Plants are all different bag seed, so that explains the irregularities..
Environment is perfect.. 40-60% humidity @ 70-83 degrees with 700ish average co2 ppm.
Under a 290w --- spectra LED
Run off ph was around 5.8 last watering when I checked.. will check again this time. I'm thinking of adding 2g of hydrated lime per gallon of water (my water is 6.6ph @ 90-110 ppm.. it's half tap and half dehuey water.
I am using roots soil with subcool supersoil in the bottom. The soil did not have a chance to bake for 30 days like suggested so I am thinking that the ph just hasnt balanced yet.
Plants are pretty old to say the least, they've been defoliated once from the first round of nutrient burn. I am just trying to learn from these junkers, the good genetics are under the t5 as I speak.
Thanks for any help.
