Woke up a few days ago to this. My plants are starting to yellow. They have about 5 weeks left before harvest. I’m hoping it is a nitrogen deficiency and can be corrected. What do you all think I should do?
pH - 6.0
Temp - 75°
RH - 70%
medium - coco coir
Nutrients- general hydroponics trio w/ cal mag

Look kinda hungry. What are your ppm going in and what is your runoff pH and ppm?

Nitrogen deficiency shows up on bottom leaves first. Like @Borderryan22 said, numbers would help diagnose your issue, a support ticket would be best, you can search it and copy/paste the ticket, answer all best as you can.

Update on the GDP. They were hungry. I increased the nutrients in the reservoir and incrrased the frequency of flood and drain to once a day for 15 minutes. I removed the dead leaves and they seem to like that. Increasing to twice a day on 1 May for the final 3 weeks before harvesting.

Glad they are looking better.
