Plants Dry?

Hey,
A couple of my plants have white spots and have leafs that are kind of drying out looking. Do i need to water more?

i think so, mine also are drying up the temps are fine maybe circulation and extraction, do u ahve these?

How about a picture?

are you using cfls? if it's white spots, it's usually a burn from the plant touchin the bulb

How old ?
What's ur water schedule?
Lights?

Im using a 400 watt hps, it was at one foot but 3 days ago i put it at a foot and a half. Im watering about 10 ounces every 3 days. plants are very young, about 9 days old.

my camera isnt good enough to give a clear picture, sorry.

clear or not,,,,any kind of pic would help.

the only problem i can tell is the hps being too close to the seedling. a ft and a half is usually where the light is from flowering plants. move it up a little more....i would suggest u get some cfl's or floro's for ur veg. They also sell Metal Halide conversion bulbs for the hps.

really, you dont think the sodium could do it. One of those plants i described just had a wonderful two days though. The other one not so much, its growing much slower and is smaller. ill get a pick.

heres a couple, the bigger one you can see has a spot on the very tip of a leaf, the other one has more.
