First grow in Autopots and Coco (Mephisto Sour Stomper & Strawberry Nuggets x SOH)

On Day 25 I think overall growth is ok but could be better. Especially when I compare those to my last grow. But I think I made some mistskes which lead to this. First of all before I turned on the autopots I watered with silica which I learned can lead to problems if not added first to the water and then let it dissolve for around 30 minutes. This lead especially to problems on the sour stomper where the lower growth got white spots on some leafs. Second is that I did add Calmag and Monomag because my tapwater contains almost nothing of it (3,5mg/l mag and 30mg/l cal). But Coco A+B from Plagron contain more than enough of it and theres no need for me to add more. Once I did realize that I changed the solution in my reservoir. I hope they will pick up pace soon. Besides that I think I gave them too much light because especially the SNxSOH grew really bushy. Despite not wanting to do it I removed some fanleaves from the SNxSOH to give the lower branches more light. In the retrospective I think this was also a mistake.
