If you have some grandma's molasses laying around you can add 1-2 tablespoons/gallon until you get your bloom nutes. It has a little of what a flowering plant needs, not everything but it will help and it has carbohydrates in it. The straight water will help to flush out any toxic salt buildup in the soil from the nutes. Make sure you water enough that you have plenty of runoff and that you only water when the pot is light. Might I suggest, for a cheapy solution getting jungle juice bloom. It is only $7.50 for a 1 quart container and its pretty good stuff. Its from advanced nutrients. It is on htgsupply. Np for the tip, that's what I'm here for.
