Frustrating problem

HIWAY · Jun 8, 2012

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
