Experiencing problems with a deficiency or toxicity I’m guessing. Watering using general hydroponics series gro/micro/bloom at a 3:2:1 ratio respectively and also adding calmag at the same dose that we are using the gro. Around 40 gallons of nutrient water for 160 plants. Ph’d at 5.8 and using well water that we have had no issues and success with before. However we were not using this much calmag before. Running under LED spider farmer lights at 65% humidity and 78 degrees with lights on 24/7.
Started noticing discoloration from the inside of the new growth as a form of a lighter yellowish color but the veins of the leaves are still dark green. The leaves are also curling down at the ends. Checked the Coco/perlite ph and it read low at 5.1. Just added limestone to each plant at around 3/4 tablespoons a piece. Slowly raising the ph of the growing medium that way but I wanted to post a thread on here to see if any of y’all had any ideas on what might be going on.
Thanks for any help![AC30D8A7-017D-48EC-945A-D141C3AFAF32.jpeg](/data/attachments/4187/4187929-c0569ff3f3bdc0c5f1c037bbd3cc775e.jpg)
