Several possibilities.

Your flower nutes could be too strong/weak which would either lock out of simply not be supplying balanced nutes. Most people use too much PK in flower also too little N. Your flowering light might not be adequate in the green range meaning not enough chlorophyll A/B production. Could also be a combination of all the above. hth

No disrespect, but based on your answer I think you need to buy some books.

IE 1000w what - MH, HPS, whose bulb, what ballast....?

What medium... if using pots, how big are the pots?

If you knew how important these questions were, you would have posted this info with your question.

hps bulbs. Sun system cropmaster ballast.
Sunshine super hydro soil. 1.5 gallon air pots.

I just want to hear some opionions to be honest. A lot of people are clueless and it seems like there is a lot of experienced people here.

I agree with the other guy. Probably N deficient due to either lockout or just using flower nutes with no balance of N.
My plants are a couple weeks ahead and the same. Only some of them have alot of yellow leaves, some are perfectly healthy, but dont worry too much. If you have not been overboard on nutes, I say add some with higher N to the regiment
