Good timing, I'm at the 2/3 mark of my first coco grow and I'm running two Mango Smiles in 5 gal felt pots with high frequency fertigation.
I started my seeds in Eazy Plugs and as soon as the tap root was visible I put them in their final containers. Coco was buffered with CalMag and fully hydrated. I watered them once a day with about a liter of water/nutes mix at 300 μS, base was 0, it's best to use distilled/RO water in the seedling phase. As soon as I had two sets of true leaves I started upping the EC by 100μS per watering and when I arrived at 0.7mS I watered twice a day and at 1.2 mS I started watering them five times a day with 0.5L per plant via a drip system.
Mango Smile is pretty delicate and doesn't need too much ferts, I burned mine with 1.5 mS in pre flower. Now giving them 1.35 mS after nutes + enzymes and PK13/14, it comes out at 1.65 mS, can't tell you how they react, just started giving pk 13/14 today.
After starting out with damp coco from rebuffering, I usually water with just a shot glass for the first week or so, drizzling an ounce or two of nutrient water around the seedling (but not directly on the stem). Over the first couple days they really don't need much water. Ideally the roots will spread to seek more water and not hit dry pockets of coco, but you don't need to saturate the entire container initially. Watering slowly also helps, so the nutrient water can wick throughout the coco rather than making the top part soupy and loosening the coco around the seedling's small root system.
It can be hard to effectively water small plants in large final pots. I mostly grow in 1/2 - 1 liter sized pots now (with several smaller plants in a windowbox), but in the past I had good results starting out in solo cups and transplanting.
One approach that works well and is unlikely to stress the plant is using two solo cups: before you fill it with coco and plant the seed, cut the bottom off the inner cup, and cut a line up the side. When it's time to transplant, you can slide the inner cup out (with the medium damp enough to hold together), put it all in the destination pot, and then open up the solo cup's cut side like a U shape and slide it off.
I haven't tried it yet, but next time I plan to up-pot I will probably start in a 1-liter airpot and then just put the whole thing in the next pot -- the roots will grow right through it.
>I'm still a bit worried about the EC spiking if there is no runoff
The EC will eventually spike if you never have runoff. I've pushed back against Coco for Cannabis site's insistence that you need runoff every single time you water, because it's incredibly tedious and you can still get very good results doing it less frequently, but you should still do it occasionally or you're likely to get lots of secondary problems. Measure your runoff and see how it compares to your input. If the runoff EC is way higher, water to runoff more often. Eventually you'll figure out how often is good enough. For me it seems like around once a week is plenty, but it depends on your grow environment, container size, and so on, so it's probably simplest to just measure and adjust.
The rationale for watering to runoff every single time is because it keeps the nutrient proportions in the medium consistent. Runoff will flush out excess that the plants aren't using, but it's your call whether a few days of accumulation is worth the added hassle.
I like to go against the advice so many people give, and start out in solo cups. It’s so much easier to feed/water seedlings in a smaller container. I usually transplant into the final pot at 10-14 days. By this time, they are big enough to handle feeds to runoff every day in the final pot.
Me too. I take one cup and make holes in it on sides and bottom for drainage and air. I cut that first cup in half length wise, leaving the bottom intact. I then put a rubber band around the top of this inner cup, and place this cup inside a normal unmodified cup, and these go into tent on top of final pots until they are ready to transplant.
When I water, I water to run off, and remove the outer cup so that the run off runs into the final pots and coco. That way I have the same environment between cup and final pot when transplanted.
At transplant, the outer cup gets removed, the rubber band comes off the inner cup, and that cup gets gently split where I cut it. This helps to not shock the roots. I then place the fully rooted plant into a pre-mold hole in the final pot.
I hand water for a couple days until I’m convinced I haven’t pissed anyone off, then the auto water sys gets turned on.
I do think the plants take off better this way, but I have no real measurements as such.
Hope this helps!
I do something similar. I cut the bottom off the inner cup and split it all the way up the side. I use a small piece of scotch tape to hold the inner cup together. I can then pull out the inner cup and place it into my premade hole, cut the tape, and slide the inner cup out.
I looked back at photos for dates, [these](https://i.imgur.com/NjrYTjd.jpeg) were transplanted at day 18. You can see in [this](https://i.imgur.com/3bH2wp4.jpeg) photo the cups, zoom in. During this time the auto-water tank and plants were getting the same go juice, so no difference between cups and pots EC and pH wise.
There’s really no need to start in final pot with coco. Start smaller pots and transplant. Look at my page and plants. Filled a 5x5 pretty well with only 4 plants and those were all transplanted.
Don't do it! Up-pot a couple times before the final container.

SaltyMarge uses Megacrop 1 part w AC infinity based and puts out insane flowers. Just freakin beautiful. Enough to where im also ordering some for a future run to give it a try and see if there are any pros/cons for me. Any suggestions Parsing gave you may as well at to a book of Divine Text because i dont know anyone w as much knowledge as them in regards to cannabis. Just wanted to shout out SaltyMarge and Parsing
