I'll have pictures in 1 hour, but till then i can only describe it.

There is a yellowing of the lower leaves on my biggest plant (still not that big 3 weeks old), And now my other two smaller ones are slowly developing it. Do you think its lack of nutes? are they old enough for them? i checked soil ph and it was light green which means under 7 above 5 (seriously such a bad gap lol).

What do you guys think

Short version: my plants have white spots on upper leaves, yellowing on lower.

was reading the guide on how to diagnose.

Two came to mind Nitrogen deficiency and Magnesium deficiency

Will my 20-20-20 nutes take care of the Magnesium deficiency? Or do i need something else?

it depends on your nutrients. look on the label to see if it contains trace minerals. all complete fertilizers will contain it.

there is not enough information in your post to diagnose anything. medium + light + seed/clone at minimum. pics would also help.

Medium = miracle grow
Lights= 1 led pannel and 2 cfl's
Strain = Early misty

Pictures will be ready soon hopefully.

yeah that doesn't look great. you didn't spray the leaves with any nutes did you? did you check your fertilizer to see if it has Mg?

fertilizer has mg, i think the leaves got sprayed with a vary vary minor amount of miracle grow all purpose plant food, think that is it?

yeah they're pretty sensitive to that. i accidently sprayed a very mild flowering solution on my clones last week, and a number of the younger leaves looked a little something like that. watch it!

what kind of CFLs have you got?

Your plants will survive without nutes fine. Dont give them nutes until you think the root system is well established. First time you give nutes, give at a quarter strength. Wait a couple waterings without nutes, then try half strength, and repeat until you are at full strength.

My cfls are 60 wat 5500k's only like 600 lumens each, pretty weak but they have really nice reflectors around them. When my plants get bigger i'll add more, this is what my set up looks like

okay so first off i think you mean 60W equivalent if they're only putting off 600 lumens ... think that's actually a 13W bulb. i would probably actually move them a bit closer, say 3" away or so. give em a good flush and you should be money.

Ok i added the nutes for 1 watering at 1/4, then after watered with plain water when it dryed. I'm not certain but it looks like they are making a comeback, at least the plant with less damage seems to be getting green in its yellow spots. The more damaged plant has stopped spreading yellow so far. Hopefully this will continue.
