1st grow question

Hey All, I am a newbie and would appreciate any feedback. I just started my first grow. Its a DWC hydro setup. 1000 w led light 4 plant system. I have a 5 gallon reservoir and I'm growing in rock wool. I am 3 weeks in my grow. I started from a seed. The strain is white widow. Temp in tent is 79, 35% humidity, reservoir is 68 F. Nutrient level is 1.3 ec currently. I have attached a picture. Everything looks ok to me but would love others opinions.

Looks good. But I would watch that high ec level. A plant that big I would normally run about 1ec.

My current plants are like ten times the size and they are currently around the 1.35ec mark.

Just watch the tips for burning and dial it back if needed.

Just noticed you said they are three weeks old. Maybe a little small for three weeks. Here's my last lot at three weeks from seed. Think I was only running like 0.5-0.7 ec

Also you say rockwool. But that's clay pebbles?

After opening the photo for a better look, Id say dial back the nutes a little

Ok thank you yeah today my tips look like this… you think its too much nuts or a deficency?
Thanks again for the feedback

they have only been in the hydro system for 1 week. they were in a tray under a smaller light before that

Yours look awesome!

Yeah the plants are in rock wool and that is covered in clay pebbles

Are the roots in the res yet?

the roots are not long enough to be submerged in the reservoir no. the nutes are flowing through them though.
