One Week Old and Yelowing!

Hey guys, I have 4, one week old Blue-Cheese females from seed that are showing interveinal chlorosis on some of the larger leaves. I have pics below, sorry they are from a camera phone.

They are potted in pro-mix with some added perlite and I fed them a very weak dose of Botanicare Pure Blend Pro Grow ("seedling dose" on the bottle) last week and a slightly stronger mix yesterday (mid-vegetative dose).

Is this from too many nutes or not enough? Should I flush the soil out? OR am I being paranoid? Thanks, this is my first time with a blue-strain and I want it to go well!

[Oh and please pardon my spelling, I'm having a bad day medically]

Probably over watered,is there lime in the mix,if not add some.

No, no lime. I only added that to the soil mix I will be transplanting them into later... you think the ph is really that off in only a week? They are wilted in the picture, but thats because I had JUST watered them, they are perky now.

Garden lime,also gots magnesium.Only water when the pot feels lite.Have a look:http://www.weedbay.net/overgrow-thebook/PlantTrouble/Merged.htm

I jus up rooted mine today from yellowing/burnt tips. Going to start fresh. I'm guessing moisture or over watering. Hope I helped. Good luck.

Thanks guys, looks like it fits a magnesium deficiency... but I HAVE been over watering so I will let the soil dry a bit and water in some garden lime later. Would cal-mag also work? I have a bottle of that from when I tried growing in coco. By garden lime, do you mean dolomite-lime or hydrated-lime? I have both but the dolomite lime is in pellets and I know hydrated lime you have to be careful of.. Thanks for the help guys!

Like 1kooguy said, when it feels lite add a little water. Kind of get the feel of the pot when you think it's dry so it well be easier to tell the difference/if it needs water or not.

No need but will help somewhat with the under/over watering.

Hey guys, thanks for the advice so far but the leaves are continuing to get worse and it is definitely a magnesium deficiency, Textbook, literally. Also, the soil is just not drying out, even with two fans blowing on it. You guys were right, it's like a peat bog in those pots! I didn't mix the soil right (I rushed that part).

So I'm wondering, I have a soil mix I made up for them when they were older laying around: Half Ocean Forrest, half Pro-Mix, dolomite lime and a lots of added perlite and sand. Real well draining, airy soil. Would transplanting them now to larger pots with more well drained soil help? Or should I just add cal-mag and wait for them to dry? I don't want to loose this batch, I need a harvest badly but they are getting worse fast and vertical growth has stopped completey.

Thanks for the help!
