1st grow and I’m in the 3rd week of flowering. I have 5 White Widows growing in a 4x2 tent with 400 HPS lighting. Using Fox Farms nutrients according to directions. Have the felt pots and air circulating in tent. Temp and humidity have been constant no issues. Water daily 3 days nutrients 1 day water. Yesterday was the water day.
Today when the lights came on I noticed one of my plants is having issues… See pictures This plant is closest to oscillating fan so gets a little dryer, so I’ve been giving a little extra water - top of soil is always dryer. From what I’m reading in the forums it might be a low PH issue.
Do you think that is the issue and how do I fix? Just water with correct PH’d water?
