I know I over watered for sure. Letting them dry out real good before feeding again. Rare Dankness site says you don't need to use calmag with their nutes. But I decided to add it on 3/16 when I fed. Hopefully the calmag and not overwatering will fix my issues. What do you guys think?


3/3
CalMag added to ro water to make 160ppm. 5.8PH.
Ran two solo cups worth of the 160ppm calmag water through each solo cup twice before planting seeds.
I'll admit i forgot to test the runoff ec/ppm after doing the above.

3/5
All seeds break coco.

3/9
fed at 250ppm rare dankness nutes
Run off: 440ppm. 5.9 PH


3/12
fed at 350ppm rare dankness nutes
Made sure to give a good amount of water to flush out the higher ppm from last feeding because seedlings looked very light/bright green.
Run off: 350 PH 5.9

3/15
fed at 450ppm rare dankness nutes.
Run off: 450 PH 6.0

3/16
Noticed the yellowing/browning crispy leaves. So I added Calmag. I realize that feeding a day after they just got fed prolly overwatered them but seeing the leaves look the way the did made me think i needed to add calmag.
260ppm calmag 7ml.
380ppm rare dankness nutes.
Run off: 640PPM 5.8PH

Seedlings don't like feed. They can get damaged in all sorts of ways. Just use plain water until they harden off. They don't look to bad though. Nothing to worry about. There will be plently of time for nutes later, and it's no big deal. Make up the correct mix of feed from the start, and don't try to do this ad-hoc. EZ.

I've always been told to feed from day 1 sprout with coco. Heavy 16 recommends it, Raredankness recommends having 250ppm of their nutes in the coco before planting the seed, cocoforcanabis website recommends it. I'e used heavy 16 in the past feeding from sprout with great results. This is my first run with raredankness and the whole no calmag needed confused me. No excuse for the over watering tho.

That's totally wrong Don't feed seedlings for at least a week. .

 

[rosinhood666]

Gotcha won't feed anymore seedlings for at least a week. Appreciate the feedback!

Do you have drainage holes in those cups? Make sure that when you start feeding you feed until you get 10% runoff. Consider adding perlite to your coco.

I have a bunch of drainage holes in the bottom of each cup. I always go to 10-20% runoff. I am 100% adding perlite when i transfer them to 2 gallon smartpots. My shop was out of perlite when i planted these, really wish i would have had it for the solo cups or started in something a lil smaller. I deff notice a difference in drying times w/o perlite. Always going to use it from here on.

PH is 6.0. Just noticed the leaves getting these dark spots, anyone know what this is? Thanks!

Looks like calcium, if they not feeding because of slow roots too wet too dry or any setback they can show deficiencies in all sorts of things when the elements are there just not available .

Never heard of the feed youre using , Id keep nutes around 200 ppm, back of on lighting demand if your lights are too close , foliar spray the same 200 ppm feed just before lights out but add some kelp and fulvic acid to the foliar . Your aim is to get them building roots and get metabolism going, make sure you have no bugs on them.

With 160ppm from calmag, you could easily have 100ppm of N.
You might be better using your tap to get some calcium and magnesium without the N. Then you could think about a 20% strength feed, as coco has things like N&P missing.
