Can seedlings have cal/mag problems at one week old?

I have two seedlings, both in the same exact soil (black gold seedling soil) I have NOT added any nutes of anykind

They are one week old from sprout, both are white widow big bud x

temps are always 75-80 with 20-30% humidity.

If you look at the one pic, it sure looks like little brown spots

But if you look at the one next to it, the leaves look fine

Is it too early or am I being paranoid?

You watering every 3rd day how old are they about a week they look I use da sunshine mix 4 and tap water with my seeds first week then after 7 days or a week if you must then I feed a low dose of veg nutes like 3ml sensi gro with half as much voo doo juice and B-52 this is 1.5ml of each phed the same as my tap water that they like at 6.7 even if it says PH Perfect it'll have a ppm of about 300 and then double it every feeding which is every other watering your plants look fine the new growth looks good man..:lol:

after looking up black gold seedling mix i see they use a wetting agent in it. also fine grade peat. when i view your pix my first thought was "lack of oxygen" at the root zone and after reading black golds ingredients list i'm sticking with that. if it were my plants i would replant into a more well drained mix. its not too late. if you turn the one pot over and let the seedling fall into the palm of your hand, look at the small root, if it looks brown and mushy you'll know for sure its too moisture retentive.



edit: don't feed anything. you're just asking for trouble at this early stage.

Yeah far too early to be a deficiency. At this point its feeding off the cotyledons and a Lil light. If anything to its a pH issue. Distilled water can be around 8 I hear.

If you are shitting yourself over them then get rid of them or just change the soil as there may be something in it that is causing it, happened to me once I just let it carry on growing and the new growth was a vibrant green but the first set of leaves stayed the same so all should be good.

The reason why I said get rid of them is because you aren't really too far in to your grow so it wouldn't take too much time to catch up to where you are at now.

looks like you maybe got some water on the leaves while watering. give her time to correct herself, any type of feeding could possibly make things worse. you seem pretty hell ben on doing it tho so good luck

I think next watering i'll add a tiny bit of cal/mg (I real tiny bit, to that one) the other looks fine to me
my ph got wack on 3 plants and the lower leaves are yellowish all new growth is perfect. trying to get them to bounce back but they may just fall off and die or they may hang in there. im not gonna worry about it. my soil is balancing now the runnoff shows the plants are using most of the nutes. keep an eye on ph can really put a slow in your growth. ill post pics monday day 30 i think for my plants and a couple are huge and the rest are close in size. no more soil with nutrients again. ill water feed then so i know what they get and ill know the ph of what goes into them and what comes out.
