White Crack - Mephisto Genetics

Another week of nice steady growth to report :) They have taken to their new homes well. They were transplanted into 15 liter auto pots last week, and are currently being top fed for ~2 weeks to establish before switching to the auto pots on. Nothing really remarkable to report. One of the plants has a slight yellowing of the cotyledon. I'm not really concerned, as one of the plants on my last grow had the exact same thing, and it was fine. Just wondered if this is a common thing, some random quirk in the genes, or maybe something about my setup? Who knows, but the plant seems fine and is flourishing regardless. I'll let the plant tell me if something's up. One plant is very slightly behind the other in terms of leaf development, but that's really just being picky because they are both coming on really well. For the first 2 weeks, they were only fed PH'd water with a little rhizo and calmag. I have introduced some proper nutes for the first time today at around quarter strength. With Coco A+B now taking care of the Ca and Mg needs of the plant, I've dropped the CalMag additive, and will now likely only use it if I begin to see any deficiencies. I kinda get the impression that CalMag get used a lot when it really doesn't need to be.... but I don't really have enough knowledge to know if there are legitimate use cases for it to be fed for an entire grow like I've seen in some diaries, so I could be completely wrong on that. I will see how they respond to the nutes, and dial in accordingly over the coming weeks. I want to keep them at a fairly low level, ready for switching on the auto pots. After top feeding for the whole of my first grow, I am a little apprehensive about salt build up in the auto pots. But damn, they seem to produce good results, just gotta manage that EC and not let it get out of control. All in all, well happy with the progress, coming on nicely.
