Is this a cal mag deficiency. 24 days left in flower of a 9 weeks. That's the top of plant.. leafs going light in the middle of the plant. Be doing a 2 weeks flush in 9 days. So do I just leave it or try and treat it.

First off , Jaysus man that's some long ass title of topic you got going on .

 

Can you give us a bit  more info , like what strain it is , what medium it is , environment readings , size of pot,  how often your watering/feeding, what your feeding? 

 

Lets take it from there 

 

oh and a shot shot or two of the whole plant is needed .

Looks like something you've spilt on the leaves that's subsequently dried out. At least that's the appearance. Even if it was Calcium deficiency (evident at top of plant unlike Magnesium deficiency) with so little time left to go I'd be unconcerned. This was my plants late into the flush suffering from lack of Calcium, starts with brown rush spots followed by a yellowing of the leaves. Note leaves out of direct light are relatively unaffected (further down the stem). This grow turned out lovely.

 

So if you haven't accidentally spilt pot noodle on it, if it was Calcium deficiency (which it doesn't look like) you'll be long finished before you even get close to how my plants looked :yep: @Newtothisjb Any remedial action taken at this late stage will have little effect.

The bottom pic is a different strain which I'm thinking is to much nutes.... I'm in coco 15l pots watering every day 1.2l 1.4l till it runs off. Ec is now at o.8 was at  1.0 last week.  The top pic is a different strain started at same time. That one the leaves have all gone lighter on the bottom and middle of the plant
