Hi, Newbie here, I got Auto Candy Cane, and she is at day 38 from seed. I just notice a few yellow leaves at the bottom. It looks like Nitrogen Deficiency, but I am not sure. I did some research and found most of the Nitrogen Deficiency happens at the vegetative phase, but I am at the flowering phase. I am just wondering if it could be Potassium or Phosphorus or both Deficiency .
I fed her 2ml CalMag, 2ml Mirco, 1ml Gro, 2ml Bloom with half tsp of Molasses on day 33, and PH between 6 - 6.5. And I gave her PH water on day 37
Here are some pics. All the input are appreciated. Thanks

Magnesium deficiency. Not sure what brand of CalMag you're using but I believe most bottles are 5-10ml doses. https://www.mrgrowit.com/single-post/2017/11/14/Magnesium-Deficiency-in-Cannabis-Plants
I am using General Hydroponics CALiMAGic mix with overnight tap water. I will increase the calmag to 4ml next feed. Thanks Mr. Grow. Love you videos.
Might be locking up. Check your soil ph.
Ya, i tested the run off and i think i got PH blockage, its around 5 - 5.5.
Should i flush the plant or increase the ph to 7 for next feed? I usually ph around 6 - 6.5 for feeding and watering.
Yep same thing happened to me and everyone told me to throw more nutes at it because I'm not feeding enough. Now I'm in week 6 of flower with a terrible looking plant.. Always check ph first! Your soil is now way too acidic and the plant isn't taking in any nutrients. I would flush it real good with 7-8 ph water until the run off is back above 6.0. The ideal soil ph for cannabis is between 6.2-6.8, so continue using 7.0 ph when watering and feeding until you get back to the sweet spot, 6.5. If you're still having trouble getting back above 6.0, you can scratch in a teaspoon of dolomite lime for every gallon of medium one time. Good luck!
