3rd grow, 1st time documenting.the EP

This week I adjusted the grow cupboard. I added the MH ballast set to 250watts, set to about 70cm+ height. Heat is killing me i can reach 32c on days due to the MH and heat. RH at 45-50% For now the critical orange punch is under performing. Besides the slow growth it kinda looks healthy. I watered with GH micro 3ml for a 4l, added 1ml silica, and had to ph down. I'm also using the GH ph test liquid wich is roughly ph'd to 6 Thanx
