Long ago I used to run coco….. did it all wrong. Went to soil for a few years and now back to coco. With the ppm side of coco everyone seems to suggest keeping the ppm low (450-600). With ro water I’m running silica blast, calmag, liquid karma and pure blend pro grow and bloom. By the time I add everything there’s only room for 200 ppm of grow. Doesn’t seem right to me. I’m getting 2 parts n from my calmag but it doesn’t leave much room for the other macros. I’m flgetting really slow growth. My roots look nice and healthy but in soil my plants would be 2 times the size by now. Any advise? I have a 3 week old seedling that is a little pale and some twisted leaves. No burning at all but a little pale like it needs more food.

Pics?
I’ll throw some up later on today.

Mix all your nutes, then add ro water to dilute it down to desired strength.

I use gh flora series nutes (micro and bloom only), with 1.5 grams mgso4 per gallon. I haven't needed calmag in a long time, so I can't really answer that question.
I used the 3 part in the past and never had a problem. I’m thinking that the botanicare is lacking in some places. I ordered some micro blast thinking maybe I’m missing some micro somewhere. My room tops out at 74 degrees (70 as a low) and I was thinking that may be a little on the cool side for a seedling.

What size containers and how often do you feed?
What size containers and how often do you feed?
I’ll throw some up after I get home. I fed every other day and switched to once a day last week. I’m using a pot a little bigger than a solo cup. It takes so little water to feed it that it’s getting a ton of run off. Ppm is 375 and ph is 6.0

i am on my second coco coir grow i am on day 28 of the plants life and i feed at around 1200ppm every watering. 600ppms seems kinda low i give them 800ppm's worth of base fertilizer and 400ppm's worth of additives. maybe im overfeeding? honestly i might be giving her too much lmfao im not sure.
when the plant was a seedling i would give it 200ppm's of base, when it hade 2 to 3 sets of leaves i would give it 400ppm's worth of base, and when it had more than 4 sets of leaves i started giving it 600ppm's of base, after it got a bit bigger i started giving it 800ppm's of base and that's were im at right now. i dont plan to increase the amount of base i give it anymore.

Every plant is different. Feed every day in coco. Play with your ratios. I have fed 400-600 for entire grows. There are people out there running 1500ppm. Find what works for you and your plant. Good news is that with coco, it usually shows up pretty quickly and if it needs adjusted, the corrections also show pretty quick. Don't get so hung up on arbitrary numbers that you neglect what the plants are telling you want/need. The smaller the container, the more often you are going to want to feed them because they will suck that thing dry in a few hours and dry coco is the enemy.
It’s definitely not getting dry yet. I figured I would be water multiple times a day when it starts sucking it up. I think I’m definitely getting hung up on numbers. When I ran coco before I ran it like soil (mistake). Everything would go great in veg then I would start getting buildups and throw the ph way off. I’m going to up the base tonight. If that don’t work I’ll start adding micros (I plan on doing it anyways but I want to see if that’s the problem before I start adding it). If that don’t work I’ll up the temps 5 degrees or so. I really could care less if the seedling dies, it would help me more in the long run to figure it out. I’ll post pics and a conclusion.
my plants looked like this about week 4 or 5 from seed in soil. I’m in week 3 and it’s still a feeble seedling. Pale and twisty.

I had a couple beans pop and do this this last time I started some seeds. I just chalked it up to bad luck and culled them. They got to 3-4" tall and just stalled out while the rest of the beans took off as they should in coco. So, that could also be your problem.
I’m going to see if I can pull it out of it. No biggie either way. More of a learning project now. I’ve actually had some problems with these seeds in soil. It’s blueberry glue. I can’t remember the breeder off the top of my head. It is super blueberry potpourri smelling when it comes out good. I have a couple autos running just to use them up. Freebies from a seed bank. They seem fine with the same air temp and humidity.

I've never owned or used a ppm meter.
Old school style. I feel like I don’t understand without seeing numbers. No natural green thumb here lol

honestly like tch said maybe its just genetics,
this grow i started with 3 plants from seed 2 of them were runts and the third one which is the one you saw in the pic was growing fast as frick!.
its 28 days old from seed.....
also on my last grow i was using a 3 part base fertilizer micro grow bloom(not made for coco) and my plants in the seedling stage were healthy but once they entered veg they were growing slowly and some of the leaves started going yellow on me
so i switched to advanced nutrients "sensi coco grow" 2 part base and my plants exploded in growth.
my next grow im trying mills fertilizer's but so far with advanced nutrients in coco ive had very explosive growth.
i start at 200ppm and slowly work my way up to 800ppm on the base fertilizer as the plant grow bigger and i add 400ppm of additives on the side.
sorry for spam good luck with your grow boss man!
