my gut is telling me its overheating cause i had the plants in a greenhouse for a day that didnt have enough ventilation and it got about 80 degress here. but i have also been having a little pest problems so im not sure. i moved the plants out of the green house to see if it clears up. only 1 plant has noticeable damage
