That would be a nasty job lol, i'm located in the basement where there is no water evacuation

Also don't ever do straight water, you will throw off your caution banks. Cut nutes down to a quarter of what you have been currently feeding them. Once you get ec and ph coming out the same as what's going in then try a Ec of maybe 1.0 or so

Too late for that i first ran some water through them and than feeded 1.0ec so it's pretty close to what you say

this is the results after the plain water again to compare:


and these are the results after 1.0ec feeding before bed:
Plant 1 >> 6.4ph in >> 5.8ph out - 1.2ec
Plant 2 >> 6.2ph in >> 6.3ph out - 1.2ec
Plant 3 >> didn't touch that's the one that is doing great and didn't get the water only either.
Plant 4 >> 5.6ph in >> 6.4ph out - 1.2ec

Here is a master coco grower, explaining how to feed them. Skim through first 10 pages quick, which is mostly pictures. After that he explains using small containers to start, and wanting them to need to be watered, before feeding.

It's my first time so i don't really know what healthy roots look like.
I can see them tops coming out underneath the pots tho, they look very healthy and snow white.

I let the surface get a little dry before watering. By the time they go into flower they will need to be watered twice a day, and almost impossible to over water at that point, unless you have been over watering throughout veg. That is why air pots and smart pots are prefered. They help it dry out quicker and prevent root circling, by air pruning the roots.

I'll defenetely get better pots next time

Actually further on, I think about page 10, but have not read in awhile, he discusses needing to let vegging plants dry out somewhat, or poor root development.

You will know when you up pot. If the coco falls of the ball, then poor root system.

Went back and looked, yes that page towards bottom -

with that said, multifeeds only work with A. an undersized rootbound pot and B. a thriving and thick root mass...if you throw and under developed root system in too big of a pot and try it , its a recipe for disaster...roots need dry cycles to thrive and expand...once root bound is when you want to start multifeeding...during early veg I use a wet and dry cycle and only start muti feeds in the final container...I do this to encourage dense roots mass as the dry cycle make the roots branch out in search of water...keeping them wet early on will not and will retard root growth ..once in final containers I start 2x a day and bump up as necessary to keep the medium wet...by flip im running 6x a day...this is with pure coco..if cut with enough perlite, once could multifeed from the jump with similar results

1 is looking worse today, more droopy than usual, also branches of leaves looking redish:

How high is humidity, and do you have good air circulation?? I just got f-ed over by Fusarium Wilt, which will manifest in bud rot a couple of weeks before harvest. Purpling of stalks and leaves, and yellowing early is a sign.

looking back @ the last 2 weeks humidity is always between 49 and 57, mostly around 52-53.
temperature in last 2 weeks is between 26.1° (79°F) and 24.9° (77°F), mostly around 25.5°C (78°F)
canopy temperature is always slightly higher, not much tho.

there are 2 fans in the tent in the corners, every leaf in the tent is gently dancing.

I think they didn't like much the more frequent waterings of the last 2 days, yesterday i fed them 1 liter per plant and still got a little runoff, that doesn't seem right in a 15 liter pot.

I don't know if anyone has said anything yet. But you need to use smaller pots for coco. I grow in 1 gal pots and it only takes about 2 weeks till I am multi feeding. That is your goal in coco to multi feed to get the benefits of hydro. You are definitely learning a lot with your first grow but I guarantee your second grow will be much better if you follow some of the guidelines in this thread. Good luck brother.
