Feedback for my soil mix

Hi guys,

I'm about to make my next soil mix for four 20 litre pots of Northern Lights in a scrog. I've put a recipe together, but I'm wanting to create a stable Ph and Terra Pro has lime in. Please can the forum give me their thoughts on this ?

My recipe is:

50 litres Canna Terra Professional (62.5%)
20 litres Perlite (25%)
10 litres Worm castings (12.5%)
800ml Ecothrive Charge
1 tbsp / gallon Seaweed meal
1 tsp / gallon Garden lime containing magnesium and calcium

Any advice or thoughts would be much appreciated!!

Cheers.

Peace out.

Your mix 2/3

Alfalfa Meal 5lbs 1cup
Crab Meal 5lbs 1cup

Kelp Meal 5lbs 1cup
Langbeinite 5lbs 1/2cup
OysterShell 6lbs 1/2cup
Neem meal 3lbs 1cup

Water from begining to harvest

Cheers for that swedsteven. Would certainly make watering easier. Do you think the Ph should be ok with organics (compost teas and AN feeds)?

The medium buffer the ph . No need nutrient if u put amendements in your medium .just water as long as it soft water my tap is 120ppm .

Compost tea with molasses is very good to activate ur soil army of microbes and fungus

I live in UK, and struggle to buy some things on your mix. I'll take a good look though. Cheers !
