Anyone care to help diagnose?

So this is 1 of my girls. She is gorilla glue #4 in her 3rd week of veg. Indoor under a gavita flex 750( I brought her outside to get,more natural light to help diagnose her). She is ffof soil and is getting 4th nutes. Ph is about 6.2/6.5 and temps range from 62-80 between lights off and on. She doesn't look too bad but definitely could look better. I've looked at other forums but I'm horrible at finding out what's wrong. Thanks in advance to anyone who can help

I'm seeing a touch of nute burn starting there. By 4th nutes do you mean 1/4 strength nutes? Shouldn't need any added nutes yet with FFOF as it's pretty hot on it's own and I've seen it burn a lot of plants by itself. You can tell your girl is growing fast by the lighter green centers in the grow tips.

If the leaf edges keep curling up more and going brown you may have to flush her a bit but if she gets plenty of light and fresh air so she can use those strong nutes to grow faster it may not get any worse but I think it's close to the edge.

I was growing one like that outside all summer a year ago and she looked like that too. Moved her inside in the fall to finish her off and she looked massive in the grow room.

If that plant is just 3 weeks from sprout you've done a great job so far.

over fert absolutely. no ferts for ffof, at least until you are certain you need to give ferts.

Definitely nute burn. The light green new growth is completely natural, when the leafs fan out they'll darken up.

Awesome thanks for the help guys! I wasn't sure if it was toxicity or a deficiency. I know ocean Forrest has plenty of nutes in it but wasn't sure if it possibly had some lockout going on. I'll water with only water a couple times and see how they turn out.
