Is this natural

[chicks]

This being my first grow I am not sure if this is natural or nor. The water I am using is ph between 6.5 and 6.7. I am giving them bat guan for P the only N they are getting comes from the Cal/Mag then I am giving them Molasses for K. I am attaching a photo so you can see the yellowing of the big leaves. I am giving these Nutes every watering. Any Advise will be appreciated. Thanks in advance. Oh yes also should I remove the yellow leaves or leave them be?

Normal leaves turn yellow near harvest. Once they are completely yellow they can be removed

How many weeks they been in flower

[chicks]

They should be ready for harvest around Sept 15th or so but of course it could be a little longer it all depends on Mother Nature. I live in Oregon and it has been Smokey and now is cloudy so they are hardly getting sun right now.

Plants are good you will be triming them up in no time.

Oregon here too. Dont you love smoke? Just kidding, of course. Agree with Jibbler here. Yellowing near the end is normal and is signaling end of the road. They look very nice. Enjoy!!!!

the bottom leafs look like they are yellowing first so it could be age like jibberjoe said . How much N does the calmag have , they are in bloom so it really doesn't matter but if thats what you use for the whole grow then a n deficiency might be the problem, taking all the big fan leafs off won't hurt either

When they were in veg stage and pre-flower I used bat guano high in N but when they went into flower all the are getting as far as N goes is the 2 in the Cal/Mag.

They have been in flowering for almost 4 weeks now. The Cal/Mag has 2 of N and nothing else. As I stated above I am giving them Bat guano that is only P and Molasses for K.
