Junior Grower First Time

This is the 6th day since the sprout, and no-name looks well, but the journal must go on, daily.

Not much rain, temperature at 29 celsius, 60% humidity.
 
Looking good Grower! :thumb:

Welcome to :420:

Your soil (can you tell us more about it?) looks wet. You’re probably a good candidate for coco - it’s impossible to overwater. It does require pre-charging with CalMag, a lower nutrient dose, and daily watering.

Even better is a passive hydroponic method called “hempy”. Like coco, it’s essentially drain-to-waste, but unlike coco, there is a small reservoir in the bottom, provided by a single hole about 1” to 2” up from the bottom (depending on the size of the container - 1” in a Solo cup, and 2” in a 2 gal bucket). This reservoir helps prevent the need for daily watering, at least early in the grow.

If you’re interested, there’s an entire Hempy community located here:

Ultra Dawg (Day 86, flip + 18) I potted up a clone of Thin Mint GSC today, the latest of my hempy plants, and dropped a new seed in another hempy cup, a Blue Dream, the genetic product of MagicJim's talented hands. :battingeyelashes: :Love: I'm hoping I can make the Blue Dream as healthy...

The soil does look wet Grower. Seedlings can easily die if in too wet of a medium for too long which is why it's better to only give them just a bit less than enough to wet the immediate area. This also why it's best to keep seedlings in very small pots. It's better for them to become root bound than to die from damping off.

No offense FelipeBlu, but I've seen too many newbs fail in coco, usually due in part to not properly charging the coco. Literally every other media type does not need to be precharged. I've been in potted rock wool for many years now and I don't need to buffer it. Coco, being organic in nature means the grower needs to make other contingencies when planning the feed as it has a lot of K, so you have to diminish the K in your feed. I'm not saying coco is impossible, but it's definitely not a good starter media.
 
Perlite I can get behind, especially in this situation, lol.

Yes, it is. The last time I water it was 3 days ago. I better let the soil dry out, and start your 5-10ml way to water the seedling everyday. I start big pot, that's a mistake.

Wow, i didn't know you can grow on pure perlite, i assume you got to feed the plant consistently? How about the PH? Is there any difference compare with coco coir?

Yes, you feed with every watering, but you start off pretty weak. Ideal pH is 5.8, but I use vinegar and get a 5.6 to 6.0 drift in 48 hours. You must have a good pH pen.

Hempy is a method, and coco, perlite, rockwool cubes, aquarium gravel, and pumice, have all been used.

The idea is that the mysteries of growing in soil are removed, and you are directly responsible for providing what the plants need. The benefit of hempy, over growing with coco in a traditional pot, is the reservoir. It can save your a$$ sometimes.

Is hempy like a bato bucket, in that each pot has a builtin sump that holds a bit of the feed water for roots to wick out of?

I like rockwool b/c it too can't be over watered, but if you mistakenly don't feed it for 2 days, you don't get penalized. It's very forgiving and airy, yet retains a lot of water so the roots grow in the flavor savers, lol.

Yes, but fully manual in my present case. :cool:

An automated feed and drain system would be very handy for when I (am likely to) have to leave town during flowering.

8th day, I noticed the color is not green anymore, it is lighter than green now. It happens from center of the seedling and spreading out.

You might not see the color from this photo, i think the phone's camera add in the color for me. Do you guys know what cause yellow from center?

This photo taken from another phone which I feel the color is more accurate to what my eyes saw.
 
Until the cotyledons wither, the seedling won't uptake any nutrients from the soil, so stop thinking this is something you can change. The very minor discoloration is nothing more than a growing pain. The seedling has to grow out some roots and foliage by combining a little water from the media with the contents of the cotyledons. For the next 2 weeks, there's not much you can do except let the soil dry out, then begin watering only the immediate area around the plant, maybe a 1 inch (30mm) radius around the plant. This will ensure that the tiny bit of water you add in itself is quickly drank or evaporated which would then put you in position of needing to water the same small amount the next day, and over time you'll gradually increase the amount of water you add.

This is what makes the roots grow though, the lack of water. If the media is constantly wet, roots won't hardly grow and the result is the plant above ground won't hardly grow.
 
How much light are you providing and how far away from the pot is it? Your pics look fairly dim.

There's grow light in tent. Although I not sure how strong it is, it write 360w when I buy it. I search on internet that the light should stay 25-30 inch above the plant.

The reason I took plant photo on a relative dim light is because that's the most natural color it'll show (ceiling fluorescent light). I always put it back into the tent immediately after daily photo session.
 
I understand now. Taking photos in blurple lighting makes for horrible photos.

Thanks for suggestion, I will stick on your plan now.
 
9th day. The cotyledons start to become significant yellow and looks like they are going to wither. But pair of leaves looks good today.

Although the soil looks wet, but it is dry. I put my finger in soil and feel the weight. And it's been 4 days I never water it. I will start water the plant the way @Skybound suggest. 5ml-10ml around the seedling. Everyday.

Your soil still looks very moist, I would wait another 2 to 3 days before starting the small dose of water. You really want the top inch of soil to crust over which then gives you some insight what the wetness level is below that. You can poke a finger hole in the soil away from the area of the plant to better gauge the wtness, but I promise, you want it more dry than wet. Seedlings more than anything are especially prone to damping off from a mold growing on the young stem where it meets the soil. If you feel the need to wet the media despite our warnings, that's fine, but consider taking a capped ink pen and poking a hole at an angle that will intersect with the tap root about 2 inches (50mm) below the surface. The tap root will be better equipped to deal with your affinity to keep the ground wet, but where the stem meets the soil you really do want to keep the ground dry, at least till the stem thickens up and gets woody.

The cotyledons will be there for a while. Here are my seedlings that I posted pics to my Herbie's Bulk journal last night. My cotyledons are just now starting to wither almost a month in to life.
