1st Soil Grow! CKS NLA in FF HF :)

Hey there living it, you're on point for week one, just keep the humidity and temperature as stable as possible . For an auto you don't need to add any nutrients until week 3 even until flower should be fine. If you do add nutes go 1/4 strength and go slowly so the plant doesnt get burnt. Hope this helps ! 🚀

Hey I saw that you had your light at 16 inches. That caused the burn spots and the curling on the leaves. On my 1000w leds I run about 36" at this stage then go down to 24". Any closer than that will burn them. All leds are different though and usually have a manufacturers recommended height. Looks like you have it at 48 now. It is fine to leave it there and watch for her to start stretching. If she starts stretching then move it down a little each day until you find that sweet spot. As far as your ph. You can take a sample of your runoff water from the bottom of your pot when you water and it will tell you what your soil ph is. Happy frog is a high quality soil and is usually buffers ph really well. Hope this gets you headed in the right direction. Good luck!

I'm not seeing any nute burn in your photos. But I would like to mention some of your upper leaves closest to your light show signs of heat/light stress since the leaf blades are starting to curl upwards. I would consider back off your light a bit and see if they lay back down. If your getting serious about growing you should really consider investing in a PPF/PAR meter which will help you measure the intensity of your light at different distances and part of your grow area. I use one every grow best tool I have no more guessing. As far as flushing goes some auto flower growers will do a flush around week 5 then switch to bloom nutrients just to help remove any excess nitrogen that is not needed as much during bloom. It's a matter of preference. I personally will flush to bring my runoff TDS below 900 ppm (Hanna 0.5 scale) or 1.8 e.c. Then let them dry out. Next time I feed in the 450 to 500 ppm range and measure my run off ppm. If it's high then they get plain water next time. I do this to ensure they are actually feeding off the nutes and they are not accumulating. Hope this helps. 👍
