3rd grow

First week went smoothly, all surfaced on October 31, so I let the new seedlings get used to the light, then turned it up to 300w/50%. Continued to leave the HLG600H at the top of the tent about 40” above the ‘canopy’ since there’s not a lot of stretch. PE#2 had a slight nutrient burn on the leaf tips. I’ve had this before with the Coast of Maine soil, and it hasn’t progressed further
