Any ideas on this one.

[yummy fur]

This is a bean growing in an eazyplug mini pyramid, it's only 5" square at the bottom 3" square at the top and 5" high. This is being manually watered as an experiment to test out this plug. I am just playing it by ear regards to nutrients, at the moment I give her some 500ppm solution of balanced hydro nutrient, and then a couple of days of water. The pyramid itself cannot be overwatered and the plant is growing pretty well so I'm assuming root structure is good, so I'm thinking if there is a problem is can only be nutrients.

There is a bit of yellowing on some of the new foliage, although it is not getting worse. I am wondering if this looks like nutrient burn, or could it be some sort of deficiency. I'm wondering if I should maybe let her dry out more before watering or should I cut out nutrients for a while.

Maybe ease up a bit, I am seeing some discoloration on your leaf tips indicating the beginning of nute burn. The lighter green in the middle is just your new growth.
What do you mean by "balanced hydro nutrient"? We talking about something like a 20-20-20? Need you to be specific about your nutes. 500ppm should be OK unless you've got a Ph issue. Also EC is a more accurate reading of your overall nutrient levels.

I think she looks good and is ready for some training! Spread her out!

What kind of light are you using, and how close is it? Definitely ease up on nutes. Not by much tho. Maybe plain water between now and the next feed.. that highly depends on what you are feeding tho. Concentration matters.

edit:
I also think you are overwatering.. which could cause this look.. besides the light tips on your top leaves. Which is either light burn or nute burn.

thx for the reply. Turns out this is more tricky than I thought. I want to be clear that this is growing in a small eazyblock pyramid, that is 5 inches square at the bottom and 4 inches tall. It cannot hold too much water by design, so it's more like an inert media although it does contains some soft nutes to start.

It need to be watered fairly often. By balanced nute I meant a 1:1:1: ratio although now she went to flower fast it's more like a 1:1.5:1.5

I fertilise now by dipping the plug into a bucket of nutrient, then I'll water the plug with plain water. Obviously I don't have a clue with this yet and I've been surprised by how quickly she flipped to flower and then stretched. She appears to have stopped growing at about 13" now I'm wondering what the best way to proceed will be. I think under normal circumstances these plugs are meant to be drip fed.

Looks like there would be a good root structure in the plug and pretty easy to flush her out and replace with any type of nute. I'm thinking of maybe upping the K a bit?

Light is 16" from the top about 45k LUX so not too much.

I would toss a coco/perlite mix in the bottom of a 7gal bucket… lay down some mykoz, dust some around the whole cube, then sit this cube in there & bury it with more mix in the pot. Feed as you have been.

@HydroKid239 I fully agree with you straight into a big pot would be good, and it's something I am keeping an eye on with regards to using these pyramids or the larger full size pyramids at a later time because I'm pretty impressed at the root stability.

However I'm not really wanting that at this stage. Right now I'm looking to grow something tiny in the spare space that I have, I thought about a solo cup or tiny pot but that takes too much skill with watering, but this plug takes all the watering skill out of the equation, It's literally a very handy size and easy to move around or place in awkward positions.

I'm not sure how much I should let the plug dry out either, should I wait till just before the plant begins to wilt, or does that put too much stress.

 

[Johiem]

I thought you were suspending it above a rez, I was not expecting... what you do have for a root zone. She is soon to need watering multiple times daily. I would listen to @HydroKid239 and bury her. 7 gal may be on the big side, I'd think a 3 gal would give enough room to finish her out. From the sounds of it you've got an auto flowering strain of some sort. Do you know the genetics?

 

[yummy fur]

That is correct, she air prunes, the plug is completely free standing. The plug is the root zone, the idea is just the normal air prune effect, so the roots eventually fill out the entire volume of the plug. At the end I'll cut it open and have a look.

So what I'm wanting to do is try and grow the best plant I can where the roots are entirely contained with this pyramid mini. Oh yes this is an auto flower, this one is a seedsman purple haze which I've grown as a single stem in another pot and she looked pretty different to this one in the eazyplug. It appears that forcing the root structure has large effect on flowering and structure.

Well in regards to this plant here, what are you wishing to accomplish?
need to know where to put it? You lost me.
You were looking for suggestions. How big is the space you are working with? We’re you trying to ultimately figure out how you are going to finish her out & where?
lets talk about watering it another time. You said the plug took all the watering skill out of the equation. Why change that? The plant looks good. You can easily let the roots air prune & keep this going.

OK let me start from scratch. I usually just grow with my hydro shallow water culture and that's all fine. I'm growing in a walk in wardrobe with a space of about 5 x 2.5 feet. I usually have two plants growing at the most because they get pretty big so when I think there's about 5 weeks to go I'll plant the second one. This is all good.

However I have a lot of freebie beans and other varieties I'd like to grow but don't have the room. I've seen some pretty awesome looking solo cup grows with maybe a half oz of excellent bud. But growing a good quality bud in a solo cup is very difficult, I'm not really looking to the challenge of a solo cup grow, I'm just wanting to grow the best plant I can in a 5 inch square footprint. And it looks like I can do that in this mini plug pyramid.

I do not try and scrog because it's too inflexible and too much work, so because of that, I have a few pockets of spare space where I could just put a saucer with a small plant on it, so I'm thinking why not? I tried a small 5 inch round pot with soil but that was pretty rubbish.

So in a nutshell I want to grow the best plant I can in a 5" pyramid, using manual watering. Oh and I'm using autos as well.

OK I think I got a handle on it, I have a dedicated 9 litre bucket of 900ppm flower nutrient, and I hold the plant by the stem and twirl her around while I use a small jug to pour nutrient into the top and let flow out back into the bucket and I do that a few times per day. Leaves are generally looking better. I think I got a bit caught out by how quickly she flipped.

You sure did!

May as well update this. My original aim was to try and grow a single stem with maybe a 7-10g bud, I did not expect this to grow out this way, I thought she'd just be a small bush but I have her under her own 100W light now which was not part of my original plan, but what can you do. I mixed up a 1700 ppm flowering nute for my big plant, and I've been using this to pour over this one every few hours so the plug is pretty well always wet. Seems to be working ok, no nute burn and leaves have taken on a better looking green. 16" inches so far. Interestingly while the buds are covered in trichomes they appear to be the smallest trichomes I've ever seen!

 

[yummy fur]

Decided to do some defoliating of the lower leaves as there's already enough getting direct light and they were just being shaded.

I like your thought process.
Make due with what you got.

Here's a shot taken in the dark using the iPhone flash it looks a lot better than the normal high contrast light coming straight down. Six weeks from germination tomorrow. Please with the result so far, my original plant is out the window, and my new plan is to keep trying and master this eazyplug until I figure it out, but I'll wait till this is finished.

I discovered a few days ago that the runoff water was 3500ppm! I'm holding it above the flowering res on my big plant now which is 1600ppm and pouring about a litre of nutrient over it 6 times a day, and letting that drain back into the res which has brought the runoff back to the res ppm.

There is a pretty impressive garden of algae growing on the side and with a loupe it looks very interesting. I keep spraying the outside of the pyramid with some H2O2 which doesn't seem to have much effect.

Doesnt even look like the same plant.....Nice Work!
