QUICK help needed please - Think Different & Sweet Fast Bud #2 yellowing fast

[jah_lives]

The leaves, starting from the bottom of all of the plants, are getting really yellow and the leaves on top of those are starting to yellow and get far lighter green. The plants all are fine on top but its moving up real quickly. The only thing i can think of is that I watered it with "Purified Drinking Water: micro filtered" with a little higher concentration (little less than 1tbsp) of the EJ Grow I've been using (don't know the ph of that concentration), instead of the regular Distilled (ph neutral) water I have been feeding it the entire time.

The plants are all flowering and budding and about 34 days old (3 TD and 3 Sweet Fast Bud). Looking real good up until now. Got them under 2 600watt HPS in big pots with Happy Frog Soil and just been using Earth Juice Grow. I will try to put up some pictures within the next few hours if I can get a camera, but if anyone could help me with ideas i really would appreciate it!

Sounds like a serious lack of Nitrogen? Pics would help alot, and whats your PH?

 

[jah_lives]

Have no PH tester since the beginning but using distilled water and organic nutrients in small concentrations has kept the leaves dark green up until now.

I dont know how it would be a lack of nitrogen though because i've been feeding it plenty of EJ Grow which has nitrogen. Maybe phosphate? I'm not an expert though, this is my first personal grow and only second time trying to grow. I'll try to get some pictures up really soon.

distilled water is stripped of everything. I use ro water and add microblast earth juice and cal mag additive for purified water.

It doesn't matter what water source you use you really need to know the ph of the runoff from the plant.

Purified drinking water is just tap water through a charcoal filter so you just chlorinated your plants.

I am not very familar with happy frog or what should be added when using that medium.

Pics would help with the diagnosis.

Sounds similar to the problem I've been having. Are you using a tent? If so what brand?

First off hello & welcome. Are these auto flower or photo? I'm guessing auto, if at day 34 they are budding and flowering. And if they are budding and flowering, the leaves SHOULD be starting to yellow up as nitrogen begins to be 1) withheld & 2) depleted.You say they shouldn't be deficient in nitrogen, as you are feeding them as you described. Not familiar with the Earth Juice.but in my experience,as flowering sets in and as it progresses, nitrogen doses are dropped, which accounts for the yellowing of the leaves.Is it possible that they are just ripening? This is just a shot in the dark...anyone else?? One thing that I am CERTAIN of...get yourself a Ph meter for your watering / feeding mix AND a soil Ph tester probe. :checkph: :soil: :gthumb: Good luck and keep looking for answers Puff, puff, pass

These are 5/6 of the plants right now. Not using a tent right now, just white trash bags for reflection. Not ideal, but don't have a lot to spend.

Looks like some water splash on some and some normal dye off on the others. I don't see anything to panic over. The bottoms would get better air circulation if you had more soil in the pot and you have her pretty deep in there but the bottom leaves are always gonna die off like that.
