Root rot or deficiencies?

[khirmun]

Hey.
I am growing these clones of Farm Cheese by Berney's in Coco/perlite mix, hempy style (except 3 of these have no reservoir and just plain holes in the bottom). I was using organic teas/aquarium water pH-ed to 5.8-6. Organic teas were of fishmeal/bone meal aerated for 2 weeks.
I would give them nutes diluted with 1/10th of water every 4th day and just plain water everyday. They are looking like this. The clones are 15 days old.
The light is DIY led consisting of
2 x CREE CXA 2530 at 23W each
3 x plant spectrum LED cobs at 50W each
60 x 3W 10,000K leds at 138W all.
So that's a total of 334W actual wattage draw.
Does this look like some kind of deficiency or is it root rot?

Tea's and aquarium water look to be making some very thick, heavy mud through accumulation of small particles on the surface. Could be that "just watered" look I suppose.

What does 1/10 diluted nutes mean? The tea/aquarium water/meal mixture or something from a bottle? If so, what?

"Plain water everyday" means you're watering every day?

"No reservoir/Holes at the bottom" means you punched holes at the recommended height for hempy but filled completely, or that you punched holes at the bottom/edge of the pot?

Temp/RH? Day/night differential?


And most importantly, have you tried this successfully before? Are you following someone else's work?

I think you may be watering a little too often for how young your plants are and thus they are not getting feed enough.

Are you PH'ing your plain water too?

Do you know what the PPM or EC of the nutrient solution that you are feeding is?

 

[khirmun]

No idea about ppm/ec of water.
I do ph my plain water.
The holes are in the bottom of 5 pots (no reservoir so I water every day), 3 have hempy style reservoir. By nute I meant the teas I use, so 1part of the tea I am brewing and 9 parts of plain water.
Tea has 1 tbp fishmeal, 1 tbp bone meal in 1.25 liter, aerated 2 weeks minimum.

 

[Mikell]

Like Ganoderma said, they're far too small to be watered that often.

I think your feed regime is suited for soil. Growing in coco is hydroponics, the nutrient profile needs to be fairly specific.

I would head to the coir forum and read as much as you can of the stickied and 5 star threads. If you can, source a two part base nutrient intended for or used for coir.

 

[khirmun]

I can't source the two parts nutrient. That is the basic problem.
I live in a 3rd world country where if you can get your hands on some soluble nutes that seems like a miracle. It took me a week to find perlite and even that was in another city. So I dont know how to go on anymore. My soil grow failed miserably because I think the soil mix compacted/went anearobic/stayed too wet and killed my 2-3 months old plants.

 

[Mikell]

Hmm.

Too costly to order? MaxiBloom, JR Peters, etc come in 1lb bags.

What was in the soil mix? What do you have available?

Soil seems like the way to go, it is much more forgiving.

 

[khirmun]

I know soil is forgiving thats why I went towards soil.
I tried soil with 33% topsoil, 33% peat, 1 tbsp Fishmeal, 10% cow manure well rotted. Worked for 4 weeks. started compacting.
I tried top soil with perlite, coco coir, fishmeal 5% cow manure. Worked for like 2 weeks. Compacted. 7 days interval between watering and still stayed wet. Root rot.

 

[Mikell]

What percent perlite?

Dude, you overwater so hard. Let them be untill you feel that the pots get light. Don't let the coco dry out completely, but those small pots should take like ~3-4days with no feed and big pots... maybe two weeks.. they are way too big for such small plants.

And coco is no soil.. Don't ever feed plain water. If you want to flush them then use 50% nutes.

If you get the pots 100% full of roots then you can hit the valves and feed them like you are feeding now. Keeping them wet all the time. But for now let them breath. Overwatering is the nr1 plant killer
