Nutrients for preflowering stage

One aspect the previous posters fail to address is that you're growing an auto and "flipping" is totally out of your control. You can expect it to transition over the next couple weeks. I generally don't go heavy on veg nutes on autos, some just give bloom from the beginning. A lot depends on what line you use. Flora Trio for instance uses some nitrogen even when mixed for bloom. If your soil isn't devoid of nutes, generally it's enough to carry an auto to flower, then you can focus on bloom nutes.

Hi fellow grower, the preflowers are just a sign she is female. Not the start of flowering stage. Some start when they switch to 12/12, others wait till pistols appear at top. Signalling flowering. She is looking health so keep it up buddy! Good luck and happy growing

I personally give a little bloom nutes when I first flip to 12/12 to promote some root growth while they grow rapidly. I add 200 ppm and cut the veg nute back 200 ppm. I only give them one feed like this, then back to straight veg nutes up until button size buds have formed. Then their first feed with bloom nutes I mix half bloom and half veg nutes for their first flower feed, then to straight bloom nutes after that. Hope this helps. Cheers

Creo que es muy temprano para el pk, yo seguiría alimentando el crecimiento y el pk lo usaría para la floración
