I was wondering If I can use a 10-15-10 plant food on my baby, i havent started using it yet because its still early in the veg state. Am I good to use it, though,
Thanks a lot man, that was really helpful.10-15-10 is certainly not the best choice of veg nute, for flowering it would be ok but not great. For veg you want to aim for a 2:1:1 ratio, which would look like 10-5-5 NPK, it doesn't have to be exact but at least in the ballpark. As for flowering, aim for a 1:2:2 ratio, which would look like 5-10-10 NPK. That's why a lot of growers (especially hydroponic growers) go with a 3-part hydroponic nutrient, as you can custom tailor the ratio you want for a specific growth phase.
Here are a couple of basic nutrient ratio rules:
More nitrogen than potassium promotes vigorous vegetative growth
More potassium than nitrogen promotes flower and bud production
Phosphorus is much less important in the vegetative stage than it is in flowering
As much as phosphorus is important during the flowering phase, don't overdo it. A 1:2 or 1:3 (at the most) NP ratio is more than enough phosphorus during flowering.
