I realized after you said it but on the bottle of big bloom it says for late vegging and on the chart I have it shows that you should use it from seeds and cuttings...whats up with that?
the only diff u usually see is in the ratios of NPK- veg have higher N and lower P and K while bloom has lower N, and higher P and K which is why so many who cut out the veg goinging into flowering are getting premature yellowing
