heavy feeding on the bottle said 3tsp per gallon so i cut it in half but how often should i use it every feeding every other?
I don't use Tiger Bloom but most FF liquid ferts say that heavy feeding should be done at most once a week. That is a heavy feeding and then plain water for the rest of the week but I only use the bottle as a rough guideline. Check their site if your not sure though.
start off with a quarter of what they recommend and see how the plant does. it's always easier to give your plants more nutes than to correct after they've gotten burned
