RQS Royal Runtz, Sweet ZZ & Joanne's CBD

Week 3 was a bit of a challenge. My pots arrived a few days too late, so my young plants had some extra days to grow more roots before transferring them to the large pots. Their roots were already well developed and they dried up very fast so I'd preferred moving them to cocos earlier, but I had no choice. Some leaves were already turning light green/yellow so it was really time to give them growing space and nutrients. Finally at grow day 18 I got the pots and transferred the plants to the 25L pots. At the same time I trimmed the lower leaves and FIMed all plants at node 5. Sweet ZZ far left, far right and front left are Runtz, front right is Joanne's CBD. The medium was pretty dry and the PH a bit too high, so I watered it well after planting. I noticed the EC kept dropping. The day after the plants didn't look 100% happy. Maybe too wet, so I stopped watering for a few days. Or too much light intensity, so raised the light to the max. Some plant's leaves were too light green and curled as if PH was too high. I read about cocos buffering some of the nutrient's calcium, so added 1/3 of the recommended dose of calmag. Surely my plants are looking much better every day, water PH and EC are stable. First time I try cocos, so this is getting used to. But I'm getting there.
