Is this ok for 8days

It is best to use liquid fertilizer and ph down with coco. I've never used coco. From being on Rollitup I've found that most coco growers water once everyday until run off. If you mix the NPK between 15-20% as recommended for outside, you can safely water with that everyday, drain to waste. Later in the grow if salt has built up in the coco, water with plain ph'ed water periodically with a good run off.

Hygro meter spikes can be gotten relatively cheap and you can stick that in the coco to get some idea of what's going on for moisture in the coco. Use the meter as a guide but go by the plant for the final result. Some of those cheap hygro meters are just that...cheap.

Seedlings come with their own fertilizer packet at birth. It should be good for about two weeks with plain ph'ed tap water, even though, a proper dose of fertilizer won't harm anything. Don't do anything organic in coco. Coco is set at 5.8 ph.

I would cut a piece of reflective plastic and put it around the base of the plant to hold down immediate moisture around the base of the seedling. I cut them 5" x 5" with a slit and a small diamond shaped hole in the middle to accommodate the stalk.

Smart. Good Advice for this thread.

top Notch right there. nice fish pebble. leaves strait and taut. uniform. all you can ask for at this stage.
Thanks man, lol its a top layer of growstone cuz I think I killed a couple fungus gnats so I figured better safe than sorry, it's happy frog on top with maybe half and half hf and ocean forest through the rest. And just cuz I can't help it heres what day 10 was

I'm a total noob at cannabis too, but I've been growing veggies for 2 years now, here's what I've learned.

From seed, I find it works better if you pop thr seeds first in paper towel. That way you can get the taproot planted right side down .

I've never added nutes to any sprout until I see the first true leaves either, as the seed has enough nutrient to get it to that stage. About the only thing I ever add from start is myco.

That is a little small for 8 days, but my advice is stop fucking with it. Plants want to grow, period. Your job is to guide it on the way. Water the seedling with regular water for now till you see a bit of growth. Then start your veg nutes at half strength. If you leave the thing alone for a couple of days it should recover. Just add water till wet every other day. Once the top layer of soil starts looking dry, add more water.

I think 1/2 strength and 1/4 strength can only be based on nutrient brands only. Each nutrient brand has different concentrations, some weaker or stronger than others. A more accurate way of measuring feed is having a tds/ppm meter. Seedlings have enough nutrients in the cotyledon leaves for at least two weeks. Using only water in coco causes osmotic stress. Ive heard to NEVER use water only in coco. If you decide to feed, feeding in first week 110ppm (depends on what scale the nutrient company uses, 500 or 700) should be fine. To OP, none of my seedlings at the current moment, in coco, are drooping like that. Your coco looks really dry on top. I feed every other day or let it dry out some. As others have said it helps build roots. Treat coco like soil for the first week. Then if coco perlite mix is good you can water every day, sometimes more depending on pot size.

I think you posted on my grow log, but that's what I do. It's working for me, but ymmv. My water comes out of the tap at 200ppm, so it could be that's what's helping me

I got the tip from the farmer side of the family: don't over-feed, always start fertilizers at half strength or light feeding schedule. The goal is to give the plant JUST enough nutrients, but not too much. Better to have too little (so you can add) than too much (because you can't take away without flushing). Seems to be working for me so I'm going to stick with it until it breaks or I get a few more grows under my belt.

With regards to osmotic shock.. i couldn't tell you. I know that once you water a few times the nutrients start building up in the medium, so the odd watering with just plain water shouldn't hurt. I mean, that's the point of coco, right? It's a buffer. And the plant is a plant, not a faberge egg. It wants to live and grow and diesn't need 100% optimized conditions to do so, because such conditions never exist in nature. I'd have to work harder to kill the things than I would to keep them alive.

I use canna, my tap water is around 75ppms out the tap. I add, in one cup, 2 drops of a and b both, and the ppm goes to 150ppm. On a larger scale, which I havent calculated, might be too much for a seedling, maybe. I only have one "successful" grow indoors, two outdoors, so im still new to indoors. Having things dialed in, is what gets yields up, heard it through the grapevine.

I've found that it's less problematic to plant seeds in 2 x 2 x 4 inch nursery pots of soil. A decent soil has everything a seedling needs. When the roots start coming out the bottom plant into three gallon pots of 100% coco prepped with 1/4 - 1/2 strength nutrient solution. The small amount of soil doesn't matter. You don't need to water young plants everyday either. Until the roots fill out you don't want the coco too wet. Many people over water in coco with seedlings because they drain to waste on a tiny plant. That keeps the coco too wet when there isn't a large enough plant with a root structure that can actually use that moisture.

How many times did you water before you had your problems now? Did you use nutes? Like many others have said, treat coco like soil for the first week. That wet and dry cycle encourages root development. Your autos are stunted and it looks like yield will be affected negatively. We live and we learn man, thats life, come back for more!
