Help, new to coco

[glued gorilla]

Oh, on that first big dose of Ca Mg, cut your base nutes to half of what you normally use. It will rise EC

[Restorium2]

One thing for sure with a scope, you can tell if the specs are bugs. Or a loop, they work too. 

No guess work. You see them. 

Little plants like that don't need much nutes at all. Most likely too much of something.

Coco is inert, there is no nutrients. A little extra CaMg is needed in most nute lines. He is only giving 1.2 EC(600ppm 500 scale, 840ppm on 700 scale). Either ph is off, locking out, or he needs Ca. When i did coco, i started with 1.0 ec and quickly realized it wasn't enough. 1.3 to as much as 1.5 was my sweet spot for veg. 1.2 should be perfect for these smaller plants, mine came out of the cloner about that size.

You are right about the scope, definitely helps. The ones that you can plug into your tv via HDMI are really sweet!

We still don't know what lighting he is using though. That makes a huge difference on nutrient absorption. Also rather or not this is Co2 augmented or just vented.

When you noticed they weren't getting enough nutes what were the symptoms? Did they look like the pics in this thread?

 

[Restorium2]

Could be they are too wet. Root rot. They need to be able to dry out in a cycle of wet to dry.

No, but that is what they looked like with no CaMg in the program. First sign i saw was yellowing lowers, which was N deficiency

Coco should not be allowed to dry out, just dry back. When it feelslike a well rung sponge, it needs water.

I'm looking at the first pictures and see the stem is actually smaller closer to the coco. Seems to point to a problem in the root zone. Maybe the temp is too high in the root zone.

Thanks you all!  I looked under the lowest leaf and I found black specks so I think it might be russle mites. The strains are gorilla glue, blue dream, green crack, and cannatonic. The temp in the room is around 80F and humidity is 72. My nutrients are advanced nutrients sensi grow for coco part A&B, B-52. I also added revive for the ones with issues. 

 

See if you can bring the temp down to 72 F

Could be, i usually grow from clone and don't see this. I was thinking it was a seedling thing, as i feel i have had this on seeds

72 is pretty cool. I agree 80 with no co2 could be a little warm. Again we don't know his lighting, if he is on LEDs, 80 is good. If he is co2 augmented, 80 is good. Even if he isn't, 80 isn't too hot, just not ideal

How do you adjust the EC and PPM? Also is it safe to use cal mag with revive? I found my PPM a little over 900, how do I lower it. How do you adjust ec and PPM in water before watering? I thank you so much.

[anarowe]

I am trying to get everything I need without spending too much. I am on a fixed income and I am growing for medical purposes. I've been using led two grow bulbs and a small led grow light about 2-3 feet above lights. I am saving to purchase a grow light. I just can't afford to keep buying high price medicine. I can put that money into growing my own. I have a grow tent 60x32x80 with one co2 bag. I have fans in the tent for circulation and a exhaust fan with carbon filter. I looking to purchase a intake fan and filter to bring in clean air but until then I open the tent multiple times throughout the day.

PPM for those little plants should be what your plain water is plus about 400 to be safe while they are sick. 

Check plain water first.

To lower ppm add water.

If you mixed too strong, you can add more water to balance it.

[anarowe]

Okay my PPM before nutes is 150 on the 7 scale, the ec is .23. So I should add nutes until the PPM is 450 and the ec should be 1.2? The ec runoff should be really close to what it is before you water correct. Now should the PPM be the same in and out?

Ppm is just an interpretation of ec essentially. I think you are making this hader than it needs to be. Please pick a measurement to go by, it will simplify. I generally use the 500 scale.  My water is the same as yours. I would say that your total ppm should be 6-700 on that scale total. Add cal mg first, your ppm will be around 400 then add nutes. As suggested, start with half of what you have been doing to account for the CaMg.

I use Botanicare CaMg, max dose is 5ml per gal. Like i said ppm should be around 400 afteradding, but could be a little higher.

Also, you could water with just the CaMg if you are afraid of overdoing. That won't hurt either

[anarowe]

Okay Glued,

So I don't need to do both. So when I am checking runoff should the PPM be close.  For instance If the PPM runoff is 950 I should run plain water because it is too much nutes? 

[anarowe]

That was my next question, thank you

Run off should be close, but usually comes out a bit higher than what you put in. The change in run off is more important than the number itself. If it is rising everytime you water, nute concentration is too high and should be lowered.

With the health of your plants, maybe just watering with CaMg once would be good. 300 ppm is a fair difference from in and out with coco. Soil it would be fine.

[glued gorilla]

If you go just CaMg, give a complete feed when they need it again. At that time just add 2ml per gal to your line up. Ppm will be slightly higher, but they should take it after the slightly low ppm. Just watch run off, it spikes high, a flush followed by a moderate feed may be necessary.

[glued gorilla]

At any point your run off comes out lower than your nute solution, you need to increase ppm.

[anarowe]

I had started using advanced nutrients revive for sick plants, can I use with cal mag?
