looking at the diary I see that you’re not giving any nitrogen... the only thing it’s getting is from the cal mag... so I would start using a biogrow, the plant at this stage needs quite a bit of nitrogen I would increase the cal mag a bit, on some leaves there are some warning signs for the water the important thing is not how much you give but if you let the soil dry I saw that you added some worm humus that’s great too but it seems to be depleted the leaves are a bit light green
