Barney’s Farm LSD auto

This week has been a good week of training and growth. Did some defoliation of Lower big fan leaves and LST on all plants. Started noticing what looks like a magnesium deficiency in plant #3. Most likely from being in a small pot and going through the nutrients in the soil faster than the others. Anyways I just started adding 3ml/gal of Cal-Mag. I'm going to start out giving it every other watering. Should I give it every watering or every other? Also plants 1&2 have started pre-flower. I spotted some white hairs on the main stem of each.
