Well, not that i am an expert, but i have seen this a few times.
Most likely they are getting too much light/intensity.
Try take a look on some of the hidden (covered ) stems and see if they are still green. If so, you have to raise your lights.
Another reason could simply be the genetics or early signs of a phosphorous deficiency.
PH can also play a part, as nute lock-outs can cause this reaction too.
A few other things can cause it too, so in order to help more appropiate, we need more info on stuff like, PH / Ec or PPM, temps at night and such.
Are they stunted in growth too or do they keep growing.?
Do you measure run-off.?

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Dark Green Leaves and Purple StemsPlant B has had no nutes its entire life in FFHF soil (3 weeks). Stems are a purplish color and starting to droop a little. Water is always pH'd around 6.3 but I haven't tested the runoff yet. Phosphorus deficiency? Heat Stress? Watering conflict? NL Photo just started flowering.

The stems began to turn redGuys, I need your help!
The stems began to turn red. Yesterday it was less, but today it is more saturated and spreads to the veins of the leaves.
Could it be a phosphorus deficiency, or am I worrying for nothing? And what is better to do in this case?

I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white
