The Fun Deficiency Game!

[PaddyIrishMan]

Hi All!
So my Dinafem Auto Blue Cheese flipped just around christmas, was away for a few days and the two in soil (2 others in coco autopots) We're almost dried out and looking yellow. Temps were also were very low 55-60ish, they never get above 70 here.
I don't think it's a lockout cos one of the two in coco also shows signs of it. So i've narrowed it down to cold or a deficiency? (The drying out definitly didn't help!!). Such a shame cos before the christmas madness they were all a sea of green.
Anyway, let the games begin!
Thanks and good luck with the guessing

Looks like cal mag deficiency to me..

I believe it’s cal/mag also

I was wondering about cal mag only out of two I have in autopots on the same rez one is suffering while the other shows no signs at all. No chance it's the cold?

Not sure if you have the pots sitting on a cold floor and the drop in temps causing it. But if you could fill out the form with the info needed might be able to help give you a better answer to the problem.

looks like calmag, but micro-nutrients as well. You need a foliar spray, and hope the coco holds water and is still ph'd.. I have seen people not recommend foliar sprays in flower, but I use them. I just make sure not to spray buds.

Looks like a combo cal/mag and down turned leaf tips..they need the works. They may look crazy but might bounce back and push on. Need to look at more pics.
I like my temps 75 ish

Just playin along, this amateur says calcium deficiency due to the cold also phosphorus deficiency due to ph.
Ignore!

Paddy-- mostly it's the low temps, but the dry-out made matters worse with root damage, and possible pH drift into trouble zone,... But cold messes with uptake and transport of nutrients, along with causing low transpiration rates... that brings the flow of nutes to a near halt alone.... So, I see mostly P defc (large necrotic patches), yellowing,.... get those temps up constantly, feed a root tonic to them too,... you can foliar treat as well with a mild nute solution, it's still early bloom,.... tell me what you have- ... otherwise it's just wait and see how they recover,...
