Hey, bro! 👋 At this age, she needs more phosphorus and less nitrogen! Keep the ratio A:B 1:3 and she'll soon gain weight in her buds! You'll see! 👌😇👍 Good luck, bro! 👋

Super soil needs activation?
There are plenty of nutrients in my supers soil. However I heard that the problem might be that the soil isnt "activated" is that logical? Thus need to add organic ferts? I am trying this, but I'm sure the super soil has months of nutes in it!

Yellowing and dry/brittle leaves
Hello all, I've noticed the leaves are starting to yellow and some are getting quite dry/brittle. Is this a sign of overwatering or perhaps nitrogen deficiency? It is on the same watering schedule as my other plant which looks healthy but obviously has different genetics.

Deficiency or light stress?
I start by saying that the light was not close enough to cause stress imo.. was about (30cm) of distance from this plant. it seems that it is more a deficiency in my opinion but I don't know exactly which one.. What do you think about that?
