Doesn't scream N, P or K ... yellowing is from the edges in and no lesions. Could be micro nutrient deficiency. You should be lightly feeding them if they've been in the black gold more than 3-4 weeks.

I love this product:

That and CalMag have been in my toolbox since I started growing indoors.

Been able to head off unexplained issues many times with those.
Including lightening/yellowing of leaf edges.

It looks imo like you need to start lightly feeding as suggested. Get some micro nutes in there. Next feed would be best

@Hazy480rizzo Give them light nute feedings. I would say It could be early magnesium deficiency, if that yellowing would continue to spread inwards. The stems are also a little purple.
You can probably add calmag every, or every other feeding.

You mentioned you fed them already, so just keep watching and they should bounce back in a few days.

@damian0536 Could be genetics maybe. You should start your own thread and provide as much detail as possible.

Looks like a magnesium def to me! Certainly not n.p.k, add a few doses of Epsom salt, dissolve it in hot water and add it to your feeding water! 1/2 teaspoon per litre! :)

Just keep going man, less grow nutes more bloom now and keep upping the bloom and eventually no grow nutes by like 3/4 week of flower! Keep the bloom going until flush, this is basic but good advice! Try to keep humidity between 40-50% and in week 7/8 try to get it down to 30% :)
