Not sure what I did to my coco test

Glad to help. Keep up good ventilation on them especially when misting. They are in big pots for their size, keep in mind that it is possible to be too wet in coco when the roots aren't established, or when they are growing slowly, or if they are sick. Ventilation is pretty important.

I agree with Wrrrl. Looks like a Ca or Mg issue. Typically feeding that young with a base needs cal/mag supplemented, especially if you are using RO. . I always supplement with Calimagic at early and taper off as I increase my base to full strength.

Also Your Ph at 5.6 is lower than I ever take mine for what it's worth and if you are getting large fluctuations could be causing issues. I don't normally see leaf twist from a deficiency.

Right on. I added an extra 200 ppm of calmag. I have calimagic as well. That puts the res at 550 all day.

I've never seen leaf twist in a deficiency either. I finally got pH to settle at 6.2 with this res. It stays pretty much static since it's a dtw res. Been 2 days at 550 and 6.1ish or 6.2.

I'll see if the pH and calcium helped it in a few days but they were certainly reaching for the lights at 6 pm today so lights are most definitely going to be my hold up until tomorrow.

The wife and friends are about halfway through the trim today so the room will be free for these to get the mh sometime tomorrow or Tuesday. And no I use tap not ro anymore. It sits at about 100-150 about 65 or so is calcium

Just a bit of basic coco advice based on what ive read here:
5.8-6.0 is best ph range for coco and the plant roots love a good wet-dry cycle, its perfectly fine and well accepted to let coco dry between watering, not 100% dry out mind you, but a general rule is to stick a finger 2 knuckles deep, if you feel moistness give it another day before watering, if it feels dry its time to water, depending on where your plant is at in its life cycle the coco will be "2knuckle dry" every 1-3 days. at mid-late flower stages you can try watering multiple times a day but honestly my coco coir/cruton/perlite mix holds enough moisture that i have never needed to, i did notice small increase in overall weight when i did it despite the fact that it was unnecessary but found it wasnt enough weight to balance the cost of the nutrient waste, if you stick with drip-to-waste coco then when you dial in your setup you should only have roughly 15% runoff watering once daily during flower, your plants will be recieving and usuing nutrient regularly with an ideal ppm, and you wont be wasting nutrients which= saving $$

also i cant really see your pics cuz they're frozen/taking ages to load (next time try using a third party site like photobucket to post pics) from what i can see though it looks like youre doing an open grow.. should look into investing in a nice tent with some better lighting and ventilation, your plants will thank you :)

These two are just side projects as I've mentioned before I'm middle of harvest iny main room. I have a 4 by 8 tent a 5 by 5 tent and a 4x4 tent. My environment is not the issue.

I'm aware of how to water the plant. Yes I'm wasting some nutrients with my high runoff percentage but honestly it's megacrop at 400 ppm who cares it was like 12 grams of it. As farasthe watering cycle it's fine too they are growing vigorously (albeit one with rusty spot) and not showing any signs of over watering.

I've also certainly got appropriate lighting with 1600 watts of hid available and cmh on the way for the next room flip. Again this cfl are only biding the plants time until tomorrow like
I wrote in the previous post.

The only reason this thread is in the newbie section is because no one uses or is active in the sick plant forum. That and I consider coco to be soil less hydro and there arent many on this site and especially not in the hydroponics section.

So I dunno I guess the Cal mag helped some. I'll give it a few more days then I think a good washing out with pH'd water and then up the EC a bit and I'm good to go.

It's good enough at least. I'll stick em in the room under mh sometime this week or early weekend. Then I'll give em to the mil in a couple weeks.

This is seriously about as easy as it gets so far. I just mixed the stuff up rigged up a sort of legit drip ring thing on 1gph emmiters and done.

So far I feed 15 mins 3 times a day and they are doing 20/4. pH is about 6.1-6.2 and ppm still about 500

I guess this will be the last I update this unless something wrong happens.

Every 3 days? This isn't dirt. This is coco. If I let it go 3 days without watering it would be dust. And I've seen multiple sources recommending not to ever dry out your coco or it gains hydrophobic properties. Also I've read that to gain the most from using coco multiple daily waterings is ideal. Similar to an ebb and flow system of which I have lots of experience
Bro, you are on point. They just needed Mg if using tap and Ca if ro.

You are correct never dry Coco it will salt fux you after 3weeks with 2k+ ppm run off using plain water, also about treating it like flood tables.

With real life sheet going on who has time to baby the plant's, I'm lucky to even get to the room every day or two as well.

Coco binds the magnesium in the fibers and don't release it. It's mandatory to add mg or camg every time or get rusty sheet all day.

Good luck. :-)
