just got a preflower. should i use tigerbloom bigbloom and opensesame together?

for my next feed should i use all these together? sounds a little hot so i want to make sure?

yes you can use them all. when i started using the solubles, i got a little nute burn.
i use the soil feed chart. start out with 1/2 strength or less of the liquids and 1/8 teaspoon or less of the open sesame. and see how they respond. feed every other watering and plain water every other. as they get older up the strength slowly. just my 2 cents.
