Pale green spots!! Please help!

Hello everybody!


This plant is a White Dragon (Northern Lights x Afghan) (100% Indica) about 26 days from germinating.


Medium: 30% Peat, 30% Worm Castings, 30% Perlite
Indoor
150 W Metal Halide (30 cms away, 12 inches)
Ventilating Fan
11 Litres Pot (3 Gallons)


As you can see in the pictures, there are some kind of pale green spots and stripes. Any Idea what could it be? I have to say they grew with the leaf (The leaf didnt grow and all of a sudden the spot appeared, it had it since it was little) This spots also appeared before the first time i fed her.

Now I am using a organic fertilizer and Advances Nutrients Nirvana.


Thanks everybody and continue smokin!!

I bet its from your ph being off. What ph have you kept your waterings at? Both with and without nutes? What nutes do you use?

Hey man!
The nutes are called Top Veg from Top Crop (organic)

The water of my solution before going in is between 6,6 - 6-8. The ph of the runoff is 6,3 - 6,4.

Thanks for the help

Looks like leaf-miner damage offhand.

My plants do it too and I've never had any ill affect from it myself. I find it usually occurs on a few leaves and doesn't spread. It isn't miners because they leave irregular narrow tunnels that squiggle around. This is pretty much straight sided and appears to follow leaf structure.

It might be the start of Potassium def...

I have had this a few times and looking back on my journals I have narrowed it down to either overwatering while they very young seedlings, too low a ph, or I even wondered if it was some sort of calmg issue. The plants will be just fine. Try to let plants stand one extra day between your waterings. Make sure your ph meter is calibrated perfectly and your nutes/water going in is at 6.5 right on. If this continues in a week try adding a 1/3 of the recommended dose of a calmg supplement between feedings at a ph of 6.5. I think at 6.8 you may be out of the range a touch.
