Strange spots.

My girl here is only 11 days old she was doing fine up until this morning when I noticed these strange spots starting to appear. Here is some info: miracle grow potting soil no nutes added yet, I'm doing 24 hour lighting it sits in my window during the sunny part of the day and under a 6500k 100w CFL for the rest of the time, I water once a day maybe twice if its looking dry "I water very lightly".

I'm thinking maybe its some sort of a sun spot from having water drops on the leaves and sitting in the somewhat intense sun??

Or am I dealing with nute problems??

Any help or opinions are appreciated.

too young to have nute problems. Why are there water drops on the leaves? No need for 24hrs light, they like to grow their roots when its dark. try 20/4 or 18/6.
You water when the plant looks dry or when the soil looks dry?
 
I read that soil can run hot and cause plants to yellow/brown etc and I think that would be considered a nute problem or no? Also please link your source for the root growing at night because I have not been able to find anything rock solid scientific that a dark period in veg is necessary or proven to be significantly better than 24/7, but I am always open to new facts.

I water with water I buy at the water purification store when the soil is looking and feeling dry and I also give it some mist from a spray bottle now and then.
 
i think idea that "roots grow in the dark" is cause the lack of light causes them to stop clorophyl production, so they do somthing els that dosent require light, or somthin liek that
 
Guess I will have to ask someone who has done a test 24 vs 18/6 vs 20/4 same strain same conditions for veg and see what worked out best because I am finding a lot of mixed results some people say yes have a small dark period in veg it promotes root growth.. and then some people say no go 24 in veg the plant never stops growing.

I have been using the 24hr light with good results the roots defiantly are not having any problem growing in fact I had to transplant half way through to day 11 because I had roots growing out the bottom of my drainage holes on my small container that I went to from germ.

But if someone has put this to the test and can say "yes the dark period in veg is great it increased yield" or something similar, I am thinking 24 hour seems superior as the plant adapts and just never stops growing.

And although I am interested in hearing what people have to say about 24hr light vs dark period in veg that question does not belong here I am just trying to figure out what these spots are on her leaves.

Anyone?

1) save 6 hours of leccy a day. you sleep every day don't you? 18/6 is the go - 24/7 will make no difference - except to your leccy bill.
2) Too much water. You say 'I water lightly' but you're doing it too much - let it get dryish where the roots are, not on the surface. Your watering is accumulating to cause a problem - that plant is a baby - would you waterboard a baby?

When I water it is a small amount I don't drench or soak it nothing leaks out the bottom I just give it a "drink" and I have twins so I have had 2 baby's at one time and they drank a lot more than 2 times a day :smile:

and as for the leccy bill its one CFL and its energy saving.. Its not like I am running a 400w HPS 24/7

So are these spots from over watering? you didn't specify. If they are for sure I'll cut the water but I thought veg root systems liked a moist environment vs letting it become totally dry? isn't that extreme? I mean it does do some window time with some nice intense California sunlight which does dry it out some.
 
From a guy named desertsquirrel who knows more than i...
"Always include a dark period during clone and veg, the dark reactions taking place are required for proper occurrence of the Krebs/citric acid cycle and significantly aid in root production."

Hi. Ok. Well, you need to try a process - to me the soil looks dark and wet - maybe because you just watered before taking a pic - you say you're keeping it moist but it doesn't want to be kept moist, it wants a wet/dry cycle. Have you ever left it to the point that the pot is completely dry and the leaves start to wilt from lack of water? It won't hurt, and at the same time you can lift the pot to see what a waterless pot weighs. It does sound to me like something that simple, it isn't a deficiency or ph or anything like that....the only other thing I can think is that maybe you splashed a bit of water on those leaves and then your cali sun hit them - giving you a spot of leaf burn - possible as you're watering them so regularly

Edit: I just looked at post 1 again - you've said the same yourself - think you answered your own question matey! Water acts like a magnifying glass to the sun....
