Yellowing Leaves - 3wks in

Dr. Who said:

Danksta's pics tell me amendeld K use and colder night temps. ( K ain't bad )
I suspect some added Mg (at amounts higher then 5ml per feed) and S ....
He push's his P a bit to much,,,,but not as bad as most try to.b
He also runs longer then the seed breeders report says (8 weeks = 9-10 weeks).

Can you tell me why I said that?

anybody?

Because the plants in those pictures are fried from obvious excess P?

Pic 1 is worse then 2 on that.....1 shows way to much P use. Correct on one question!

Care to take a stab at the others?

My idea of asking this way is to give a learning opp. to put a picture to an answer for further knowledge down the road.

The way the plant is turning purple tells me that he has supplemented the K, also that night temps are swinging by around 15F. The yellowing , the P. Chances are that the P&K supplement are a high one. Not totally a problem but, I would not have added so much P. The plants potential would have been better served by less. The high K is not so much and issue. Amended K for expressing color in the plant can be done and not hurt the plant. The K use here is not bad.
The trich structure hints that a Mg and S supplement may have been used. The use of something like a "Sweet" will increase trich production.
The overall look of the bud structure (swollen calyx's and the totally brown pistils) say this is running to a proper finish time (longer then breeders report).

They look good! Personally, I would have used a bit less P but, that's all really.

Well done.
