[Stonerbudz]

Really hope all works outfor you will be watching along if cna provideany other information

In coco all you need for seedlings for first 2 weeks is cal mag and water and you will be okY and the calmag is only used at 1/2 dose than after first week go up to normal dose

hey brother i’m not a coco grower so can’t really help much, but there lots of growers who use coco and are very helpful..
be patient they’ll be here

This is only my second grow in coco but my first was wildly successful. 1.5lbs from a 2.3x2.3 using 70% coco 30% perlite.

My seedling stage for the first week I hand watered once or twice a day with a calMag solution of 5ml calMag per gallon then feed them a seedling solution at around 200ppm. Two weeks of that I slow up my PPM to around 600 with a veg solution.

Now to note I didn’t use worm casting so this will be a bit different for you. I also use an auto fertigation and auto drain to waste (DTW) system and feed from 2 times a day to 5 times a day in flower.

Update: finished with the transplants. Luckily no root issues. Actually pretty dang thick they were.

Hey thank you for this info. I’m also trying to use an auto drip irrigation system (see below) how long do you allow your pump to go for when watering per feeding? Mine gushes water but I can’t find the gph of the drippers I got anywhere on the web.

That worm castings might add some nitrogen so u will see deficiency less earlyer in my opinion

Yeah I use a halo system with shut off valves so I can control flow. I have mine going for about a minute 20 to get about 10% runoff.

Hopefully you can sort of see it tee off the white picket in the back. I have that coming from a 27g res.

Should I continue this thread for the rest of my grow or is there a specific section for updates?

Update: They grew pretty well for the last few days of this week so I decided to top them. I topped all at the 3rd node as recommended, and I tied each branch down as shown. I plan to do the main line technique. I watered with RO + calmag just to be safe and see how they heal. Then I plan to water with reg nutes the day after tomorrow. Also I took one of the tops to clone (used clone x rooting gel and covered with a sandwich bag dome)

But I did notice that one of the plants had this. Is this magnesium deficiency? I have crystalized mag says add 1 tsp/gal. Or a different deficiency??

Correction: this is the same leaf I originally asked about at the beginning of thread but it doesn’t look like it’s gotten better or more green. I’m also showing the other side which looks worse. I did leave the light on 24hrs for 4 days by accident. Is this light damage?

that’s from improper watering, keeping the medium to wet..
also i notice your a helicopter parent, stop it!.. just let the plant grow, you’ll cause more harm to it than good..

 

[gristle]

That leaf will not heal itself, focus on what the new growth is looking like. Don't make any adjustments yet.
I would personally take the clone out from directly under the light as well, maybe just set it on the floor.
Haha, definitely a helicopter parent, but that will be an advantage once you gain more experience and know when to get out of your own way.
Good luck!

think that clone is a goner, did you snip and place directly in a glass of water until planting?
