No, I would say it wasn’t too late. They can handle that in the short term; of course, each one behaves a bit differently, but if you counteract in time, they won’t suffer any, or any major, damage from it. She still looks good. ---

To me, that looks like nutrient burn. 500 PPFD wouldn’t cause something like that. The sun puts out around 2000 PPFD on a clear day, and most strains can handle that just fine. I’d stick to tab water for the next one or two waterings and see how the plant reacts. ✌🙂 ![image](https://social.growithjane.com/uploads/default/original/3X/b/6/b6485f370a3184f4879150581d8fae7092fdbd1d.jpeg) ---

@Lynx_361 I unfortunately have to say that I use All-In-Mix soil but haven’t fertilized it myself yet. I’ve only watered it with 6.5 pH. Because it’s pre-fertilized soil, that might be it. Maybe a nutrient surplus??? @herr_gruen I have now raised my lamp to 45cm. My upper part now gets 430ppfd and the lower part about 375ppfd. ---

PPFD is definitely fine, couldn’t see any deformed leaves. But what @Lynx_361 noticed would fit. Forgot that you use All Mix like me. ---

@herr_gruen The upper left one. ![1000043638](https://social.growithjane.com/uploads/default/original/3X/0/e/0e831704784be1dcb5197cd323a913d919473d06.jpeg) But should I flush all my soil now? Because all useful nutrients would be lost from the soil. I don’t necessarily think that’s the best solution. Or is it? ---

No, never mind. The tips are white and bending upwards, that’s from the light. Was that picture before you moved the lamp? ---

Yes, exactly. Now it’s at a 45cm distance and has about 430ppfd at the tip and about 350-375ppfd ---

What’s the temperature and humidity in your tent? ![Leaf-Vapor-Pressure-Deficit-VPD-0](https://social.growithjane.com/uploads/default/original/3X/7/d/7d57fb9a35974c758dbd4e517f0efcb7ca037917.jpeg) ---

Pretty much optimal. End of the 2nd week of the veg phase. Average: 24.8° / 55% - 62% works out pretty well. ---

I would raise the humidity a bit. When the leaf tips curl up like that, it’s almost always a sign that the humidity is too low.. ---

Personally I’d bump that humidity up a bit. I don’t run 55% until flower. ---

Hi 👋🏻 I agree with both of you @BluntForceTrauma420 & @Lynx_361. Because I always struggle between 56% and 63%. I know that between 65-70% in the veg stage would actually be best. When I use my room humidifier, I reach a maximum of approx. 61% - 62%. I also hang 1-2 wet towels on a drying rack in the room. Then I manage to reach 65%. Thx ---

So here are my current data: 24.7° / 60% Distance to the lamp 42cm. Center: approx. 380ppfd & the tip: 475ppfd. Today I again moistened with (6.53PH) 300ml in approx. 100ml every 2 hours. Despite 2 LST strings Size: 27cm On the upper left leaf. Here are current pictures. ![1000043664](https://social.growithjane.com/uploads/default/original/3X/1/3/134ba11764dc6e7ed8fe2e7b0dbe0c884608b4f6.jpeg) ![1000043666](https://social.growithjane.com/uploads/default/original/3X/f/e/fef998ee4b4c89f939b190e27a0df264e263491f.jpeg) ![1000043665](https://social.growithjane.com/uploads/default/original/3X/8/b/8b1159cea95aab8eefafd8b4e4fa960c3ddd5470.jpeg) ![1000043663](https://social.growithjane.com/uploads/default/original/3X/b/3/b372f89feb0b23d9d28b79a15c2507856f51f9b6.jpeg) ---

The plant looks good, after all! Now just bump up the humidity a bit, hold off on adding nitrogen for now, and the plant will be happy! 🙂 ---
