Hello, First time growing plants and I’m having an issue with my lower fan leaves yellowing and brown spots appearing on them as well. Before I get too in depth, here is my current setup.
-Bubba Kush Feminized Seeds
-Indoor grow tent, Temps 70-80F, RH 50-70
-T5 Grow light at ~10-12 inches over canopy
-Solo Cups filled with Coco Loco
-24/0 time cycle
-Watering with tap water ph’d to 6.0
-Couple of fans, intake/exhaust
-Using Dyna Gro Nuits
We are currently on day 25 and since about day 21 I have been experiencing these brown and yellow spots. I have been watering every 36-48 hours depending on how the soil looks and the weight of solo cups. I initially thought it was a calcium issue so I decided to give it half of dyna gro’s Week 1 Veg schedule on day 22 as I did not want to overwhelm the plants but the issue seems to be worsening. Aside from the yellowing and brown spots, I am having some wilting and the tips seem to be yellowing as well. I have added a photo so that if what I’m describing doesn’t make sense. Looking for some guidance and help, I appreciate it guys/gals and also, Merry Christmas and Happy Holidays!
