First ever grow

Plant 1: had the light too close. I didnt measure, and did it by eye. as you can see from the pictures this had some reprecussions. I saw it pretty quickly but as it is growing it is obvious that it did have a bit of a setback in growth. Plant 2: doing well, nothing to report. Plant 4: doing well, nothing to report. During the week it took some effort to get the climate conditions right. its winter and because im growing in my basement i have bought an romberg hortiswitch plus an heating mat. climate seems reasonably stable at 24 to 25 degrees during the day and 21 to 22 degrees at night. humidity keeps between 40 to 50% so thats pretty much perfect so far. At the end of the week i found this app for measuring light intensity and whatnot. Definitly helped to get my light dialed in just right. Kept watering the plants to an absolute minimum. Soil was already flushed somewhat so contains lots of water.
