Strange leaves

Thank you everybody!😊

To much nitrogen , after stretch you really need to cut it back and just give more potassium and phosphorus . They just need a small amount of nitrogen to keep going after the stretch I have found.

That’s normal for real OG strains to have a 3-5 finger. And it looks like they are going to purple out on you too. Looks about right! Good luck! ✌️🌿💨

Just to be clear this locks out absorption of other key nutrients and can cause looks of deficiencies

Overfed N.. probably overfed in general

Without a diary, it's very difficult to give you any advice that's more than just a guess. In general, small yellow/brown spots usually indicate a calcium deficiency - but you need to figure out WHY you have this as your nutes will usually contain sufficient quantities of calcium... I look at the leaves that are curling down and that MAY indicate too much nitrogen that COULD produce a lockout of calcium ... but then so, too, could a pH that's not at the proper level (6.0-6.2) for maximum calcium absorbtion. If it's not a nitrogen toxicity (rather doubtful in my mind) or a pH that's not where it should be (more likely), then just giving it some calmag might help. Best advice I can give you is to start a diary. When problems/questions/issues arise, diaries help us help you... it becomes a win-win Good luck....

If it's under a bunch of foliage, the leaf may be dying off due to lack of light. If it gets plenty of light, it may not have received enough nitrogen during its pre-flower stretch. Cannabis plants, "stretch," for the first 3-4 weeks of being under 12 hours of light and 12 hours of darkness. So, you have to make sure to give them enough nitrogen to make it through the stretch, as well as the rest of flower. It can be tough because every cultivar is different, just like every phenotype. It could also be chalked up to basic fade, which the plant does towards the end of it's life cycle. Fade is when the plant basically starts eating itself.
