Yellowing leaves

[kjc0314]

Hey,
My plant is about 7-8 weeks into vegetative...At first, the bottom vegetative leaves began to turn yellow and eventually crisped and fell off, which I was told was natural. As the plant get taller the vegetative leaves towards the bottom are becoming more and more yellow. Is this anything to worry about or are they going to continuously keep getting yellow and falling off as they grow?
Thanks

I'm using Sensi Grow part A and B right now...Should I just use water without nutes on next watering?

yes, next watering use only water, preferably purified water.

i'm actually about to start flowering in about a week so should I just keep using plain water before then?

yes you always want to flush your plants before you start the next phase of the plants life. when you water your plants for the first time in flowering use half the strength of the nutrients so it doesnt go into nute shock. post some more pics

Yea looks like you need to flush jus with plain water and keep an eye on it for the next week or so

Yea looks like you need to flush jus with plain water and keep an eye on it for the next week or so .....you are switching to flowering nutes righ?

Its quite normal for the older bottom leaves to get yellow, crispy and die off. Once you go to flowering...stand by!! Alot of them will turn yellow.

ok thanks for hte help guys...i can post more pics, but what do you want me to take them of? That's pretty much the worse it looks on any plants

ya, i'm switching to sensi bloom part a and b for sure...when you say to only add half the nutes when I first start flowering do you mean about 1/2 tspn/gal?

 

[kryptakrOnic]

Well I would initially start with an 1/4th strength then work my way up and yea 1/4th teaspoon per gallon water
