Hi.. ive just switched to 12/12 and my bloom nutes are still in the bloody mail which should be here anyday hopefully. In the meantime should i be topping up with fresh water to flush the old nutes? Or top it with veg nutes while im waiting??
Flushing is not needed unless you totally overfed your plant.Feed veg nutes until the bloom stretch ends,then start the bloom.You can mix them if you want, but I've never noticed a difference.
