here are the latest pics of my grow... this first post is from the 4th of this month... this picture was taken with a canopy temperature of about 100 degrees. While this temperature was not consistently 100 it did stay as high as around 90 and perhaps as hiogh as 110 breifly! lower than canopy level, like just above the top of most of the pots, but canopy level for many pants it was 94, but usually was running around 85-90. how heat stressed do these plants look. the first pic ecspecially is edited and the thumbnail or whatever looks wiltd or so,mehting until you click on it and zoom.. it is not though.
I am worried more about lanky growth, and the emergence of 5, 3, and e 1 leafed (where there had been 5-9 pronged leaves), skinny, deformed looking leaves, most prominent in the hottest areas of the grow space. I guess these are "stress leaves" does this mean basically a decrease in total production and just a general stressing of (most of) the plants.

The current probnlem is now the exact opposite as i struggled to fumble in the cold dark (25 outside prolly 40 (hope not) in grow space.) to turn on a heater, which brought things up to about 70. more to come on that after these heat stress oics.

HEAT STRESS PICS.
NOTICE: THE FIRST (i believe) PICTURE HAS BEEN SHAPENED WITH A PHOTO EDITOR. THE LEAVES WILL APEAR WILTED AND EVEN CURLY OR SO<ETHING UNLESS YOU CLICK ON THE IMAGE TO ZOOM IN, THEN IT LOOKS JUST FINE.
