Growing a forbidden fruit plant and many of the ‘lower’ leaves are showing this on the leaves of one strain. I’m growing outdoors in 10 gallon pots using a pH of 6.3 to 6.5. Only other nutrients are feather meal for nitrogen. I also used MorBloom 0-10-10 recently as a PH lowering addition.that is a new addition

Which Nute do you folks believe it is?

Thanks

If it's nute burn, there's no way to tell which specific nute is doing it - only that you need to lower PPM's on the feeding or the soil is too "hot". That being said, it looks like a possible calcium deficiency to me. Are you using R/O water and, if so, are you adding cal-mag?
