I currently have two plants and one is on the fritz, both the same strain, currently in FFHF soil, PH is around 6.5 and lights are Vivosun 300watt two feet above at 50% intensity. Really only watering when needed, checking soil about an inch deep to make sure it's dry. They're in 7 gallon pots, currently feeding Jacks 10-30-10 bloom. Clearly something is up, yelling and browning started literally 2 weeks into flowering. Stocks on the plant are purple as well compared to it's sister plant, room temp here is 70f and 55% humidity (wish i could get it a little higher). Any ideas or just ride it out?

I think I see some indications of them being underfed. The red pigment on the stems can be a sign of stress, but it doesn't tell us what the cause of the stress could be. I'm wondering about the light. How much power are you using? Also, are the plants getting any light during their dark cycle?

Have you tried epson salt foliar spray?
And the tips look burnt also.

Red circles mark the septoria I found. Blue marks the nutrient burn.
