So I was dealing with a combination of heat stress and nutrient deficiency. I was not feeding properly; I was only feeding Purple Punch autoflower. I have been advised to feed my plant three times a week.
and will invest in a bigger tent with a better system. I will probably use the current tent I am using to create clones when I decide to grow photoperiods again. I'm holding off on photoperiods until I get a bigger setup. Smaller tents are not ideal for a perfect environment. I was literally feeding her once a week and watering her with pH-regulated water of 6.5 during the week whenever her media dried out.

As of now, the temperature, humidity, and vpd of the plant during the day are, and during its 6-hour night cycle, the stats are at 81°F, 60% rH, and a vpd of 1.47 kPa.
74*F, 64% rH, and vpd of 1.03 kPa

The age of the autoflower strain Purple Punch is 61 days old.
and the expected harvest date is 3 more weeks, probably by week 11 of its entire life cycle.

I'm using general hydroponics to feed the plant and have been using silica armor, cal-mag, floragro, floramicro, and florabloom.
Yesterday I gave her a second feeding, and tomorrow I will feed again. Will start flushing two to one week before harvest.

harvest date is expexted by days 78–80 since she sprouted.

The seed is from Royal Queen Seeds, and the genetics are Purple Punch photoperiod and old Skunk auto. This is my first time growing an autoflower. She was topped and lst at first.
