The other geniuses have no answers....come on guys its an easy one. And I know you are not more stonededer than me.
Its cannabis and theres 2 minerals she loves to pig out on. Not N P or K. One would definitely help the stunting in the bigger one and possibly the curling too. The other would likely help with curling and the not quite right shade of green. Both can be found in dolomite which....wait for it....helps correct acidic pHs. Which can lock up lotsa stuff leading to visible symptoms via complicated pathways.
so what do i do to fix this im confused its my first grow as well

The bigger plant, if it was mine, I'd top dress some dolomite lime. If cant get that, liquid cal-mag and pH that solution to 6.6-7.0 as best you can.
The smaller ones, just use good water source till bigger.

okay ive got cal mag also been making sure when i water it or feed that its ph is between 5.4/5.8 and is it ok to mix calmag and water at the right ph for the 4 baby autos cause they dont need nutes yet i was told
