Something is wrong??

[R3za92]

Nothing has been added except dolomite lime in liquid form and Epsom salts to the larger plants.
Water only with the small plants.
As said the small plants are in 3 different soils one osmocote with 30% perlite one a searls mix with perlite and the other Dr Greenthumb's.
Dr Greenthumb's would be lucky to have 5% perlite and I added to take it up to 30%
Plants grow In straight perlite so porosity is not a problem!!

Dolomite even in liquid form will take weeks if not longer to effect anything other than ph. If it’s calcium it likely won’t have any effect for months. Try using an available calcium source like calcium nitrate and either foliar feed it (preferable) or water it in

It's not a living soil in 5 of the 8 small plants. Over watering is usually the root of almost all problems in soil and the plants are not over watered.
Even the living soil plants are showing the exact same problems as the others.
I would think the 3 living soil plants that have just had water should look fine at 3 weeks of age.

I’m still leaning towards a water or ph issue causing nutrient lockout in the rootzone specifically calcium.

It'd 25% calcium mate and it is designed for both pH up and correction of calcium problems.

That still doesn't explain why the small plants which are showing the exact same problems look the way they do!!

But it’s a slowwww release source of both mag and calcium. Like over months not weeks and it’s a poor source calcium. Calcium is the hardest nutrient to uptake via the rootzone with calcium carbonate being one of the worst. Switch to a more available source of calcium.

It can also lead to ph issues not fix them

 

[R3za92]

You’ve also added 2 magnesium sources. With the Epsom salts being pretty harsh on soil and being a sulfate will lower ph while raising salinity. Epsom works better as a foliar treatment but at this stage I’d say your issue isn’t mag related.

I’d say it’s all the soils having a low Availabe calcium level combined with low root zone temps and probably a water issue thrown in the top it off.

Personally I don’t think you have 1 issue you have a few which are compounding and presenting as 1 issue.

I've used both of these on the larger plants and nothing has changed!!
Still why are the small plants showing the same problems at week 3 as the others have shown.
The small plants should look fine as the 3 soils would easily have enough nuts to support them at this stage of their life.

 

[Porky]

If I only had one source of medium I could understand what your saying Rez but I'm running 3 totally different soils and all are showing the exact same problem.
I also agree it's more that just one deficiency but to have the exact same problems with 3 different mediums is what's got me fucked.

Have u been leaching your town water Porky?
I know in this huge crappy weather time the water authorities are adding heaps of additives to address the dirty water.
Have been getting town water lately as my well is contaminated.
I've noticed so much chlorine etc town water is off colour and reeks of chlorine.

No I haven't been but I did catch a lot of rain water and was watering with that about 4 to 5 weeks ago and the plants showed no difference.
I've tested ph 3 times and it's been steady between 6.8 and 7 from the tap.

Everything has been added at half strength I might add as I didn't want to over load the medium.

Nice info there... I would summarise the issues personally... If I were to look at those plants at a glance, I'd say the soil that the super deficient plants are growing in is really shit and it's probably very cold. The not so shit plants, I'd happily nurse them into health.

Cold is not a problem as the lowest I've let it get is 23c but I kept them at 28c for 3 weeks and nothing changed!

You been feeding those via the rootzone? Try the cal max via foliar. Guessing that has some boron in it as well or nah?

Could also be the one thing they all have in common still, the water. You had a lot of rain recently? Rain can change the mineral composition in local waters sources.

Is that temp in the tent? What about down at the roots?

Yeah mate thermometer sits on the floor.
Temps should not be a problem!!
The tent sits on rubber mats too so the floor is nice and warm all the time!

 

[frankreynolds]

What about leaf surface temp? If water isn't moving through he plant through transpiration Calcium won't move through the plant either. Adding more won't fix the issue

This is just weed Frank!! I've grown under far worse conditions that what I have setup currently.
What's got me fucked is that 3 different mediums are all showing the same problems.
Temps are good for growing I can guarantee that!!

 

[frankreynolds]

it's jsut weed? then why ain't it growing? the stuff grows through cracks in concrete.

 

[Billygoat]

maybe ya plants have got long covid?

you wanna just send me the cash now mate?
