During vegtative growth, the plant's nutrient and water intake changes. Transpiration is carried on at a more rapid rate, requiring more water. High levels of nitrogen are needed; potassium, phosphorus, calcium, magnesium, sulfer and trace elements are used at much faster rates...
As soon as light set to 12/12 cycle which signal MJ to start flowering. Growth paterns and chemistry change. Stems elongate, leaves grow progressively fewer blades, cannabinoid production slow at first then accelerates; flower formation is rapid at first then slows. Nutrient needs change as growth stages change. Plants focus on flower production rather than vegitative growth. Phosphorus uptake increases to promote floral formation."

Glad to see you have a book...........lol Jorge is a good guy.
I have several copies of his stuff. Good for nubies for sure but not for advanced growers. It's just average basic but everyone needs to know them.

But you did not answer my question at all. All you did was copy paste. Do you understand what you posted at all? There is nothing in there about fine-tuning your growth cycle. Just the same general knowledge every one say's, very general and safe. I'm talking about fine-tuning you grow so the plant has the minimum amount of stress. The plant uptake is improved; the plant can process more nutrients and grows faster and healthier when the stress is less. There is so much more to it then just one paragraph.
From that it sounds like you can grow with miracle grow too.
