Sick Auto Mazar

[Grim Reefer]

Hi dudes! Seem to be getting this problem with every plant and im not sure if its cal?mg?? thought i was preventing cal/mg by using molasses in every feed.
The two mazars had a proper flush over the weekend just incase it was nute lock out and started them on a half strength dose of nutes again.

Phosphorous def. What are the numbers on your nutes? Try and give them higher doses of phosphous also some nit and potassium.

Seems like Ca deficiency to me. I didn't know there was Ca in molasses.. But I guess adding some real Ca should do the trick. Also the temperatures seem too high (see the edges of your leaves turn upwards? That's a sign of plants closing their mouths to save water).
A phosporous deficiency shows like namvet25's picture, that's true. But there's a small difference: notice the clear 'rusty'/organge marks on the leaves of Briain's plants; this shows that there's a Ca deficiency and not a phosphorous def.

Cal/Mag and P deficiencies often go hand in hand, so could be a bit of both. How's your pH?
