^Those will work just fine. Alot of guys use them, with great results. Actually, just about any type of nutes will work, as long as you mix it correctly, adjust the PH, and have the right NPK ratios for veg, or bloom. The best advice I can give you, is to start weak. Many times I see guys feed more, because they assume the plants will grow more, like people or animals. As tempting as that is, avoid it, it'll only hurt them. Start weak, and in the meantime, start reading up on deficiencies/overfert, and the symptoms to watch for. Learn to recognize what your plants want, and you'll be a successful grower.
P.S. The feeding schedules on the bottles, almost never work out. Don't trust them, unless you know for sure that they're tailored to your specific grow. If you must use them as a guideline, start with 1/4 their recommendation, and work your way up from there.
