Hello new grower here, thanks for having me. I have 3 plants of different strains that are starting to lighten around the edges and I don’t know exactly why. They’re about 2 weeks old. I gave them their first nutes a couple days ago (GH, 1/4 tsp micro, 1/8 tsp each of flora and bloom per gallon), the temperature ranges in the 20s, though it dropped to 15 last night and humidity between 55-75%. They’re under a dome right now. I mist when the humidity drops below 65%. I haven’t watered much because the top of the soil feels moist all the time and worry about overwatering. I’m growing in promIx HP with added perlite. I use well water with a pH of about 7. I have 450 W LED lights at 25% set about 5 inches above the tallest plant and dome. Could it be stress due to the fluxes in their environment? This is my first grow so I really have no clue. I have already had 1 seedling completely die on me so I’d like to nip this in the bud... The panic in me says to give them more nutes... Help would be very appreciated thank you!
