N Def? Looking for 2nd opinions

explosive82 said:

Been growing for about a year or so and have run into this problem (see pic below) at first i thought it was a nitrogen def but i'm starting to see weird stuff and would like a second opinion, i've looked at deficiency charts and what not but if you can't tell by the pictures i'm just seeing alot of yellow (on week 4 of flower) so any advice anybody could give would be great

ph is always measured to 6.5 and rh between 38-50% with temps no higher than 81 and no lower than 70

If i left out anything please ask if it will help i will try to provide the info, most of the affected area is the bottom-mid area (plants are about 3 months old) the only thing that has affected the very top leaves of the plants is that very few leaves are getting a few light yellow spots (hence why i thought it was N def)

It does happen, but premature yellowing is a sign something is wrong. Yellowing is OK later in flowering though

my rule of thumb to be normal is yellowing 3 weeks into flower way i run mine been fine for years

Those look good, props man. Some people prefer less nitrogen during flowering so leaves fade yellow earlier, that's common

Do you use ro water or tap? And did you use any bloom boosters? What nutes are you running and at what dose?

i use water from the tap that i let sit for 2 days before using. The nutrients i use are http://www.amazon.com/Botanicare-Blend-Plants-1-4-5-1-Quart/dp/B0002E5O7S , Cal/mag , and Beasty Bloom

it didn't really happen all of a sudden, sort of just slowly happen over the last couple weeks

Does anybody know if Monterey insect spray helps with PW at all? i'm guessing it doesn't but thought i'd ask if it doesn't how safe would you say it is to spray with sm-90 after an application of it?
