Phosphorous Toxicity or Temperature Shock

So there are some ladies outside, I'm sorry I don't have pictures right now, but here we go.. So conditions: about 9000 feet in an area w birch trees around so tree roots could be interfering, but temperatures get down to about 42 degrees every night. I made a 5 gallon Jamaican Bat Guano tea and it wasn't shaken up when someone added it to the plants. Now they are beginning to turn yellow,

Would you believe that it's the?

a) temperature b) phosporous toxicity or c) tree roots D) your own thoughts....???

Let me know, thanks..

They are planted outdoors at 9000 feet? Hard to finish.

Starting to turn yellow could be a lot of things so try to post some pics.
