Hope someone can help
I am in the 3rd week of grow and my girls are in trouble leaves are yellowing, and are not very green looking

I am using dwc
I am using advanced nutrient sensi bloom a+b at 1100ppm
ph is at 5.8 to 6.0
air temp in cab is 80
res temp is 70
using ro water
added calmag
roots seem ok no slime but a small bit of brown discoloration about the same color as nutrient
I add hydrogen peroxide 2 times a week
600 watt hps light about 22" above plants

I am going to try to upload pictures but i only have phone camera so pictures are a little fuzzy

Your stats look fine EXCEPT for those PPMs', are you sure your meter is correct? What is your feeding schedule and ratio?

Those pictures suck, all I can see are the burnt up leaves which is probably from the level of nutes your feeding, I say back off of the nutes until she starts to look better.

arent the roots suppose to be white? dunno I have never grown hydroponically before but could it be root rot?

lower your ppm to around 750. and adjust ph to 5.6-5.8, young girls need a lite lower ph to pickup the nutes it needs to grow. 5.8-6.1 is good for week 5 and up.

I use sensi grow A+B and there bloom series. in veg i dont go over 600 ppm because it wont turn out good. then in flowering i hit 1100 ppm. and then your ph i run from 5.5 to 6.1 but as soon as i see it touch 6.1 i lower it to 5.5 and so on and so forth. I do this so i get all the nuts :) and dont miss anything. i will some times even higher it myself so i get all my nuts. :) Then u would suggest adding aqua shield to your res, makes my roots all pearly white and boosted my grow :)

Thank you all for responding ,I think this forum is the best thing that ever happened to the internet
that being said I guess i am making a mistake with the over nute I will adjust the ph and dilute the solution to endup with 700 ppm and see how that goes:hump:
thanks again for the help
