Why are my fan leaves turning yellow during flowering?

Problem: A cannabis nitrogen deficiency will cause the older, lower leaves on your plant to turn yellow, wilt away and eventually die. If the yellowing leaves are at the top of your plant or the yellow leaves are mostly new growth, then you probably don't have a nitrogen deficiency.

Consequently, is it normal for fan leaves to yellow during flowering?

If the leaves are turning yellow during the final weeks of flowering, this is perfectly natural. Your plants are simply diverting resources to bud growth and letting the leaves die off. This is a good thing. But if the yellowing occurs early in flowering (or even during vegging), it is probably something serious.

Also, why are my fan leaves turning yellow? Well, cannabis can only uptake nutrients when the soil features a slightly acidic pH of 5.8–6.8. If the growing medium is too acidic or alkaline, plants will begin to starve. Eventually, nutrient deficiencies will take hold and fan leaves will start to become yellow in appearance.

Additionally, should I remove fan leaves during flowering?

Yes you should – but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.

Can yellow leaves turn green again?
