this week was stressful, temps shot up and i had to switch day and night time, the plants started yellowing signaficantly im not sure if its because of the temperatures, a ph imbalance or because of a nitrogen deficiency. otherwise the plants look lovely, the smell is sweet and pungent. hoping to chop in a few more weeks.
My grow tent is at around 21c when lights are on, is this warm enough to still produce high quality buds? or should i buy a heater to get it up to 24-27c?
