White widow feminized.
coco/soil/worm castings mixture.
18/6 light schedule
Nutrients are added every other watering.
using general hydroponics. Aprox 1ml per L
Using CaliMagic aprox 1ml per L
spider farmer sf 2000.

out of my four plants this is the only one showing these signs. They all get the same water.( once top inch or so is dry)

Does this look like a toxicity or deficieny?
Any information is appreciated.

Much love
Andy

That is a deficiency. For whatever reason, that looks like Cal/Mag problems. I always put them together, because they often happen together for a couple reasons. 1. Cannabis loves and needs them both. Some plants can't seem to get enough. 2. When you have nutrient lockout probs, they are both affected. Your pH could be too high, or your feeding program doesn't have enough. I always use some sort of Cal/Mag product. That's also the reason I use pH 6 water in soil instead of 6.5 like some do. If your soil drifts too high, nutes are not available to the plant no matter how much you use. Most folks don't understand pH as well as they should. It's measured on a logarithmic scale. pH 7 is 10 times more alkaline than 6. And 5 is 10x more acidic than 6.
Hope this helps.

Thank you! I think you were right about the deficiency. Doubled up on the calimagic and seems to be doing well. PH run off is usually around 5.9 to 6.2.
More pictures will come soon. They are looking a lot better!
