Two questions about my baby and mommy plants (pics)

[timeflow]

First, I have 13 two week seedlings potted in MG soil. I flushed the soil and dried it prior to germination. Half my plants are growing well, the other half appear stunted, with lime green leaves or yellowing leaves with some browning spots. I haven’t added any nutes and I’m not certain they haven’t been over watered. If I can get them to rebound, I plan to transplant them into pro-mix or ssm#4 soil. Any ideas what may be wrong.




Second, my female plant is one month into flowering and the top 2/3’s of the plant is doing well – the dark areas beneath the buds are shadows, not dead spots. However, the bottom 1/3 of the plant has cupping, yellowing and drying leaves. Nutes are 10-15-10 and a 0-0-1 seaweed fert, all applied sparingly about every 6 days. There is new growth around where the old leaves are dying off. Any ideas what may be wrong here.

Bumping for a Saturday night try.

looks like nuteburn. shoulda started with sterile (nute free) soil. they are not supposed to have nutes till a month old after its established and not considered a seedling anymore

I transplanted all 13 this afternoon using 90% Pro-Mix Bx mixed with 10% dried backyard dirt. I'll see what happens.

Sorry man, but that's not true. They need nutes from the beginning. When in soil, it's a rule of thumb that they won't usually need nutes for about a month, because, the soil has enough nutes to sustain them for that long. If it did have any nutes,(at all) they'd die within the first week or so, after they burned through the nutes that Mother Nature gave them to start with.

They're born with enough nutes to get them through the germination period, until they have grown roots, and their first set of true leaves. After that, they need to get them elsewhere.

Still, MG is shit soil for any grow. MG is water released nutes so everytime you water it's releasing more nutes each and every time.

^Wrong. MG is called "shit soil", because growers mistakenly keep it too wet, for too long. If enough perlite is added, it's not a problem, at all.


But, I'll never use it again, because of the fungus gnats it carries. So,...yeah, it's still shitty soil.

 

[tybudz]

MG is shit and thats your problem. the soil is packed with a bunch of nutes not suited for buds. go with foxfarm or just make your own !!

 

[jawbrodt]

They're starving, not overfed.

 

[timeflow]

You’re both right, MG is shitty soil. It holds too much moisture and nutes the hell out of the plant, especially with nitrogen. Also, after a dozen or so waterings’, it seems to bind together and harden like concrete.


I thought by flushing it first would work but, it made it worse.

 

[jawbrodt]

^I'd start foliar feeding, until you get this straightened out. That'll keep 'em happy, til then.

 

[timeflow]

If they’re starving, I’ll know within a week. It took topsoil from my yard, 70% of which is clay dirk, and sifted, dried and pulverized it to the consistency of powder. It’s so fine you could snort it. And I mixed it with a ratio of 90% Pro-Mix BX.


I’ll add some Neptune’s Harvest fert’ in a couple days.

 

[jawbrodt]

Well, it's really hard to say from the pics, but, it looks to me like they've all started yellowing, somewhat uniformly? If so, that means they're starved of nitrogen, and probably others.


I hope your solution works out for ya.


P.S. I don't wanna sound like a prick,lol but, you're asking for trouble if you took soil from outside, and brought it into your growroom. Unless you sterilyzed it first, it could be carrying pests, particularly....spider mites.

 

[jawbrodt]

EDIT: I just saw the care you took before bringing it in, and think you should be okay. Sorry 'bout that, I'm half-asleep.lol

 

[timeflow]

Well, if I get mites I’ll be ready for them; I had spray my flowering plant Friday night with spinosad to kill thrips.



Everything that can go wrong, I've got going for me.

Last post for tonight, one correction: I meant to say about 30% of the top soil in my yard is clay dirt—or dirk.


Not even spell-check is working for me.
