Hello,
A bit ago we had a few unusually hot days which resulted in some very high and undesirable temperatures, I believe this plus a pH that was on the high side for too long resulted in the issues I am currently seeing.
I originally thought the leaf discoloring and leaf tips pointing up was just heat stress so I moved the light further away and was very mindful to keep temperatures cool.
A few days ago I noticed brown spots / motting starting to make its way up the fan leaves and closer to the actually sugar leaves / buds, which of course I would like to avoid if at all possible.
My setup:
Strain - JillyBean x White Beast (Unknown Bag seed origin with high yield and trichome traits)
600 Watt HPS
Fox Farms Ocean Forrest
Fox Farms Trio + Bembe and Cha Ching
Hygrozyme root supplement
5 Gal Smart Pot
I think the root cause at this point is a potassium deficiency brought on by the heat stress the plant experienced. If anyone on these boards could confirm or deny and provide some practical advice it would be GREATLY appreciated!
Happy growing.
