Did I over or under feed

So many conflicting information both from fellow growers and website blogs and grow sites, that I'm not sure what to do here.

Strain: crop king Early Miss autoflower

How old: technically 2 weeks since germination, 8 days since it sprouted.

Substraite: coco coir 70/30 perlite

Pot: 5 gal

Light: 600w led at 24inches with two side 23w/6500k CFL 18/6 hrs

Night temps: 65-70
Day temps: 77-82

Prewashed coco in ph 6.0 water with cal mag

First watering plain ph 6.0 water

Week 2- ph 6.0 water with cal mag, with half required amount of veg and bloom nutes.

2 days later, leaves look to be showing signs of stress.

This is my second auto grow. The first one I made lots of mistakes and she was stunted very early on. This time around the seedling has looked great till now.

would need more info about this. do you have an EC or ppm value that you fed? if not, how much calmag and nutes per gal of water did you put?

1/2 what it says on the bottle would actually be a fairly strong dose. especially for a seedling.

It says 1/4 tsp on the bottles per gallon so I did half of that per gallon of water and am feeding a cup of water at a time. Cal mag I did 2ml per gallon.

no problem. seedlings need very little nutrients. there is enough in the seed/cotyledons.

i dont grow in coco but i do grow in peat which is also inert and i usually don't feed them until about day 10.

Never run plain water through coco unless you're rinsing it prior to running a mild nutrient solution through it to prepare it for use.

You don't need to water seedlings everyday. You can let the coco dry out until slightly damp when starting seedlings. It promotes root growth. Seedlings that size 1/4 strength nutes and increasing the strength as the plant gets bigger.

I never fertilized my seedlings ever. I wait till they are about 2-3 weeks old.

They're growing in coco. 2-3 weeks would be a long time to grow in an inert medium. In decent soil nothing would be needed for 2-3 weeks.

Thanks for the information and help. I'm going to get an EC meter and make sure I'm doing the proper amounts. Also not watering everyday. Just every 2-3 days

I missed the coco part. My bad. Yeah I’m in soil. Should have paid closer attention to that.

As I read this thread, I knew someone would post that. So no worries, if it wasn't you. it would have been someone else. lol

It was a little nerve wracking first time I fed a tiny seedling in coco...but they get behind the curve so fast. So I start feeding early...

No biggie. You gave proper advice for those germinating in soil. Maybe someone will use that advice and not nuke their seedlings thinking it will make them grow bigger faster.

That's why I start my seeds in small nursery pots "2.5" x 2.5" x 3.5" of a soil seedling mix I mix up myself. When they get big enough I transplant them into 100% coco. The small amount of soil doesn't effect anything and I treat as coco after transplant. And I can go for a couple weeks of water only before they fill up with roots and are ready to transplant.

Interesting idea XT...and who doesn't have a bag of soil laying around? Standard grower accessory...

As noted...never water with plain water in coco. Never.

Feed your plant...it's all she gets...without your feed, she's screwed, so be nice and feed her...from day 1 when you're in coco.

A 5 Gal pot is way too big for this thing...Solo cup then 1 Gal then 3 then whatever, if you feel the need. But I'll say this a hundred times. You can grow 6' plants in less than 2 gallons of coco...all day long. Unless you're trying to reach the ceiling 5 gallons isn't necessary.

And aim your pH for 5.8..if you can manage a swing to 6.1 over a 4 or 5 day period (ie reservoir), even better. But if you make up your feed daily, I'd shoot for 5.8.

And don't pussy foot on the water...get the coco that's right around her wet...dry coco is again, a no no. Keep her moist (that's what he said)

Good luck friend.

Ok -but reason I have it in a 5 gal is because it's an autoflower strain and its recommended not to transplant and to plant in her first and only pot, which I've read best is 5 gallons.

Ok, I get the first and final pot for the auto...so you're right there. But to take full advantage of that coco, you're going to feed it every day, multiple times a day, and the bigger the pot, the harder this is when they're young. I kid you not, a 2 gallon pot of coco will grow a 6' plant all day long when you're feeding as you should with coco. So while you're right in having her in her final pot, she could go in something considerably smaller and still perform to her abilities. Never the less, there are a thousand ways to skin a cat and my way is not always the best for you or others. Good luck; you're on the right track.

Ok thank you so much for your help and advice. I will definitely uo my feeding schedule and make sure shes getting the proper nutes. Next time I do an auto I'll try a smaller pot for sure. I think after this I'll go back to photoperiod for a while to work on my growing lol

You're quite welcome.

Just an FYI...when you talk about upping your feed, what you want to do is feed more often, not so much a higher concentration of feed.

So like for me with a photo plant, it's started in a solo and fed every day...then upped to a 1 gallon and fed every day...once they really begin transpiring and taking on feed, I will up them to a 2 gal, and begin 2 feeds per day, and carry that on until the end...never feeding a super high concentration of feed along the way. Remember you're feeding it ever day, multiple times a day, it doesn't need huge amounts of food at once, because you're feeding smaller allotments more often. If that makes sense?
