Weird stuff going on 4weeks flower.. need help!

[ChoppedGreens]

Hi guys, I have some plants that will be 4 weeks flower this friday. They are in Roots organic soil (camo bag) and I don't know if I am seeing deficiency or toxicity!
The only nutes I have fed is (15ml Pure blend pro bloom, 5ml calmag/gal)
It isn't heat or light stress either, because temps never get above 80 and the light is 7" away

water and soil PH are both and always between 6-7, usualy stays posted at 6.5

Haven't you already posted this and been told (for one by me) that you're seeing an Mg deficiency.

Starts with discoloured blotches, leading to leaf tip curl up, leading to overall brown spots and burnt looking patches, leading to papery white/yellow leaves.

This late in the game you're not going to be able to correct it.

Look at the info in the pic and apply which ever cause you think might be attributing to it.

Deff mag deffiency. I do disagree that there is nothing you can do! There plenty you can do to stop more retardation of the leaves. Up the cal mag to 7 ml they need more in bloom then in veg. I would cut off most of the really dead stuff( leaves) it's only making the plant think about repairing it self. Your gonna have diminished harvest cause of all this stress but your buds look okay to me so far.

Sorry my bad.

Didn't notice the 4 weeks in flower part.

Treat as per deficiency directions on the help pic.
