Need some help/advice

[DillyDally]

So I've had a good first run on a couple of harvests (I am a newbie), But my current plant is starting to look a little unhealthy i was wondering if anyone could give me some ideas on what to do ?

My soil mix is 60% Coco + Perlite with 40% being home compost and some minor amendments like small amounts of Rock Dust, Alfalfa meal, Malted barley + 3 handfuls of some worm castings.
Watering maybe every 2-4 days in a 3gallon / 11 Litre pot. Tent is constantly around 1.15Kpa / 23c and 60% humidity

Bottom leaves are turning yellow fast and the new growth is dark green but with yellow edging.

Is it hungry ? idk what's going on.

Yep looks like a deficiency of some sorts, make sure the ph isn't too high or low because it will lock out some macro/micro nutrients

What have you been feeding it ?
If nutrients what strength ? & PH before feeding?
If nutrients Do you flush or allow some to run to waste ?



I reckon it needs a good flush with feed at 5.8 or 6.0. You could flush with a lower PH to try balancing things ,either way you’ll probably need many litres to flush out the old crap that has built up,, the shitty colouring on your leaves is because the PH is to high, locking out other nutrients that it needs and are only accessible at a lower PH.

I have not been feeding it, just eating whatever is in the compost / worm castings

So i should buy some ph down for the water, reading up my area maintains a tap water Ph of 8
I did buy some A/B nutes today do i PH the water down first before adding the nutes ?

Add nutes, then adjust pH. They will lower pH by themselves, then add more pH down if needed
