600w hps is not enough for a four foot plant. temps are too high for daytime. did you allow time before adding nutes to your mix? if so you may be low on N. at two weeks your flowers are looking good. im going with N deficiency. in flower plants still need N so keep feeding it.

pH of 6.3 at runoff is fine.
This plant turns yellow and dies naturally after growing for "x" many weeks; it's an annual plant, not perenial.
Give nothing but water to rinse out the ferts and let it die. Your bud formation is a clue the plant is just about done.

she looks fine just keep doing what ya doing.. i wouldn't add more N if i was you plenty left in the plant for what she needs.. flush the last 7 days for a cleaner nicer smoke.. looking good GB nice job..

[MEDEDCANNABIS]

yellowing to me says i want more N. not a lot but, some. if your organic i wouldnt worry so much about flushing. one or two is usually sufficient. im still saying they are too big for a 600w. you look good for the deficiency though. not to mention plants that size require more nutes, hence your deficiency. the fact they look that good says that eve:thumbsup:rything else is where it should be. good job:D

what's the outcome of this grow?

[GuerillaBot]

looking pretty good. tops are still yellow but it has some white mixed in also. looks like a mag def but I have heard if its white its iron? these arent the four footers either. theses are about 28inches under a 1000hps. also running a 600watt next to it. its not the lighting im sure. this is the same thing happening for 3 grows. keep getting early yellowing that turns white in between veins. leaves are slightly dry feeling and cupping any ideas?i think it could be from overwatering that caused a slight burn. new growth seems fine with mild yellowing on a few of the small leaves around bud sites. i keep experiencing this same thing around week 3 of flower. im gravy til then. peep the new pics and hit me up
