Sickly Blueberry muffins

Not sure why I can't grow this strain. I've popped 2 blue berry muffins from humboldt seeds. Both of them seem diseased from early on. Hopefully you can help me diagnose what's going on here. I'm growing in Coco Coir ph'd to 5.7-6.0. My nutrients are fairly simple. I use Mega crop, calmag and sometimes kelp if I remember. Pretty simple schedule that I've been following for a few years now. I have 2 other strains that I'm currently growing at the same time, it seems to be a blueberry muffin specific problem.






Any feed back appreciated.
Thanks.

That coco looks different than most.
Do you always feed to run off, and how often?

Hi, thanks for the reply. Good eye with this coco, its kinda crap. It's a little clumpier than most. Seems to be a coco shortage in my city. I've been stuck with it for a few grows now. I have to give it a really good ph prewash to remove the salts and calmag bath. I mix the coco with about 30% perlite. I always water to about 10-20% run off every 3 days. I sometimes check runoff PPM and it's usually close to my inputs. I know watering every 3 days is going to make some coco growers jaw drop, but it's been working decently for me for years with a variety of different strains and coco manufacturers.

Not the best grower but they do alright.

You are in coco and water every third day? I grow in soil, so not a pro… but seems I see coco growers feeding 3 times a day! Maybe they are famished?

I knew that my watering would get attention
You are correct, a lot of coco growers fertigate daily and some multiple times a day. I'm not in a position to dismiss it as the root cause of my current problem, but it would be the first strain of many that it has had such a negative effect.
Do you feel like I'm off track with fungal or a disease problem? I know I've been doing things so long a certain way that I'm bias and going to have to get beat up a little if that's the case.

Maybe try growing that strain in potting soil?

Hey thanks for the reply. It's a good idea but if it comes down to me having to switch up growing media I will just scrap the plants. That may be my only course of action anyway. Coco has been a great growing media for me up until this point. I've grown a few years in soil and I find coco to be the easiest way to grow for me. I can water all my plants in different stages on the same day and not have to worry about over/under watering.

Can we see some pics of your other healthy happy plants?

Changing your growing medium can be a hassle, Its understandable why you would prefer to scrap the plant.

There is a vid a few posts up. But here is a pic of what else is growing. The two plants on the front left (still in veg) are the same age as the sickly BlueMuffins. Not super "healthy happy" but not really anything I would typically worry to much about either. One is Grand daddy purple, the other cherry pie.

Dang, big difference. Beautiful girls. I would also be incredibly frustrated with that blueberry strain. Maybe you should try a different seedbank?

Yea for sure, it was my first time with Humboldt seed company. They seemed to get a lot of props around the forums until recently with their triploids. However, I don't want to throw the seed company under the bus for what is probably a me issue. There have been some nice grow journals of the strain. Guess I'd just like to know if this strain is just susceptible to disease or is this some sort of nutritional lockout that I'm not giving her what she needs. It's so sickly lookin I just can't tell what her issue is. It seems a little to drastic to be a calcium issue imo, the leaves are pretty light green so I've been upping the feed slowly. I see some of the leaves are taco'ing but I don't have them under intense lighting. Around 15-20 inches under 75 watts of samsung leds. I'm pretty vigilant with coco and keeping the PH in check. I'd like to blame the F'ing gnats, but I'm not sure they can do damage like this. My gnat battle could be it's own thread alone. Been fighting those f'ers with Mosquito dunks and Neematodes.. Pretty sure they've grown to love the mosquito dunks.

I haven't done a ton of photo period, mostly auto's. I've been running them 24/7 in the veg room. I could throw a timer on them for 18/6 or something if photo's require down time. However my veg room has a lot of light leakage that I can't really fix right now (open basement). Not sure if that would be an issue during veg with photo period.

Some plants are finicky with feed. I had a bomb seeds do that. I grew it out… was super ugly with small yield. I couldn’t fix the problem. Don’t know…
