Thanks Bricktop, I will see recheck what the bottle says again and definatley do some more studying. I appreciate your help.
Feeding nutrients is of course important but feeding 'more' or feeding 'more often' will often result in killing your plants with kindness. 'Just enough' is all that is needed and depending on the strain the plant's requirements and tolerance levels for differing amounts of nutrients will vary to some degree or another.
Always remember that some strains are heavy feeders and some are light feeders so there is no singular 'correct' ratio or amount to feed at any stage of growth that will give all strains all they need without giving them too much . Strains like Blueberry and ones crossed with Blueberry are nutrient sensitive and they will fry to dust if fed what would be normal amounts for some other strains.
Also remember that just because someone was capable of getting a job in a hydro store, or even opening one of their own, does not make them a botanist or even a skilled 'herb' grower. They will push what they sell and in particular they will push what they will make the most profit on and while doing it they will tell you it is the very best of the very best.
Good luck .. I hope all works out well for you and your 'lil 'uns.'
