Plants lookin bad, any help appreciated

[cowboyup1248]

Hey guys, 1st time grower here in desperate need of some guidance.
these are 2 plants I'm dealing with and here is as in depth of a description as I can give, if more info is needed please let me know what you need and I will try my best to get it.
my plant food has a NPK of 4-16-8 strong start formula. water PH is 8 which i use vinegar to bring down to 6.5, soil ph is about 6.5-7.0 (hard to tell exactly with a probe). here is the problem:
Plant A, seems to have growth stunted, whole plant has turned lime green with redish stems but the stalk is light green, bottom leaves a curling down, and top leaves appear to be cupping.
Plant B, is green with yellow spots and some burnt looking spots on the older leaves between the veins, ph and plant food is the same for both plants. oh and each are in 6" pots under cfl's, temp between 69-74 have no idea what the humidity is. lighting is 20/4.
I've also tried playing some classic smokers music for them, but so far no response.

So, any ideas what could be wrong?

anyone at all?

those seem like bloom nute ratios. r u flowering? pics?

That ratio is an extremely high. The pots are going to need to be bigger eventually. How high is the concentration your using in your solution? How big are they? How long have they been growing? How many watts of cfl's are you using? how far away from the lights are they?

 

[cowboyup1248]

It's supposed to be a root stimulating fert. The consentration is 1/2 ounce per gallon of water. they are both about 4 inches, and about 1 month old. cfls are 3x100 watts, lights are about 1 1/2 inches from plants. 3 cfl's because there is a 3rd plant in there but she seems to be ok.

nah, not flowering, was hoping to have them atleast into full leaf development to sex them by now. its supposed to stimulate strong root growth, atleast thats what the bottle says, but I thought the same thing when I saw the ratio.

finally got some pics, let me know if it helps, I think Plant A is gonna die soon if I cant find out what this is, but it will still be good to know for future reference.

Smokey is right on. Your plants are in the veg stage of growth and that requires an npk similar to this 3-1-2. However since they are so young the soil you are using should be substancial enough to take them through vegging. Flush them good now and they should get better and growth will pick up. If they don't perk up within a few days after the flush they may need a small dose of veg food to get them going.
The npk blend you are currently using may also cause some plant issues during your flowering phase as well because of the amount of P.
Good Luck

Thanks brasmith, I'll give it a shot, and post back if they dont get better.

p.s.- as a side note, the food I'm using is Peters Professional, said it "promotes a vigorous start" but I wont be using it anymore, and also you mention high P being bad for flowering, I thought high P was the way to go for flowering as long as you didnt over do it, and didnt shorten too much on the N and K. is that wrong?

P is one of the most important parts to a good flower food. It is only bad in super high doses. P is good. Have fun and let us know if your issue doesn't turn around.

well brasmith, i flushed plant A, and its still alive and what leaves survived are turning green again, but no growth. Plant B, fed it some mg, and its done a total 180 turn around. shot up about 4 inches since your advise. I dont know if Plant A will survive or not, but atleast I have a good plant still goin. thank you again brasmith, and everyone else who helped in this matter. +rep for you.

Thanks Cowboy. I like to see things turn around for fellow growers. Good work. Plant A may be a bit slow to make a complete turn but keep going forward with it and you may see a sudden growth spurt. Have fun
