leaves on top turning yellow? why? and how do I fix

O ny plant is about 3 weeks in vegetation stage and some the leaves on top are starting to turn yellow on the outside in is this because they're burning? Or some kind of nutrient problem also how do I fix it

they are yellowing because they want to...leave the nature to do its thang ma man peace!

That info ^ is incorrect. A picture would be nice. Did the yellowing start on the top set of leaves? Hard to tell with out a pic, could be nitrogen deficiency, heat stress/burn. Idk

yea i know i was joking

They're yellow because the yellow light is staining the leaves, but only on top.

Without good ventilation, the yellow photons accumulate on the leaves and stain it yellow.

You need more green light to make it look green.

Wow lmao. Give the kid a break. Its probably nutrient burn. But to be safe raise ure light an inch or so and just water with PH'd water to clean out the soil then feed lightly. Is there a crustyness to the bottom where the water drains out. Also pics would clear the smoke more then words.
