droopy?yellow spots.

so i have 3 plants that are 17 days old
I also have 2 plants that are 21 days old

one of the 18 days old ones has yellow spots on its leaves and the other is drooping a bit I think I mioght have over watered it.

one of the smaller ones is just looking bad.

the temperature in there is usualy like 25*C. lighting is a 400w hps.

answers? and when should I start spraying them with carbonated water?

btw this is my 1st grow.

^^^^^^^^^^^^^^^^^^^^^^^^^^

oh and they are in pots 6" across and like 5" tall

whats your pH?(the spots could be pH inbalance)
Have you given them any ferts?(hopefully you havent, it would also cause the spots)
How often do you water?(they look a little overwatered)

ROFL...one of your plants is 18 years old. No wonder it's droopy. OMG

Sorry really medicated right now. LOL

i dont know my ph i gotta get a ph meter
i water them whenever the soil is dry an inch down
I have given them some mild mixed nutes but only once

Oh btw will these pots be big enough for my plants or will i have to transplant again?

Your in trouble without a way of checking the ph

took a hottub test strip and put it in the same water sorce im watering my plants with and it came to about 6.5 - 6.8 then took the same amount of soil as water mixed it in a container shook it and let it stand for 5 mins then cecked that the ph was also about 6.5-6.8 so now i know (hopefully) about my ph. mabey the yellow spots are nute burn, but I only mixed a mild mix. mabey I gave too much of the nute mixture?

I would definately say "slow down on the watering!" They look mature enough to change your water schedule to every 5-10 days. One inch is too shallow to finger moisture test. put your entire finger, 3 inches or so. if dry, time to water. make sure you water plenty, (till you see water drain out the bottom drain holes) and letting it get dry every time prevents root rot, and makes the roots reach down deep for moisture, which is neccesary for the plant to support the buds wieght.
