What's going wrong? 4th run in a row is scr*wed :(

Hmm, cannot find that here in gardening markets.

I can find lime that contains:
81 % CaCO3
10 % MgCO3

here.

Would that work instead of that Biobizz Calmag bottle plus epsom salt (what I'm now using)?

Sounds like my well water....

It will raise the pH. I use K2CO3 for pH up, but did not have to use it with straight well water. Came out in the upper 6s. If used in excess the CO3 builds up in the soil and buffers it for a higher pH. Can be used to your advantage if you watch what you are doing, or overload the soil towards the end.

My current flower grow was raised on well water to try and use the natural Ca/Mg, I also added limestone to the soil initially. I still had to add a lot of my Ca booster and now in flower the soil pH was a bit high in the low 7s. Which is OK for two but not for one.

No,that's dolemite. I have to mail order inputs. It's worth it.

It's Calciumsulfate-Dihydrate right? Maybe I can get it at the local drugstore (where I also got the magnesium sulfate heptahydrate aka epsom salt )

 

[Douglas.Curtis]

I prefer the magnesium sulfate to the heptahydrate. Not exactly sure the diff, but seems to work better all around.

 

[smirnoff420]

Still haven't had time to go buy some gypsum. Is it correct that the idea behind gypsum is that it adds calcium without messing with ph like lime does? Have increased BB calmag dosage to 3ml/L now until I get gypsum.

These ones got 3ml of BB calmag plus 0.5g epsom salt per liter yesterday. The middle one only that because it looks overfed to me. The left/right ones got 3ml calmag 0.5g epsom and 2ml BB grow and 2ml BB bloom.





These ones are due for watering today, will give them the same as the other three.

And this is the single large one:

Those are still nice-looking nugs. Do you think the yellow leaves are caused by lacking calcium?

 

[smirnoff420]

I'm not sure but I think so. Plus that the lower leaves get a lot more light with the vertical stripes than before maybe? I'm afraid to give more nutes, as last time I've tried that the tips started getting burnt. It's a Sensi Seeds Silver haze which needs around 65 days, hope it'll make it.

Hopefully the other 7 ones will turn out better, there is also yellowing starting on the older and lower leaves but not as fast I think.

How are you feeding?

 

[smirnoff420]

The 7 smaller ones around 1/2 to 3/4 Biobizz schedule so far. The last watering yesterday and today more than schedule (2ml/L BB Grow instead of 1ml/L).

The large one only around 1/4 of the schedule because I'm afraid I'll kill it otherwise.

Are you feeding with every watering or every other watering?

 

[smirnoff420]

Every watering as the Biobizz schedule says and as I've always done (I.e before those issues started).

Only now and then when I had the feeling they were too dark green I skipped one watering.

Edit: Skipped nutes, not the water, just to be clear.

What ec are you feeding?

[smirnoff420]

Biobizz is organic, I think with organic its not important (?) Atlesst I've never bothered, don't have a meter.

 

[jackspratt61]

They're looking hungry. Remember to match N to light intensity. With the bump in ca they'll take it.

 

[smirnoff420]

So maybe I should turn the lights down a bit until I've fed them more? Since I just watered them I cannot give them more right now.
