lil bit for some time and i also noticed the leaves fringing up for awhile. very slow drainage leads me to believe that the roots were suffering lack of oxygen. and posibly salt buildup, but they never showed signs of nute burn, so im thinking ph was way off(i hadnt been watching it, gona go get a ph meter for the next batch.). and who knows maybe my digital thermometer/Digital humidity isnt acurate, it was only $5 :stoned:, so i might get a better one or just get atleast one more to cross check its acuracy.

i should be fine in these 1.5G, my friend uses these as well and he grows them to about 4' and gets a huge quantity off em. im using the hps for veg too and was only letting them get to about 1.5' before i switched them to 12/12, they stretched alot once i switched them. so im gona let the next batch get atleast 3' before i switch them., keep an eye on the ph levels this time, and add way more perlite since i was using it way too conservatively and not adding much:stoned:. we will see.
