Potassium deficiency or? incl.pic

[maystor]

Hey all,

My plants passed 6 weeks of flowering and are doing fine with the buds. However some strange colour appeared on one of my plants' leaves and only on its big leaves. I've cut down one of the leaves and here how it looks like.
Do you think its potassium defficiency or might be something else? I give ém nutes once a week with half the recomended dosage on the packaging. My fertilizer is 4-6,5-7

As I've said my plants have passed 6 weeks of flowering and are in their 7th week now. I vegged them for 4 weeks. 4-6,5-7 is the N-P-K values of my fertilizer. Still all other leaves look very healthy and green

Post some pics of the entire plant and the location where this particular leaf came from in terms of low or up high.

Help us help you.

I see nothing wrong with that plant. It is perfectly normal to have leafs turn during the flowering stage.

Grow room get cold at night? Looks like a cold temp induced color change. Nothin to worry about at all, in fact, many growers try to run a bit colder sometimes to get the purple effect.
