If this is only happening after veg, and during flower...likely it's either what you've transplanted into, (your soil mix) or you nutrients. Plants use phosphorous in veg too, so possibly would see signs early.

If there's no perlite or other ammendment to lighten-up the soil, your soil can suffocate the root system. The mud compacts around the roots, starving them of air and nutrients....and promotes root rot.

A good commercial soil (and perhaps some added perlite if necessary) helps avoid most of these types of soil problems, and using rose food (10-52-10) is a great way to overnute your ladies.

If you do some research, you would notice the NPK numbers on the package. Do yourself a favor, and check-out the normal nutrients most cannabis growers use. Fox Farms, Botanicare...to name a couple.

FF Tiger Bloom is 2-8-4. (given every week per instructions) The most I've ever given was a double dose, pulling the theoretical ratio to 4-16-8. It severly burned the ladies, and stunted them dramatically even at this low ratio. You are giving double this semi-toxic ratio, every how often...?

I'm with Mr. Clandestine on this one...1/4 to 1/8 dose, and wait a few days between dicking with it, or you'll end-up loving your ladies to death.

2% rice? Why? Was it composted? I'm pretty sure cannabis wont uptake rice without a hollandaise or soy sauce...but I hear butter works in a pinch. :jointsmile:
