yellowing and brown tips getting out of hand pics help!

Hey my plant is in the veg stage right now, its been vegging for 3 weeks now and the lower leaves are yellowing pretty bad, and as the new growth comes in the older leaves start yellowing pretty bad. I do use fertilizer every other time i water it, im using all purpose tomato miracle grow(18-18-21), but im using very tiny amounts in the water i use to water my plant, the temps in the room are at about 75F when lights are off, and about 85-90 when the lights are on(im using a 45watt CFL and another 42watt CFL), im not sure the ph of the water, but i just use tap water in a bottle and leave it on my window sill, and let it sit in the sun, i herd this gives the water nutrients by a friend of mine. but yeah take a look at the pictures, if you know what the problem is id really like to know i dont want my plant to die. thank you

doesn't look like a problem unless it persists then I MIGHT suspect a PH problem. What's your idea of light nutrients in teaspoons per gallon of water terms.

hows your ph if t
hats of could have nute lock up plant cud be tryn to use all its goods from the lower leavses

2.50mLs per 455mLs of water is that too much?

is that liquid ? then I don't know what is proper I use dry powders.

yeah the miracle grow is like powder that you put in your water, i dont know my ph, how do i figure out what my ph is?

uh it's expensive and probably not your problem.
So I'm converting 2.5 ml as 1/2 a teaspoon right ? If so that's 4 teaspoons per gallon. That would be full strength, too strong and the damage is probably nutrient burn.

so should i just water with normal water for the next little while? and do you think i should get some new fertilizer, or will miracle grow work when the plant is a little bigger, i will use a smaller amount of miracle grow as well.

that's all you need to do, try 1 teaspoon per gallon every week, and water first ('till it runs out the bottom) to wash out the leftover salts from the previous feeding.

k thanks man

i think you need a ph meter and you need to flush you plants with distilled water at least a gallon each ,keep a close eye on ph
