Any of those three brands of nutes will work. All three are well made and will get the job done. I use the BMO, but just because it's local for me and the price is right. Just feed them reasonable. Start at 1/2 the recommended mixing strengths, then work upwards. Tag two plants and feed them at a slightly stronger mixing strength, to determine if they are light, medium or heavy feeders. All strains are different. Some eat like super models, others are nutes hogs.
.
If the ones being fed the heavier feeding schedule show no signs of nute burn on leaf tips, then kick up the mixing strength for your other plants. If the two being fed heavier, do so signs of nute burn, skip the next feeding for them, use plain water or compost tea instead, then put them on the same feeding schedule as the others the following week.
.
By always testing two plants, you avoid burning or shocking the entire tribe all at once.
