Is this light stress?

[franco7598]

This is my first grow so I’m not sure if this is normal or if there is a light issue.... or maybe something else? It’s an auto seed in the 4th week of flower growing in coco with temps from 65-75 and RH around 55%. Led 600 watt light about 3 feet above canopy. I turned the lights down a little and it seems to have helped a little with the yellow tips on the leaves. Any insight would be greatly appreciated..... thanks guys

The very tips almost always go brown so that's not a worry. I do see a bit of light stress but very minor so you got it early.

Looking pretty good otherwise.

If growing in pots you should water the pots well then don't water for some time. A 2" sprout will have a 6" or longer tap root so it means nothing if the top couple inches of soil is dry if the pot still feels heavy don't water for a while. They need light on them the second they break the surface or they will stretch up real bad trying to get light.

You really should be asking your question in a thread you start and not in someone else's but I didn't notice you weren't the OP until now.
