[Dwight Monk]

Also what type of light, as advice varies on that....and yeah pics always always help

 

[Sidvishus]

Could be just senescence, or maybe because you've upped the photons the plant needs more nutrients to keep up.

looks pretty normal, plants are using up the N. Some strains yellow more in flower than others.

40 of each A&B to 20 ltr water

this.

in flower so simply pulling what it cant get elsewhere. it's a bit deep for senescence for me though. i'd like the buds further along if it's that deep. so nutrient side.

Ye looks pretty normal to be honest & if you are a new grower freaking out about the extensive yellowing in flowering !

Well that is just growing for ya.

Don't treat em all the same bit like human beings really... OMG did I suggest plants have rights ?

Perfect example of a plant running out of available nutrients. No issues just no food.
