Cannabis as houseplant

[Mr.furley]

MDR The cutting that drastic is just to reform the plants shape after getting to bushy in the wrong places, My Bad. Most times the plants get trimmed about once a month, this happened tonight to that plant and thought I'd share with you,

This help slow the plant "down" for a minute which helps decrease the need for nutrients, water uptake and photosynthesis, At a point you must either feed it more or cut it back.

 

[MDR]

Thanks for sharing. I'll post more pics today or tomorrow to show my progress.

Update

The smaller plants look healthy.

The larger plants I'm a little worried about. I'm still getting yellowing, but not sure if that's due to the aftershock of flushing. The one on the right is absorbing water faster as you can see the surface dirt is dryer. I'm thinking of waiting another day or two before watering again. Should I water with nutrients again or just plain pH?

 

[Mr.furley]

What is your going in PH and ppm's the last feeding and date? And how have you been feeding?

Are you giving a General feeding to all of your plants or are you giving them specific to what they might need?

When you're having yellowing leaves there is a couple things that need to be checked off the list of what is it?
1) proper Ph.
2) proper nutrition levels.
3) to much/not enough light.

We have covered PH with a flush, it looks like nitrogen deficiency but you are sporting "tip burn" around the plant so I wouldn't put it past boron, manganese, and/or zinc, a trace mineral. Personal I'd lean to Manganese due to the fact that your PH has been high and it is absorb at 5.8 and below.

So next is it happening close to or far away from the light?

 

[MDR]

What is your going in PH and ppm's the last feeding and date?
- 6.2pH
- approx 350 ppm
- Nov 21

And how have you been feeding?
- Dyna Gro Grow (1/4 tsp per gallon)
- watering can to top of the coo coo coir

Are you giving a General feeding to all of your plants or are you giving them specific to what they might need?
- they've been getting a general feeding

Is it happening close to or far away from the light?
- the tall plants are about 6 inches from the light

 

[Mr.furley]

By what I'm read and the look of the plant.
I would get the PH down to 5.8 and up the PPM'S to 500, remember you can alternate water, feeding, water, feeding.
Is the yellowing leafs only happening by the light?

 

[Mr.furley]

How about that calmag?

 

[Canuck147]

To me - looks like they want/need more light. But only if you want a bush.

 

[MDR]

the yellow leaves always happen to the lowest fan leaf and then work it's way up.
I used the proper does of calmag in the last feeding.

How would I up the ppm?

 

[MDR]

I figured it might be easier for me to do this. Tell me what kind of dosage I should be mixing. I have a feeling I'm being too conservative.

Soil: Coo Coo Coir & Perlite mix (3:1)

Dyna Grow (7-9-5) - I mixed 1/4 tsp per gallon of water

CM Plus (3-0-0) - I mixed 1ml per litre of water

 

[Mr.furley]

1/4 tsp= 300ppm
1/2 tsp=500 ppm

 

[MDR]

Thanks, I'm mixing a new solution.

I also learned that the cal-mag has to be mixed prior to the regular nutes, which i didn't do properly before.

 

[Mr.furley]

It would be best to also start mixing to the plants just specific needs.
If your going to use PPM'S as your base for nutrient needs you can adjust the dosage amount up and down and should be monitoring Ppm's in and out each watering.
Most cannabis grows for production though vegetation around 800 to 1000 ppms and flowering 1000 to 1200ppms, so you are at a low end of the ppm range for your plants. The nutrients Bottle says "maintenance" meaning bare minimum don't be afraid to go higher if needed. Your ppm's before the flush borderline acceptable before the flush at 1000, that is probably the tip burn but the plant was getting the balance of what it needed across the nutrient range with the PH out of whack.
Just for full disclosure, I don't use PPM'S on a regular basis. I found it to time consuming I just look at the plant now a days.

Mix Your Nute is this order:
SI
Calmag
Potassium base (veg/bloom)
Nitrogen base (grow)
Micro nutrient/bloom enhancers
PH up or down. Never the two in the same gallon.

Keep a eye on your light. It's your next question.

 

[MDR]

I made a new solution (1 gallon)
pH = 5.5
ppm = 680

4ml of cal mag
1/2 tsp brought me to 500 as you mentioned, so I added another 1/2 tsp which brought me to 680ppm.

I used pH down to get me to 5.5

 

[Mr.furley]

That looks good and should get you back on track. Your Leaf that has started taking a hit wouldn't come back so focus your efforts at New growth.

 

[Mr.furley]

Also try and get that pH in and out stable around 6.0
Swing a little up or down when needed.

 

[MDR]

Update: The new growth seems to be doing well. The smaller plants that I topped weeks ago are start to grow upwards now with bigger leaves.

I probably won't need to water for another couple days
Should I use the Cal-Mag and Dyna nutes for that watering, or just pH adjusted plain water? I know you're supposed to rotate, but I just finally got my ppm back up to 650-700.

 

[Canuck147]

Go with the nutes.

 

[D.A.A.S.69]

What 147, said.

 

[MDR]

will do
