yes i know all that.....it's true that PK:13-14 is a supplement and it is meant to be used in conjunction to the regular fert.....BUT....the soil i use is a special one.....it is made especially for plants that produce flowers.....for example....i did not use any ferts during vegetation but twice....not that the plants showed any defficiencies, i was just anxious for them to grow even more.....this particular soil i bought is meant for geranium plants, it contains micro and macro nutrients, organic material.....ph balanced around 7 etc.....so far so good i suppose....now, the only thing that could cause trouble to my plants is not any food deficiency (that i can deal with easily)......my only BIG mistake is that i have them growing into 2 1/2 gallon pots.....they might get root bound but then again i hope they will not as i water them almost every too days with a little water each (around 150-175ml) so as they do not flush from the bottom and loose any nutrients......i have even put some nails in each pot so as to have Fe at any time available....i've read that they need it especially during flowering.....next time though i will put them into 5 gallon pots and flower them when they reach 12 inches....this time they went into flowering when the biggest was almost two ft.....anyway, i am almost two and a half weeks away to stop feeding them any nuts at all so i guess everything will go as planned......today is day 23 into 12/12.....with lots of TLC I show them they will make it as planned to harvest
