I have 2 White Widow plants that are yellowing around the outer edge of the leaves and I’m not sure exactly why. Plants are on Day 53 of Veg. Soil is 50/50 mix of Fox Farm Ocean forest & Happy frog. Started in solo cup for 18 Days, transplanted into 3 Gal pot on Day 19, top fed with Dr Earth 4-4-4 on Day 40, and transplanted into 5 Gal pot on day 49. It started with one plant and then the second plant started showing the same issues. The issues has been at the top of the plant the entire time, so I’m pretty sure the
deficiency isn’t Mobile. I have 2 GDP plants in the same tent & on the same schedule and they are perfectly healthy.

Looks a lot like copper deficiency. https://www.growweedeasy.com/cannabis-plant-problems/copper-deficiency Interested to see what the pH and PPM of the runoff are.
I understand the position my friend. Will help as much as possible.
It can be frustrating. I'm constantly growing multi strain grows and as much as I hope I can run them on the same schedule, same amounts, etc, it never goes that way. Right now I have 4 that are same age, same medium, same room and one had deficiency, then I over did it and had excess issues. I've had same strains react differently before. Growing has its ups and downs but it's a labor of love.
If you flip them before finding and fixing the issue you may run into growth and other issues.
Strains can be different in reactions. Some of those leaves are pretty advanced and at that point the appearance can be blamed on multiple things. Need to know the basics before knowing which direction for next step. The ppm and pH run off will give us an idea where to go. Also how often do you water?
I can try next time I water. I’m in fabric pots and what little run off there is just gets sucked back up. I know the soil is a little hot because I have 2 GDP plants Im growing along with these and they have a little bit of nutrient burn, but other than that they are perfectly healthy. Same soil, water, nutrients, and they’re fine. If it were a ph or ppm issue I’d think the GDP plants would also have issues, but they don’t
Can you get a ppm and pH run off?
