mag def

i seemed to have a lil mag def i think from keeping my ph to low ive since corrected the ph im wondering when the def is over does the purple stems start to go away an turn back green

purple stems isnt magnesium.

magnesium is interveinal chlorosis

purple stems is P def. or genetics or too cold temperatures

well more red i guess an all the other signs point to mag yellowing of leaves between veins on lower leaves with rust spots ive been keeping my ph at 5 i dont have a meter just the liquid litmus getting a meter soon my nutrients are designed for a slight ph drift an i think ive just been keeping the ph way to low for it to utilize correctly im growing in rockwool i should prolly also state

so when the def is over if i have corrected the problem do the coloring of the stems go back green because thats what seems to be happening is the green is coming back an the purple is receding
