Hello hello,
First indoor grow and something seems off with my GG4. Everything was looking great and then I started to try to train the GG4 and it started developing some brown spots on leaves see pictures. I am growing 4 types, bottom left is Gorilla Glue 4, bottom right is Great White Shark, top left is Geleto, top right is an Auto Northern Storm left over seed I had and put it in with my photo’s (I know bad idea ).

Anyway everything was going great until all the sudden my one GG4 started to develop brown spots and I also noticed a lot of purple lines on the stems. I was thinking both problems were related to Cal/Mag but don’t understand why this one could be suffering a deficiency when the others are not from same nutes. But then I thought about it and remembered taking a clone off the GG4 and also doing some training of the center stalk to do a bit of SCRog... Could that have caused it? It was the day before it first appeared.

Hoping someone can either tell me they are fine, or help me figure out what the hell I did wrong and how to rectify it...

Last question: I am about 8 weeks in from seed and they seem a bit small, is that my imagination, or should they be bigger?

thank you in advance!
