Plants are starting to yellow. Is this a simple N deficiency?
They are in Grodan Delta 4 cubes. Watering them every other day to make sure they are not over-watered. They do not appear over or under-watered. The leaves aren't dropping or cupping.
Week 2-3 of bloom. The other strain still looks green. Using Dyna-gro Bloom with Orca and Silica.
Temp is about 70F.
PPM is about 800. I could increase it to 900 or add plain N.
Last 2 pics are under the HID light but you can still see a the top parts yellowing.
