Girl Scout Cookies Extreme

Topped the plants in the photos without light. Reintroduced the Fertmax A&B at 2.5 ml/gallon every other watering, and maintaining calmag dosing at 3-5 ml/gal every other watering. Am I using too much Calmag? I hear these girls like it a lot, and they seem to be doing great! It's a very stout and bushy plant. The undergrowth is getting pretty thick. It actually had 7 nodes at topping despite only being 8 inches tall.
