So I have a lady that has been growing in a 1 gal pot w/ FFHF and was growing great with no slowing down in sight. I transplanted her into a 3 gal pot w/ FFOF. Around a 8 days after the transplant I started noticing leaves Turning yellow on the tips which eventually turned to brown spots which then took over the whole leaf ultimately killing the leaf. After my research I’m not sure if it’s a cal def, nite lockout or what! I’m Not thinking it’s a pest as only one plant has these issues. Thanks in advance for any help!
