I’ve been seeing a very slow development of what appears to be a calmag and nitrogen deficiency? Leafs (all) on 1 plant are very light green with darker stems. Now, it’s started to spread to the otherI did some research and think I’ve found the problem, but will call my hydro guy tomorrow.
what I believe is happening:
Veg+bloom RO/soft water nutrients are formulated assuming a PPM of 150 (so, not RO)... I’m using RO. SO, there isn’t enough of either calcium, magnesium, or nitrogen in the mix so I added calmag to my rotation. Even then it didn’t seem to help. Found
This perfect doc (love rqs site) and it gives a breakdown of what PPM is ideal for each phase of growth. Checked my PPM and it was sitting around 800 and should have been 1050(ish). So, I added some Stackswell (family of products with veg+bloom from hydroponics research) and got it up to 1063. We’ll see how they look tomorrow. I hope they green up, don’t want to lose another plant.
Other than that, buds are forming and getting frosty!!!
