Hello Chef. I did the whole trade school food service program, Apprenticeship program 1 term Lambton College and 3 Kensington Campus George Brown College in Toronto back in the very early 80s. Decided it was not for me and I got out of the business in about 90. Spent 30 years driving big rig west and north of Edmonton. AB. BC. YK and Alaska. Even did a few ice roads way back in the good old days when ever they where.
After reading your post and looking your plant over. I'd say try not to use worm castings with Ocean Forest. If your not super careful watering.
Castings in a non living soil potting mixes can create mold problems you really don't want to deal with. You are far better off to keep it in the family with Fox Farms products.
I'd say that the 4-4-4 will get your plant buy if you transplant in the next week or so. Be very careful with Ocean Forest! It's super hot.
I'd fill the pot 2/3 with Ocean forest. Mix enough to finish flling the pot. 50/50 peat moss based potting mix and Ocean forest.
Plant the seedling in the top 1/3 of toned down mix so as not to have it sitting in real hot soil. You can just water with straight water for 3 weeks
after transplanting.
If you would like to help your medium.
1 Gallon Ocean forest potting mix
Add 40 grams of garden lime pr gallon of potting mix. Peat is quite acid. Helps bring the ph up - Adds Magnesium and Calcium.
Add 10 grams of Gypsum pellets pr gallon of soil. Adds Calcium and Sulfur.
1/4 cup Rice Hulls is silica.
Hand mix very well befor filling pots
If you don't use rice hulls. Add any silica (liquid) amendment to your feeding skedual.
If you look closely at your sick plant.
The brown blotching on the leaves is conducent with calcium deficiency.
There is also inter vainel stripping in the leaves. Magnesium deficiency.
Plant quite yellow, I'd say that your ocian forest ran out of food (Nitrogen) for your plant some time ago,
and your plant also requires a little
cal-mag in your watering solution. Maybe a double shot first time.
As directed after that.
Transplant asap, Water with
cal-mag in your feeding solution as directed.
Start feeding
Fox Farm nutrients about 3 weeks after transplanting and your in great shape.
