Hi guys so my plants are nearly 3 weeks old from seed and are still under one hps 600w light for the moment looking at the one plant it's getting these little yellow spots and bumps on the top leaves and its more noticeable under the hps light of you take the light way you can't really notice it's like some of the leaf has been bleached on another plant it's getting the odd brown rusty spot on a couple of leaves can any one figure this out

I had that i forgot to PH the water so i flush it feed it 1/4 get it back on track they look a little droopy do you need to water ?
 
Well I'm not really checking on the ph properly I checked it the other day and was around 6.5 I use tap water :/ and no I've recently watered them in the last day I was thinking it was a nutrition deficiency ??
 
I have to admit that I have this problem and I gave em some magical and sprayed some thrive on em and they have been 24hrs and seem to be coming back well. you say your under hps is you spay them make sure its at dark

Well I do spray them some times during the lights on I really can't figure out why it's doing this it seems to be getting worse 2 out of the 3 plants are like it now I'm not sure if it's lack of nutrients as I'm starting to get slight nute burn from adding stuff and surely it can't be the ph with soil and tap water what about light burn from the hps being to close ??
 
You can burn your plants when you spray them with the lights on, if the RH is high enough the water can act like a magnifying glass on the leaf and burn the leaf under where the moisture is. I did something like that once, I was told to spray them right before the lights went out but I had plans and needed to be somewhere else when the lights were going to be turned off, so I sprayed them and sprayed heavily then left. When I looking in on them the next morning they looked like this.

It did not burn everything, but where the moisture was just right, it created a magnifying effect and burn the crap out of the leaves.

I would suggest you spray right before lights out or just spray very lightly if you don't

Hi mate I'm not saying it definitely is light burn but it could be it seems to be a little worse than the pictures above from the other day :/ I've moved the light up slightly higher and stopped spraying some one said to me yellow spots and bumps could also be from over watering ?? I can post new pictures if you want ??
