Need Help Defenciency

To start I have a LST'ed Cheese Auto that is in flower at the moment. Early on I had a Cal/MAg issue but it recovers really nice. But now I'm having some discoloration and it seems to be getting worse. I need advice on the cause of or solution to. To me it looks like some kind of deficiency but idk what. I haven't changed anything and I've been feeding the same cycle. Please take look at the pics and give any advice you can. Thanks.

Looks like u had some burn at some point but new growth looks good so ur back on track

magnesium def

add 1/2 tsp Epsom salt per 1 gallon water 1x and water it in

spray with 1/4 tsp per gallon 1 or 2x ......3 days apart

and 1/4 tsp Epsom salt evey other watering there after from now on



also
stop pulling your fan leaves off... its not helping you... if theyre healthy leave them alone... if theyre at the bottom and not getting enough light go ahead and pull them

late into flower / like week 8 of 12/12 you can start plucking fan leaves to help increase air flow and by then the plants usually begin to shed the fan leaves anyway

think of your fan leaves like solar panels on a house that collect the suns rays for energy....
you ever here someone say, gee wiz I wish my home had less solar panels! nope!
the more solar panels the more energy the system can produce and store

same for your plants

If you were stripping leaves on an AUTO , you can stress it or stunt it.
Autos are plug and play ....
