Lime Green

[HI808]

Hello fellow growers.

Through a series of unfortunate events I am looking for incite to a problem I may or may not have.....

The project.
4= Seedsman Northern Lights Autos
2= Seedman Alaska Purple Autos

The set up:
4x4x7 custom closet build, insulated with 1" foam topped with mylar for reflection. Excellent air flow and very stable temps and Humidity.
Average 78 T and 55% H. Directional air flow with 3 6" fans. 1 fan set facing East at 8" from the ground, 2nd fan is North 16" from the ground and the 3rd is West at 24" from the ground. All plced in corners. I change the direction every time I turn of the lights. (not sure if this matters but as I said air flow is excellent)I also have a 6" water cooled intake fan, it blows in cool air. Then a 6" extractor fan with Carbon filter.
Lights running 18/6.

Light is a spider farmer 600 with veg and bloom dimmer. 200 watts from the wall. The height is currently set at 30 inches above canopy. Power is at 100% on veg only.

My problem started by rushing. I soaked the seeds in water for 18 hours until they sunk. I then transferred them to a paper towel. 6 hours later I put them in rock wool cube, 2x2. I felt like rockwool might be better..... Should have left them in the paper towel.
I made my own home made humidity dome from a 14x6x5 Tupperware trey. I was able to monitor the temperature and humidity, average was 82 T and 70% H. At one point the heat ran away on me and hit 88, not sure if that was the cause of the problem?
After a few days 4 seed became seedlings and a day later the other 2 came to life. Beginner mistake number 2, I added my 600 watt light at 20". I started at 50% then after 2 days gradually moved up to full blast.
After 5 days I decided to transfer them into 3 gallon fabric pots. MEDIUM is 70% coco/20% perlite/ and 10% clay pebbles.

BY day 7 they appeared stunt, I was only using water PHed to 5.9. I may have over watered. I started nutes on day 8. 1ml. Orca/ 2ml. Cal mag /1ml Grow/ 1ml. Micro/ .5 Bloom. PH at 6.0.
BY day 10 I started to see noticeable growth on 2 and small growth on 4. I waited 3 days then feed again the same amounts. I waited 2 days then watered only, which was today.
All seem to be growing but now I am noticing a lime green not quit at yellow color on the current set of leaves that is coming out. 3 sets on most.
Is this lime green color bad? They were a rich green until yesterday.

Have I completely screwed these up or do I have a chance to recover from the stress I caused. I feel like they are small unfortunately I don't have pics at this moment.

Any help would be greatly appreciated.

Unless they’re brown and laying on the ground, I’m sure they will recover! Pictures would definitely help to see where they’re at for they’re age.

Always try and water with nutrients in coco! Using plain water will mess with the coco’s CEC, and then your feeds will be unbalanced, as the coco will take what nutrients it needs to fill the cation sites before the plant gets access to it.

Did you pre-charge your medium before you transferred the cubes into it?

Photos would help, and I'm about to turn in, but for starters, your growing in a hydroponic medium and treating it as soil.

Coco has no nutrition, it is a feed every time medium. The pale color sounds like under feeding as well. Overwatering in coco is next to impossible. Just finished a coco run, started at feeding once a day, by mid flower was at every 12 hrs.

I did not, I only PH ed the water to 6.0. I did use Orca in the begining and also in my last water. It was not water only, it had 1ml. of Orca. Not sure if that matters.

Thanks for the info, Its hard to get proper info on this project. I have spent countless hours on youtube and weetube. I was Planing on watering and feeding daily then I came across the grow boss. Even though he seems like a big Prick, it made alot of sense how people with bad pictures looked to be over watering, even in coco.
If I decide to water every day, what ppm do you suggest. I currently sit at 490 to 1 gallon. If I water Daily would you suggest I run at the recommended 1000 ppm every day?

Thank you

These are not the best pics, but you can get a idea of what Im working with. Also, my coco mix is much better than it looks. I recently added a small amount of coco only to top the rockwool cubes that started to show.

If I am correct, these ar e at day 12.

Guessing your seeing a couple issues here. No feed in your mix (for the most part) and unwashed coco, and... did you soak the rockwool plug? Most coco out there says that it's been rinsed. Due to where it comes from, most is rinsed with salt water. This needs to be flushed out prior to starting, as the salts bind anything you put in.

At this point we need to see how far off everything is. A pH and ppm test of your medium is needed. I use a shot glass, take equal amounts of the coco in the pot, and water. Let set 5 to 10 minutes and take readings.
Coco should be pH 5.5 to 6.2, and ppm under 200 up your feed, over 800 back off some. If the ppm is way high, flush medium and reset to correct values.

Thank you for responding.
This has proven to be a very informative test and is most likely the root of my problems.
I did soak the rockwool cubes in water Phed to 5.5 as recommended by many on YouTube. I also prepared my coco with water PHed at 6.0.
The coco I am using in Canna coco bricks. I did not rinse and after seeing this test, I should have.

I tested 2 ways, 1 in my fabric pots and 1 in new coco only, never added nutes to this.

Results where :
In my pots PPM was177 and PH was 6.5. I did do a water only yesterday and I have only feed with 490 ppm 2 times prior.

The coco by itself was PPM at 334 and PH at 6.7( PPM crazy high for new coco?)

I am assuming this was the big problem. MY PH was way to high and from the beginning the coco was saturated with a super high PPM?


From the pictures do you think I can complete the grow with a decent end yield or should I expect low numbers ?

I am planning on feeding at 5.5 for the next 2 weeks to try and balance the PH in the pots. Is this correct or should I do some kind of flush? I believe I have severely stressed these plants already? Any input on how to get these girls back on track would be greatly appreciated.

Also, IT is very hard to get accurate lighting info. I have my lights at 30" from tops. Both are set to 100% on Veg.
My lights are 600 watt Spider Farmer LEDs. 203 watts from the wall per light.



Thanks

Lighting is kinda a rough one given all the options. 30" sounds safe to start. Ppm is high in fresh coco, unless its "pre buffered", then its probably on target. PH is way out.
I'd probably mix up a mild nutrient solution and flush. This is where coco shines, if you have an issue, flush the medium and reset to correct values. Soil we adjust over time.

So, flush with a mild feed, continue to monitor the pH and ppm, you'll see it come into range. Then continue on. Never let coco dry, it will cause major issues with pH and nute exchange. Till flower I feed every day, in flower every 12 hrs. Many on recirculating systems will feed every 6 hrs.
