You can clearly see that the extra N took its toll on the Connoisseur grow. i am amazed at the results I'm getting using dynagrow at very weak concentrations, My girls in mid flower are completely happy at .9 EC, and the mature girls are coasting along at .5EC. at day 58 I'm showing a little yellow in the fan leaves as you would expect so close to harvest. I have not been adding any extra N to the bloom mix. I encourage everyone to have a go at running very low nute levels, I know I was pleasantly surprised. My buds look the best of anything I've ever grown.
HB has really sped up my learning curve by pointing me in the low nute level direction. I could have continued feeding at a normal 800 ppm and chased my tail trying to figure out whats wrong. I look back on feeding at 1200ppm, and getting signs of calcium and magnesium def. I even thought I had tobacco mosaic virus while burning my girls at "normal feeding levels".
Question for HB
I know you like to add the 1ml of grow to your bloom nutes to give a little extra N. I remember you commenting in one of your earlier journals that the lower leaves were showing some yellow and started adding N to correct this. Do you think that the yellow may have just been from low light at the bottom of the canopy, and not a N deficiency. My grow was a little less dense than yours with just 3 plants under the 600watt, and never showed the pale undergrowth.
