Is this Potassium deficiency? If not, which deficiency is it? Day 99, 39F. Leaves getting a bit yellow, while having browning on the tips.
ezgrows4anoobstarted grow question 2 years ago
I know that it is not overfeeding, and I also know that it is not lockout. PH could be off, but I do not think so. So, what deficiency is this?

Hot dam them are some nice looking plants!
typicality potassium gets yellow on the edges vs purple. purple coloration can also be caused by cooler temps and end of life, If its brown and crispy and curled up it normally means its over fed. Given that potassium is mobile I'd expect this to be on the lower growth first vs top. I feel this could be lacking a bit of Magnesium but could also be natural fade as your coming to the end of your grow. If you wanted to you could add a bit of epsom salts into the next water and call it a day. Little goes a long way, 1/4 teaspoon per plant for the size of them and monitor if it continues.

Just a few observations:
- Burnt tips, usually too much K
- Purple leaves, often not enough P
- Yellowing, not enough N
Suggest checking (including the root zone) for pests and/or pathogenic fungal infections first. Then consider adjusting your nutrient element ratio based on the plants feedback.

I agree with m0use and growinggrannie, does look more like natural fade then a lack of nutrition. Your grows looking good and doesn't look far from being finished so I'm going with they are naturally fading.

High bro, your plants are almost ready but they can still fatten up those juicy buds a bit more for the next weeks. Make sure that you give your plants enough phosphorus (P) and potassium (K) during the last weeks. The plant needs those nutrients to let those buds get nice fat and juicy for harvest!
You can use a basic blooming nutrient together with a PK-Booster like PK 13/14 For the last weeks. pH 6.2 and EC 1.6 Devide the EC by basic blooming nutrient EC 1.0 And PK-Booster EC 0.6 So together EC 1.6
Enjoy the rest of your grow and the harvest!

You're right - it's neither overfeeding or lockout.. I'm going to agree with m0use here suggesting that what you're seeing is just the natural fade of your plant.. You typically are not going to see deficiencies or excesses show up first on the leaves of your buds... No need to flush (unless you are getting them ready for harvest and subscribe to the theory flushing is mandatory which it's not!).... At this age, I would be getting ready for some time in trim jail!
Good luck!

After reading your diary a bit - I think you stopped feeding too early. Or didn’t feed enough on the last top dress?
I’m not an amendment grower so I’m not going to speculate much beyond that..
PS - Can we stop with the running to google for a copy and paste from a website folks? Or if you do - don’t be disingenuous about it. Let it be known that’s exactly what you’re doing for your answers

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing.
I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"
