Foliar weekly with Nitrozine + Penetrator but not had this before.

Plant looks healthy but the curl on the edge of the leaf in my experience is from heat stress what is your canopy temps?

 

[SergeantGod]

Finally cooled in the Pacific NW.... last few days 72-80 but last week it got up to 85. Our rooms stay pretty much in the 72-80 range.
If not heat..........hummmmmm, then what?

what do you water with?

does that mix have lime in it at all? for some reason I am thinking early mag def

 

[SergeantGod]

I'll look for the lime...... I do infuse my water weekly with CAL-MAG.
I appreciate your input and time.........
