Why are my leaves turning yellow on my Sour Crinkl...

In my experience this looks like a Phosphorus Deficiency. At this stage/week of flowering is when they need the most nutes. Week 5-6 is when you should feed the most. I would say for the look and size of those plants, around 750-800ppm Hope it helps, you are going to be fine anyways (:

Thos is normal at this stage. She is just grabbing all the extra nutrients from those fan leaves. She looks fine bud

It's because they want more Nitrogen.

I'd say it's either just a case of being an older leaf and/or flushing. Personally I wouldn't worry. It's week 9 after all. I'm no expert though, as long as newer growth is healthy there shouldn't be any problem.

Seems to me they just miss their old location but once they adjusted to there new surroundings I’m sure they will turn around. 😂 😂 😂 😂

Seems like normal finishing low nitrogen. perhaps a bit early but not really? idk i always mistime my flushes and nutrient regimen changes and end up not getting this. seems fine, you dont really need too many leaves anyways and you want the plant to use all of its stored stuff like nitrogen for smoothest flavor if you think its got more than a couple weeks you can up the fertilizer theres a chance its light burn on theolder leaves because it takes several days to show up
