What's going on with my wedding cheesecake?

[Offmymeds]

Day 35 - She's been topped and LST going on but at only 5" she is a squat little kumquat compared to the others I've seen. As you can see she's nice & green, & still very pliable. She getting a lot photons. She's in a 5 gallon pot with 50/50 spaghnum peat moss & vermiculite w/ 27g dolomitic lime & 10g gypsum. The pH runoff is coming out at 4.0 when 7.0 goes in.

Might have yourself a runt

 

[puffdatchronic]

4 ph coming out is bad. Id say you are locked out of something.

Could also just be that this plant did not like to be topped

 

[Offmymeds]

No choice but to let her grow to see what happens. I'm going to bump up the pH on the next feed from 7.0 to 7.5.

 

[puffdatchronic]

Yeh see what happens.

The thing is soil acts as a ph buffer ,meaning it will balance out the ph close to the soils original value anyway,so you shouldnt be worrying about phing anything.

Its of utmost importance with soil to go with a known cannabis brand or if not check the ph of the brand you are using, it will be on the bag. Some peat based ones are 3ph or so. Ive been burned once before by the same issue. My plant just died a horrible death on that occasion

If you’re offsetting the feed you’ll need to go much higher than 7.5..

What are you pHing anyway? Feed? Plain water?

If using plain water what is the pH of the water?

You’re probably doing more harm than good if you’re lowering the pH to begin with.

I'm raising the pH, it was low originally because this is the first time using peat moss for me. I'm pH'ing the feed.

Yesterday I just tested the runoff for another plant in the same soil and the same nutes going in that soil at 7.0 came out at 6.0, much better than the 4.0 runoff coming out of the auto. It will be feeding her again tomorrow with lots of runoff. I'm hoping I just needed to give the lime a little more time to kick in. The plant looks very grean and healthy other than being shorter than any wedding cheesecake that I have seen online at this stage.

What light are you using and how far?

 

[Offmymeds]

I built GreenGene's ultimate DIY build. It's at 24" with about 33,000 lux

is it pure peat or got feed in it? No need to feed until 3 weekish. Looks like the soil is too hot that’s why the pH has crashed.

Give it water and root stimulant until first set of leaves on the bottom fade yellow. Start at 1/4 strength and go from there

Some autos don’t like topping ... it severely slows or even stunts some strains .... LST alone would have been enough to shape an auto .

 

[Budzbuddha]

Medium is playing into issues - peat runs acidic from low 4’s to about 5.5 ( + or - ) .

Next time try a 50/50 blend with bagged ammended. Vermiculite holds moisture - especially at root level. Dolomite addition probably not properly ratioed to mix , gypsum same thing.

That plant could be more trouble free with a good bagged soil instead and on water ph before use.
That mix you are using sounds nute and ph unstable because of majority of peat.

IMO go get a good bagged mux ... FFOF / Kelloggs / Dr Earth / EB Stone - whatever . Prep a larger container with it then transplant that plant into new mix - water it appropriately ( not runoff ) and leave it alone.

Pure peat. No feed in it. No PH value on the package either but I understand peat is normally around 4. I just left a msg with the mfg co asking the value.

The runoff is coming up but still below 5. She seems to be pretty happy & looks as though it's time to flower.


Wedding Cheesecake day 39

 

[Offmymeds]

Update - She's doing OK. 14 days later she is 22" on day 54 with supposedly 16 to go. She needs to fatten up a lot in 16 days.

 

[puffdatchronic]

Looks like she was just stunted for a while with the topping.. it can happen..looks good now

Does this occur regardless of the container size?

what happens in 16 days?

You’re way more than 16 days out. The breeder info is almost always lies to get you to buy it based on it being a “fast finisher”. I have an auto that said 53 days from seed, it’s “day 40” with flowers smaller than yours. Just treat it like you would a photo, let it tell you it’s ready.

I always add 10 days to the described time. Just waiting for it to get ripe.

I moved it away from the good white lights bc I had to flip that space & need her to get more than 12 hrs/day. I hope it adjusts to the light well. It's an old California Works SolarStorm 220.

 

[Offmymeds]

I haven't bothered to test the runoff, just feeding her without adjusting the pH that falls naturally at 6.1.

She seems to be OK with that. Filling up fast now.

Probably should have put a few stakes in for those lower branches.
