Need help diagnosing... plants took a turn for the worst - Cannabis Infirmary - International Cannagraphic Magazine Forums

So all the sudden my leaves on my plants look like this. Happened almost overnight to 2 separate tables with 2 separate rez’s. One table is 5 weeks in bloom, the other is 2. I use GH Base nutrients with their feed chart at about 2/3 strength, with Advanced bloom boosters (overdrive, big bud, bud candy) at half strength. Also I use terrpantor. I use water ph’ed to 5.8 any advice would be appreciated. Thanks

Maybe a case of heat stress, just checked my controller and it said my temps maxed out at 86.5 and this issue doesn’t seem to be affecting the couple of shorter plants I had on the table or lower leaves

Only/mainly older leaves? Then it's likely magnesium deficiency. That one can occur quite fast and results in interveinal chlorosis.
Got other pics including whole plants and other (different) leaves?

...i'd say heat stress is unlikely, 86.5 ain't nothing, just a little warm.

peace, bozo
