Some additional information. 2nd year grower. Looking for successful growth. I have a 5 gallon bag and a 3 gallon bag. 100% Coco Loco. Sour Tangie seeds. Using GH flora series with a few add ones. The seed in the 5 took off. The 3 was slower to get started. It's just about caught up. I'm 8 week in. Was feeding every 4th day. Now every third day. Don't think I'm over watering but...Growing in a 4 x 4 x 60. Grower Choice ROI- e420 with Mars- Hydro UV, IR and Blue add on lights. This basically my first none autoflower. Just waiting for it to get some height before flipping.
Mainline looks good.
I'll just say that if you're going to grow in coco and use synthetics, then you should just grow in 100% coco (e.g., coco/perlite) and not Coco Loco, which is about 50% coco and has fertilizer and other shit in it.
In coco that doesn't contain "aged forest products" or fertilizers, you just water it with nutrients every single day, at least once a day, and the plants will take off like a rocket ship and realistically you never have to worry about overwatering.

Thanks for your insight. The Coco Loco is not cheap. That will be a savings. Do you also start seeds in the same manner? My first grow a few years ago I ordered coco coir and perlite and went that way. Not sure why I changed. Well, I do know. Reading too damn much speculated information. Lol.
After the coco is properly rinsed and charged, I do a final rinse with 0.4-0.5 EC nutrients. I take germinated seeds and put them in the coco/perlite in solo cups.
Once the seed pops up from the coco, after 24 hours I'm feeding nutrients at 0.4-0.5 EC. Some people wait for 3-7 days before feeding nutrients because the cotyledons will provide food to the seedling, but hitting it the next day with nutrients makes the growth take off during the first week, which makes it possible the next week to...
On day 8 or 9, I increase the EC to 1.0-1.1 EC and top out at around 1.2 EC in veg, and top out around 1.3 EC in flower. Always feeding multiple times per day - seedling to harvest. If one feels sketchy about feeding at least once a day during seedling, increasing perlite to a 50/50 ratio will ensure no problems.
Thanks. Great information. This should definitely step my game up.
I had been filling a gallon jug with my tap water then adding gh trio as per their chart at the medium level. Didn't have an ec meter. I've been using the meter and have had to add quite a bit more tap to bring the ec down to 1.2- 1.3. Is there a better way to mix your nutrients? Glad I didn't fry my two girls. Looked good before and still look good now.
Keep in mind that GH charts etc., are for general plant growth. Tomatoes, for example, can handle an EC of 5.0 so I think just following the ratios on the bottle work best to keep the NER (nutrient element ratio) of the line balanced and then use EC levels appropriate for cannabis.
NER for GH Trio:
1/1/1 micro/gro/bloom for seedling and early veg (higher EC for early veg but still 1/1/1)
2/3/1 micro/gro/bloom for mid/late veg
2/1/3 micro/gro/bloom for flower
These are the order in which they should be mixed. Add each separately, stirring/shaking between each bottle being added.
So EC levels for those stages:
0.4-0.5 seedling
1.1-1.3 veg
1.3-1.6 flower
What is the starting EC of your water before adding nutes?

You have received good information from other members. Coco is a brilliant medium to use another good source for growing is cocoforcannibas.com plenty of information on the subject. My current grow is 5 autoflowers in a 4×4 all started in 3 gallon fabrics 70/30 coco/perlte hand watered once a day now at 11 weeks twice a day. My ec has been 1.0 from week 2 ramping up to 1.3 at week 11 and they have a bit of nutrient burn but nothing to worry about.

I just purchased two new testers.
I just purchased two new meters. HM 80 EC meter and HM digital pH meter.
My tap ( well water ) read oo to start then I got these readings
uS--- 55
Ms--- .1
O.5 PPM--- 26
0.7 PPM--- 35
pH--- 8.9
I have two gallon jugs I mix in. Day before I was mixing nutrients and keep pulling some off and adding tap to get down to 1.3...1.4
Just to check the second jug I'd been using to pouring off the first jug measured at Ms--- 1.6 and uS--- 1623
Thought that might be higher than that.
I was starting with 1 gallon tap. Added
Micro-- 4.7 ml
Gro--- 3.8
Bloom--- 6.6
CalMag--- 1.9
The was the medium GH feeding chart. From there I added tap to get to 1.3.
Plants are looking great!
The only comment I'll make (I am capable of not writing reams) is that the plants look very green. That could be just the fact that the pictures were taken in natural light but just wanted to run that by you.
Keep up the good work—this looks like it will be a great crop.
Here are some 11 week photos with the lights still on. Used some pants hangers and cut the paper tubes to fit between my stems.
Just use Ms in the forums. If one says 1.6 EC, everyone will know it's Ms. If you say something like 1623 uS, there is a chance someone will quickly interpret that as PPM.
Plants look great! On your next grow, you may want to consider using the ratios listed from the back of the bottles. It's just way easier to pull something like 4ml/6ml/2ml (2/3/1 ratio), but one dozen two half dozen or whatever that saying is.
I'm not sure which order you're putting the calmag in, but always put calmag first before the micro, gro, bloom nutes. Also, if you add silicon (e.g., Armor Si) in your next grow (which you should because you'll see a noticeable difference), add that before the calmag and let it bond to the water for at least an hour before adding the calmag.
I also highly recommend the cocoforcannabis website mentioned earlier, as well as the interviews he did on the Garden Talk Mr Grow It podcasts.

Oh thats not natural light ill hang a xs 1500 on 25 per cent to take pics the plants look weird under the pro grow 630. Yeah I find with canna coco a and b + cal mag the plants stay very green until you start reducing ec input I just finished a week of low pk boost cut cal mag and have started ec reduction. 4 out of the five are sour diesel autos with there sativa dominance could be a while till they finish. The plant in the middle could be an imposter as its very different from the rest and is not to far from completion.

Might be screwing up but I started this grow using the GH charts for medium growth. My pH and ec meters were not functioning properly. Plants seemed to do ok. They were getting too many nutrients. Purchased new meters and switched to the coco for cannabis chart. Plants not as dark green but seem OK. The gh chart had me adding calmag after the trio. Not using Si at the moment but did move calmag to the front-end. Trying to get into some sort of groove with the nutrients. Looking at the 1-2-3, 2-1-3 sort of ratio to make things a bit easier. I started converting oz to ml and using a digital scale. A pain but it did work. So , please, everyone call me out on the dumb shit. Lol. Still having fun.

Ive been learning you can overwater them. Mine will gutate at 4x a day fed no circulation 80F 55rh. So I upped circulation with boxfans lowered rh to 35-40 but fed 12x a day with pots sealed in garbage bags. If no bags 12x a day barely does it if rootbound enough. Otherwise 8x a day less roots/veg time.
If rh passed 40-45 it would gutate early flower on leafs. The overwatering can also cause darker leafs from the extra nute uptake. So I was always on the line pushing it. I just kept rh as low possible and most boxfans on 3/3 setting above bar lights.
It did help but really learned from another user here that I was overwatering. Gutation I think causes it, when I had it there was water droplets somewhat sappy all through out the buds. So two wks into flower taking advantage of bags helping with dryback, 55-65rh sometimes 70+ and no gutation at 6x a day fed.
Leafs way lighter color no N tox whatsoever at 1.7ec. So overwatering can actually cause some serious issues, what do you think? Kinda the latest ahaa moment.
