the nutrient solution you have highlighted is know as a balanced vegetative primary nutrient.
it will be fine on your plants for the veg stage - but just incase keep an eye out for any possible nitrogen deficiencies, as is usually best to feed a nute that is slightly higher in N than P & K.
Hey man how's it burning ? I'M growing outdoors I use 20-20-20 miracle grow for growing and 10-52-10 for flowering works great . Just make sure you don't overfeed any
plant.
