I got new food.. 2,5-6,2-6,3 .. This one had highest P in that shop.. Is it better than 3,5-2,3-5? And how big dose should i give her?
Yes, what you have is better than the other one. The directions for feeding should be on the package. Start with 1/4 the recommended strength and then work your way up.
^ you are right ICE. OP, my advice was given assuming that your plants were flowering. If they are vegging, go with the other fert. If they are seedlings, give them no ferts.
