Sugar Leaf Yellowing Back to Front...

Hey guys,

I'm on day 60 with 2 high CBD autos from Dinafem. I've been watering every 3rd or 4th day and giving the plants a light dose of nutrients every other week.

About a week ago I noticed some yellowing on the sugar leaves, which has been slowly progressing from back to front. Some necrotic spots along with purple leaf edges are also present.

At first I thought it was sulfur deficiency ("yellowing on new growth from back to front") but after a dose of Epsom salts 4 days ago the problem has continued to worsen, so I gave the plants a light dose of nutrients along with seaweed extract/micronutrients this morning. Besides today's feeding, the plants haven't received any nutrients in 2 weeks. I'm growing in Roots Organics Soil.

I'm planning on letting the plants go another 2-3 weeks, so if this continues to worsen I'll end up with some yellow bud

Any suggestions/input would be greatly appreciated. Thanks!

I don't grow autos but what I see is a lack of N due to late stage bud development,u can't correct the yellowing already present by adding light dose N but u can prevent further brown out by adding N to the feeding

those yellow leaves won't make your bud yellow either because you dig inside the bud to the stem connecting those big leaves for a killer trim

Beautiful. Hopefully the light dose I gave them today will tide them over till harvest then. Thank you!

as long as your within a couple weeks of harvest some yellowing leaves are a good thing,I've been growing sea of green from clone to harvest in 7 weeks for years,which is similar to autos & my plants end up roughly 20% to 30% yellow when I chop from lack of N ,again a good thing,less green leaf material means less chlorophyll to cure out of the bud

your looking good,don't sweat it
