Help my plaants

[Growerin]

Hello Growmiees ,

I use BioBizz as a fertilizer. The temperatures fluctuate between 19°C and 25°C.
The humidity fluctuates between 50% and 70%.
The pH value thing is a bit strange for me. First I had a pH value of 7, then I used the pH-Down from BioBizz and tried to get the value down to 6-6.3. Now the pH value at the bottom of the pot is 4.5 pH and 6.8 pH at the top. How can I distribute the pH value evenly?
Is the EC value important? I don't have a measuring device for this yet.

What does my plant have I don't understand it anymore? I have now ordered CalMag from BioBizz and potassium from Canna fertilizer.
What do you think?

XOXO from Germany

It looks to me, like a ph or nute lock issue. What are you growing in? If it’s a commercial bag type soil, unless it’s peat or coco base, I’d simply ph my nutes to about 6.2 and water with that, don’t chase runoff, or soil ph. First thing I’d do is flush the media very well and start with a new watering/fertilizing regime, just ph your input water/nutes to about 6.2. If it’s a coco or peat base soil, I’ll defer to others. EC isn’t nearly as important in soil as in coco/hydto.

You could add some lime before you plant

I think the 19°C is too low for nights temps. How is the ground temp? From the pics i see a tent(on the floor), my quess is that the room is a little to cold.

Your pH has dropped very low from too much fertilizer and not enough buffer. What kind of water are you using to start with? The only time one should add acid or pH down is if the tap water has a high EC. If you get an EC or TDS meter you will know what you have at any given moment. Both meters are very important when trouble shooting.

Yup low ph locking out magnesium. It will appear to be a magnesium deficiency when in fact the mag simply will not be absorbed when ph drops too low. So please do not add cal mag it will only make things worse. I would try a flush with regular tap water first. Go from there.

Temp issue and lockout as above posters have said flush it all and start from fresh slowly and remember its not the more the merrier in this case so to speak less is more for a good start off point hope you get it sorted just shout theres always someone to hand ..

I have got this soil for my plants. How could I add lime to it?

The 2 little ones are Amnesia and the big one is AK47. The type of soil is from BioBizz the Light Mix. Okay I will flush them with pH-6,2. Thank you so much

The fluctuation of the Temp is not good for the plant right?

ph value of the tap water is 7. Should I drop it to 6,2?

I use tap water. Ok I will buy an EC-meter and will give you information about the measurement

The temp is now 26°C. What are you using when the temp is too low. Should I buy a heater?

You just mix a bit with it before you plant. I do it in a wheelbarrow. A tbsp or 2 per gallon is what i do but I use promix diluted with perlite to make it loose.

26 should be ok. Just a cold room with cold floor can cause problems and i saw one that looked like your 2. and 4. pic but all over the plants. But that was in a cellar and raising the pots with isolated boards did the trick.
I don't think that you have to do that. 19°C is imo on the low end whats working so when you can raise the temp a bit it should be ok.

Biobizz light is a peat based soil, I don't use it, but it's treated a little differently than a regular soil. Hopefully someone can give you advice specific to Biobizz light.

 

[MedScientist]

Could you post a pic of the full plant? It will help to get a clearer idea of what's going on.

Biobiz light says ph 6.2 - 6.3. Temps don't look to be a problem to me.

I am leaning towards Overwatering, which does not always mean too wet soil, but could be caused by the higher humidity. If you Google "Overwatering", you will see all the leaf symptoms, which can occur.

And compare to yours.

You will always have temp fluctation ie night temp day temp light on light off its good picture yourself sitting in the sun all day you will want to cool down after to much sun

When temps drop, I add more light wattage, and the light's heat keeps the garden warmer.

oh yea? why would you not add ph down, if i may ask?
