Yellowing on older fan leaf

ItsGrowingOnMestarted grow question 3y ago

Hey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Slight nutrient burn on the tips, otherwise it looks fine. Yellowing is caused by lack of Nitrogen. It is an easy fix and can be fixed in one feeding. The brown spots could be very early signs of Manganese, however if it isn't fixed by your cal-mag then flush and re water with 6-6.2 ph water. All things considered, the plant still looks good.

Lower your feed.. Maintain a steady PH (water & nutrient ph should be similar.) I c burn. So, I'm thinking its not a lack of, rather a PH

How’s your ph been? Could be some ph fluctuations or she could also be a lil hungry.

Why do I have rapidly spreading yellow on my leaves?I have this yellow spreading on some of the larger leaves and it's moving super fast. Please help. I've done research and it says it's a deficiency, mostly likely cal/mag. I added that and it got worse, now I'm thinking nutrient lockout? The pH is fine. What do?!

CalMag or something else?Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary. Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse. Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?

Light green tops I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.
