1st timer grower in UK

Yea coco perlite 70/30 mix.
1ml cal mag 1ml of micro, grow and bloom.
They have been fed twice since we got them last Friday. They were sprayed with a neem oil mix 2 days ago.
PPM not measured.
Ph going in a 6, was coming out higher, but it's new coco
Put the plant in the shower and rinse the lot - something is very wrong so what have you got to lose

@Bill284 - we are all Litres over here
 
Coco must be kept moist at all times.
Feed nutrients every day to run off at 5.8 ph exactly.
Never any plain water never letting it dry at all.
Do you add calmag first and mix it well, before adding nutrients?
Your measurements 1- ml per litre or gallon?
What's room temp and rh?
Clones like a slightly moist environment at first, not too hot either.


Stay safe

Yes cal mag first before anything else.
1ml per litre.
Room temp is 24 degrees and rh is 69%
Could this be nute burn, am i giving to much nutes?

I should have read the title first. :thumb:
Morning Roy.:ciao:

Will that not screw up even more? My ph of tap water is over 8ph
No, remember pH is purely for 'ideal' nutrient availability, nothing to do with the plant
Rinse it, then feed as normal according to the bottle - are you using BioB?
If so, 1ml/L is nowhere near enough, you should be on 2-3 ml/L by now

Using the below, also showing the amounts. I was told to do 1ml of all cos they still seedlings

But they're not seedlings are they - clones?
 
Ok. So still flush them? Then fed. Or if I feed at the right amounts, will they get better?
Personally, I'd probably rinse the neem oil off the plant and clean the root zone for a fresh start
You will see new growth within a few days, then cut out all the dead leaves

Can you explain the best way to clean the neem oil off and how to clean the root zone please

If you diluted neem with soap, just a shower will rinse it off, mostly
Just run 3L of water through the soil - plenty of run-off
Some folks add CaMg and pH it, I just chuck it in the shower
My plants get a rinse end of veg and another 6 weeks into flower and they love it

And 3 litres will be enough to clean everything, I'm using 5 litre pots

Should be, you just want a bit of run-off - I also sometimes run 1L of 1% H2O2 through it too to re-oxygenate the pot, but that's getting into nerd territory! :cool:

Ok, I'll put the plants in the shower 1 by 1. When should I give them nutrients? Anything else I can do to stop this happening. 2nd lot of plants in a month that have gone like this.

Nutes day after, when it's fully drained but not dry
If this is happening repeatedly, check your pH and feed rates carefully - it shouldn't be happening
Check/calibrate your pH meter and go for pH 5.8-6.2 as per bottle

I'll recalibrate my ph pen just in case.
But been feeding at 6. They have only had 2 feeds since I got them a week ago. Should I be feeding more?
