are you checking your ph, canopy temps.(highs throughout the day), and using de-chlorinated water or r/o water. how often are you feeding them and at what strength
but that plant looks pretty ripe so its not all too bad... it would be 1 thing if they were mid flower, but it looks like that thing might be near the end?
As always though, it would really help in diagnosing problems if you gave a short rundown of the entire setup and what they have been getting fed, etc...
They are only four weeks and I feeding them...advanced nutrients base for flowering plus:nirvana bloom enhancer, big bud, carbo load,B52,bud candy, and hydroplex and great white. Too much? i keep my ph at6.3 to 6.9 and I use Ro water temps in the day stay at 72 -75 humidity under 35 percent .

could up the humidity a little to around 50% (40% close to harvest). just watch the n-p-k ratio you give them sometimes if you give them too much of one thing they wont take it at all,and it will start poisoning the plants . its good to have a ppm meter for when you are mixing different nutrients together to know just how much there taking in/ putting out in the runoff. and use r/o or at least dechlorinated water always.
