help whole plant turned almost yellow overnight.

My widows have been on 12/12 for 4 weeks.they have been healthy no problems..kept their nice green colour. yesterday I open the hut to water them and my one widow has dropped 3shades in colour the whole friggin thing.Ive been feeding flora micro,bloom,grow at half strength. I I have not fed them much.I had a situation here at my house and well....I missed a week of feeding. Also I just don't like this food, it seemed to me that after each time I gave them nutes even at half strength they did not like it..They looked a bit different "unhappy" each feeding. What do I give the plant to get back its colour.The other widow has had the exact same treatment and looks fine no colour change.H E LP>

Without a photo, it is almost impossible to advise accurately.

And what is your medium?.

Nitrogen deficiency. If your using soil, flush with 2 gallons of water and then switch the brand of nutes your using and give it to her full-strength. Most bloom formulas have very little N, so if your using half-strength, then she is getting barely any. sunbiz is right, without more background info or photos it is almost impossible to diagnose your problem; it could be way more complex...but it sounds like a N deficiency. I use FoxFarm nutes and my buddy uses General Hydroponics . We both have amazing results.

Usually when plants go yellow from the bottom up it usually means that you have to increase the watering.

N def is one possibility, symptoms she described could also be over watering.

And I think the photo upload here is broken, cuz' I can't see a lot of posted pics here at the moment...only the paperclip.

even in flower, your ladies need N... just not as much
and ALWAYS adjust your PH before administering...

if you add nutrients and dont adjust your Ph...the solution will be too acidic and your ladies will respond negatively....

6.3-6.8 is the acceptable range...
when I add nutes, it shoots my Ph down to about 5.... way too low....
so, Nitrogen...and Ph UP to adjust your feeding solution...and you'll be fine.

If your growing medium does not have good drainage it is very possible to overwater. But if you grow like me you can dump a couple of gallons of spent res water from the budders everyday and all they'll do is get bigger and greener. When I cut them back to a gallon every three days that's when I start seeing the yellow in the lower leaves of my mom. The spent res water was originally mixed at 1/6 per gallon as recommended for dirt. This spent res water has done fifteen, 15 minute cycles in a flood and drain table. I have never seen yellow in my table except for late in the grow. I run all of my clones from root for ten weeks regardless and all seed plants go 12 weeks from seed with no veg cycle. So unless you tell us what's going on we can only

Thanx I think this is exactly the prob.I am def switching food brands.I tried to upload but ya there is something wrong with the pictures right now.i cant post or see any.Thanks for your time.

Thank you for your time,and yes im going to be switching brands and adding ph up.thank you

Thanks for your time I have lot of great info from everyone .

thanxs for your time and response.

I think there is aproblem with posting and seeing pics today.Iv'e tried but no go.im hoping to post some today.Im also trying to post a pic of 2 others im not sure if they r ready to come down...close real close.They were two freebies I received with my order of the widows.thanks for your time.

the switching brands part may not help....(or hurt..for that matter)

almost any 'brand' tailored for ganja will do great if you use it in moderation and adjust Ph before administering....
see... the science of it is actually quite revealing...
there is a certain range of Ph where the roots absorb nutrients...
too high or too low and it locks out any food that is in your solution....
even to a point where your plant will seemingly not want to even take water for weeks on end.
once you get your Ph right, you'll be fine!
