I think i have nutrient lock out but don’t know how to fix it it, its 3th week of bloom and its an outside plant. Its getting colder 9 degrees C at night and around 20 at day. Its been raining a lot recently maybe that has something to do with it.

Pic 4 shows a typical leaf that is growing outdoors with cold night temps...........it is not a deficiency issue, just an accumulation of pigments (anthocyanins), much the same as how leaves change colour in fall before they drop off the trees.
Nutrient "lock-out" in the true sense, does not occur unless the soil pH is below 5.5 or over 7.5.

last photo reminds pests more. first few lack of phosphorus and/0r cold temps ( doubt cold fade could be so obvious so fast, especially while having days in 20+). my guess.

Brown spot on leavesI'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis.

Dark brown edgesHi. I need some solid advice as to what could be causing my lower leaves to be turning dark brown on the tips and edges. When looking closely, the browning has a bumpy texture and what looks like a fine, grey powder. Excess, deficiency? IdkWeek 8

Deficiency?Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?4y ago

Yellow and purple leavesI stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?Leaves. Color - Yellow
