Day 40 yellowing tips

[Desert King]

Hey friends. My first grow. 3 chemdawg kiwi and 3 juicy fruit. Growing in miracle grow with 3 true 95watt led's. None of them have begun any flowering. My concern is the color on the tips of new growth and on some mature as well. Thought maybe light stress? Just raised the lights to about 2 feet. Do they appear to be ok?

You are right to be concerned but do not be alarmed. While I don't know what is causing that, I think I can safely say it's not the light being too close. It may be some slightly hot nutrient around the roots or it might be some other mild stress, but at this stage it does not look like a problem that needs urgent attention. It may not even be a problem at all. I'm not a soil grower so take this with a grain of salt but I'd give her a bit of a water flush based on some recent experience in an eazyplug pyramid, and continue doing what you are doing. They look pretty good to me.

Thank you so much

Definitely nutrient burn. Not a big deal. Just dial them back a little. They actually look pretty good.

Light stress would impact the canopy and one of the symptom is that the leaf edges are curling. I'm not seeing that in the photos. Some of the leaves that have light blotches in them are well down from the top of the canopy. How have you changed your lighting//have the plants grown into the light?

If you Google "cannabis curled leaf tips", one of the hits you get will be re. lack of nitrogen. In addition to leaf tips curling, the leaf color is light green rather than a medium green. That's the second symptom. You might want to check the level of nitrogen in your nutes.

I wouldn't be alarmed by I wouldn't drop it. There's something off.
