So i am now on week 3 since my plant was a seedling and I have had some ups and downs. I am currently growing a malawi gold autoflower.The conditions in my grow tent have stayed pretty consistent with a temp of 72-82 degrees with 40-50% rh. Everything is all well with the plant whenever I switch out my nutes, but around 1-2 days later the plant begins to droop. I thought there was algae in my dwc so i flushed and got my plant in a fresh reservoir. For the first day it loved the new resevoir and perked back up within a few hours. When I woke up the next morning my plant looked all sad and droopy again. This is so frustrating because I feel that I've done everything. Pls help <3 Other info: 300 watt led (30 inches from plant) Res temp: Unsure but is definitely on the cooler side Ppm: started with around 660 and is now 640 Ph: 5.8 currently but won't stay in the range of 5.5-6 for any longer than 5 hours
