pH has nothing to do with your leaves's color. Green is good, foliage produces bud. Something else is at work here regarding your poor production.
Ah......prevailing attitudes and the never ending forum paradigms. If you can find any reason, botanically or chemically to "flush" before harvest, I'm all ears.
Good luck,

this thread is very informative for the novice grower. I'm having trouble w/ 6 /10 plants the botton 2 leaves are wilting and curling, the rest of the way up is a o k. drip water 3x daily 15 min. don't have ppm . ph always 5.5-6.5. Is this from overwatereing and/or too much nute?

Ask Mexican or Colombian growers if they "flush".
A plant is not a car radiator that can be opened up or closed down.
Hi UB,
I am in the 12th week of my first grow, still veging. I am growing in a cabinet 3'x4' by 3 1/2' tall. I have 8 27 watt CFL's at 5500k, and 4 26watt CFL's at 2700k, 2"-6" above the plants. I also have 6 20wat tube flouro on the surrounding walls. I use a 20/4 light cycle for veg now. The interrior of the cabinet is painted white, it also has a 4" exhaust duct.
I started with MG soil, but switched to Kellog (I hate this stuff) when I repotted 6weeks ago, no damage to root balls. I have both over and under watered (mostly due to the Kellog soil), now I pick up each 10" pot every day if it is light I water, if heavy no water.
I also had what I think was a nute def. that showed a week after the transplanting. Yellow tips and edges to the leaves. I held off adding nutes believing the "Their weeds. They will grow with just light dirt and water." theory. I waited and watched for a week thinking it might have been stress from the transplanting. Things did not get better. I did not use the MG soil for the bigger pots because of what I read on this site, I should have kept the MG soil. I have started using Shultz's plant food 10-15-10 at half recomended does once per week, three weeks ago. The new growth is looking better now and the most damaged leaves are begining to turn yellow and drop, but the new ones are green. I have one plant that the leaves are green but they have a warped or twisted/wrinkly shape.
Note: I have not "flushed" my pots to date.
Am I facing another problem or do you think patience is needed?

Huh?
I think you need to take a course in Botany 101. Grow some tomatoes, indoor plants, etc.
Good luck,

It appears my ignorance and lack of education have annoyed you. I am sorry to have sounded so clueless that I am not worth more than a snappish response.
Too bad really up until this it seemed like you might help me, you seemed nice and approachable, Guess not.
I will continue to grow and see if I can find some success with out your advice.
I don't need luck, I work hard!kiss-ass

In a sense, yes. I'm not here to teach basic plant culture. That is something you learn on your own by growing other plant material before you try your hand at pot. BTW, this thread is about plant moisture stress. Having said that, my comments.......
For starts, CFL's suck, so do cabinets.
You don't give a plant a high P food if you're trying to encourage foliage production....reason for the lower leaf drop. You have a N deficiency.
Anyone that is still vegging after 12 weeks should consider another plan. How big are those plants anyway? If they're not 18" tall or better, something BASICALLY is wrong and it's not an issue of "patience". After 3 - 4 weeks from the seed popping, I'm ready to flower, and, the plants finish around 42" or more.
Good luck,
UB

Is it a good idea to actually completely saturate vegging plants in water once every other day? My room temp stays around 80-85f. Will this level of soil saturation draw insects or mold over time, or should i just make sure that the temperature, is at a level that will promote a good level of evaporation. I also fluff/turn/till the soil regularly, so that the wettest part of the soil goes to the top. Is this a good technique or will it produce problems for me in the end?

Hey Uncle Ben,
Can you helpe w/ this? Switched to flower 10 days ago, noticed this about 5 days ago. I read your post, but I can't come to a conclusion. The only things I can think of is that the temps did go up to 83 degress one day, or that my night humidity is about 70%, but I'm working on that (it has always been that high, never had a problem before though).
Strain: DP blueberry
Light: 2 1000watt hps
Temps: usually about 76-78
System: ebb & flow, pots w/ hydroton & rockwool
Feed: Lucas formula, 3x/day, 1/4 strength Koolbloom
Thanks a bunch!

What's the NPK of KoolBloom?

That's what I thought. You can't grow decent plants without the most important macro, N.

hey UB, i hope you can help cause i sure am stumped on this one, i am growing a bubblegum strain that came from a 10 year old mom 2 years ago, the guy that i WAS growing with, never mothered off that plant and just the cloned from the veg box every crop, buds have always been huge and solid, now, i have had this problem with my last 3 crops of more leaf then bud, on this crop right now, 3 weeks in, they did have lots of white hair, until yesterday (3weeks) when now they are starting to produce leaf out of the bud, i am stumped on this, i asked a long time grower from my area about it, and he's stumped, could this be degeneration?
p.s. happy 4-20

I'm not sure what the issue is. The amount of bud is directly proportionate to the amount of leaves.
Happy 420!
