Argh! I’ve changed so many things at once and now I’m kicking myself…
First the changes, then the issues…
Got a new lighting setup from Pacific Light Concepts. This is the only change I’m feeling good about. I built an 8 strip array and I love it!
I’m growing two, new to me strains - Big Bud & Gold Leaf from ILGM.
The last change is the one I’m most uncomfortable with… Growing in Coco in stead of ProMix.
I buffered the Coco in CalMag per “M.J. Coco” and have been following his feed chart/pH/PPM recommendations. As you can see I’m have nutrient issues. I’m thinking it’s either Magnesium or Nitrogen. The leaves are all pale with dark veining. Yesterday I returned to the nutrient schedule (GenHydro recommended chart) I used in soil. I set it up to 620 (PPM)/1270 (EC)/5.7 (pH). Checked about an hour after watering and the girls were looking a much healthier green. I read the run-off at 550 (PPM) with a pH of 6.8. I assumed the pH change was because of the Coco holding on to the nutrients, but was surprised at the how high of a jump it was. I haven’t read my run-off in the past.
So I’m now confused about what to do next. I figured the new light would make for hungry plants, but I didn’t think they would be starving…
So I’m hoping these pic are enough for figuring out if they need more Mg or N.
