Hey everyone, I’ve been germinating these seeds for 28 days now and they are severely undersized. I was just wondering if you think I should go ahead and kill them and try germinating new seeds or do you think I can get them back to health?
I’ve been reusing the coco coir/perlite mix these plants are sitting in for 3 grows and I think that maybe the last time I stored it away in a closed container it grew bacteria or something because I didn’t allow it to dry out enough and it was damp when I transplanted these seedlings into it. At one point a mushroom grew out of the one of the seedling’s medium. I also think there were some left over roots from previous grows. I’m just going to get new coco coir/perlite next grow I do.
For nutrients I’m using the FloraTrio seedling formula along with Botanicare Ca-Mg+, Silica Blast & Hydroguard. I might add that my water is RO water. Any help is much appreciated!
Thank you, I will give this a try as soon as they’re dry again. The pH runoff was originally at 4.1 but I kept flushing them with pH 9.5 water until the runoff came up to 5.7. Then as soon as I gave them pH 7.0 nutrient water, the runoff pH dropped to 5.0.
I’m having trouble keeping the pH in the 5.5-6.5 range for some reason.
Being coco you could water/feed daily the 50/50 mix makes it extremely hard to over water. Did you rinse coco prior to use? and what kind of perolite did you add some actually have fertilizer in them which would explain ph some
I’ll have to check when I get home, but no, I didn’t rinse it before I used it again. I’ve heard of people watering Coco daily but I’m so used to the water-when-dry method and have had good results.
I’m trying to decide if I should go to my local hydro store today and purchase new coco coir or just switch over to soil and buy that instead. Then I could transplant all 4 seedlings to a fresh new medium.
Otherwise I need to figure out how to fix my current coco coir medium’s pH.
