Hey DGC,

First off, thank you for all you do for the community. I’ve been have an issue the last few runs that I’m turning to you for advice hoping you can help. I believe I’m experiencing some sort of magnesium deficiency, but am struggling to correct.

Current setup is a gorilla 2×4, four logic pucks, and two 15 gallon grass roots pots filled with buildasoil 3.0 on its fourth run and introduced avocado tek last run. Watering every two/three days at 6.4-6.5 pH and include recharge at least weekly.  I currently have two pulse monitors in the tent (one pro) and consistently have RH around 60% , temps in mid to upper 70s and co2 around 1100ppm.

I recently had two rounds of foliar feeding with an epsom mixture but have not seen any results. Plants always start off great and slowly start showing signs of deficiency right before flower or once flowers starts; current plants are in veg and may be 6-8 weeks from seed. Any thoughts here?
