Northern light auto, LED 450W

19.3 I normally try to update the diary two times a week, but this week was not much happening, so this is the only update on this week. During this week I put the plants to large pots and after potting plants to large pot I accidentally over watered the plants, which resulted to few days of halted growth. Now plants seems to have recovered from that and beginning to grow again. In over all plants looks healthy except one has signs of iron deficiency. I tested soil PH, which was 6.15, so it's OK. I'. leaning to think maybe yellow leafs are the cause from the stress of over watering and changing pots. At the begging of the grow I had some problems with humidity, which some times was as low as 20%, now I bought a humidifier and have been able to lift humidity to 65%, where I'm trying to keep it for now.
