my firsy ever grow im really new to it all to be honest im gunna set up in my cupboard 400w hps and one auto pot and a fan blowing is that okay how much nutrients do i add to a 47litre tank ? and when should i add the nutrients to the tank ??

yea if you want them short and stocky looking you can top them...as far as the yellowing it could be from a couple things ... 1) Lack of nutrients ..2) the plants are too close to the light...im still a beginner grower as well so those are my suggestions.

also i just topped them...and there omly three weeks old did not know when to do it friend told me to top it if i went them short.....is that true.....

whats up sneaker head maybe you can help me one of my plants leaf stems are turning yellow do you know anything about that what should i do.....
