Leaves Curling up

hello growers thanks for your replies, @GrowingGrannie I am getting my hygrometer this week, this absolutely help me out to know if main issue is temp, not sure if stopping top veg but I will try then. @Aldo90 tbh I am afraid to fully light up the lights, I think it's a temp issue and don't want to burn the plant. About the extractor, I will try to get one @eurorack thanks let's see. Thanks growers.

You haven't kept up your diary and you're not letting us know what temp the plant is in... but this is definitely a sign that it's much too hot... The other problem I see is that you started to feed this poor thing in its first week when autoflowers don't want/ don't need any nutes for the first couple of weeks of their life. I would get the temps down into the 60s, pull the lights away from her (if they're less than 18") and give them only plain pH'd water for the next week... then start them on 1/2 strength nutes... and by then, if she's 3 weeks old now, she should be going into pre-flower so you can add bloom nutes and start cutting back on the nitrogen-rich nutes. She's just too hot... cool her off!

It's only the set of 3 finger leaves. I would worry. I'd also turn that light up fully. Have you got an extractor fan ? If not get one asap. Circulation fans to move air are not essential. Extractors are essential.

in case no one mentions it, you could also chill out for a week and see how she goes, keeping doing what you're doing. I've not masses of growing experience but I feel from what I have grown that giving something a bit more time is usually a good thing.
