When did you last fertilize? And what kind of soil did you use?

I repotted late may or early june with approx 1/4miracle gro potting soil 1/4 miracle gro cactus/citrus soil and 1/2 promix ”high porosity” myccorhizae. I sprinkled just a bit miracle gro vegitable mid june but found espoma berry tone which atleast has some calcium and mg with 4-3-4. I applied that fertizier end of july. I looked everywere for chelated iron to fix ”chlorosis” and something liquid, purchased and applied smallish amount of “marphyl soil enhancer.” link below https://www.amazon.ca/gp/product/B073DKK4XS/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&th=1. Trying to get some quick nutrients. I’m trying not to over water/underwater but it’s been hot and dry in Ontario. Maybe its just root damage when i repotted? canada has no good Citrus fertilizers.

 I won't say anything   about something I know nothing about

Citrus fertilizer - Amazon.com or drop ship to your closest cross-border Box Store.

Potting - FoxFarm or Pro-Mix Premium.

Amendments - biochar and worm castings

Foliar Spray - Southern AG and GrowScripts Calcium + Bloom formula

Move the plant to a sunnier location. Wind and wet cool nights can spread fungus. Before adding iron I would try flushing the pot for ten minutes to remove any excess total dissolved solids. Too much fertilizer shifts the EC out of range and the water and nutrient uptake suffers.

 I would change the soil in the pot and wash the pot with straight bleach to kill any fungus before putting In  fresh soil regardless of the type whether it soiless  type or natural soil in this case it needs to be changed and many on here might just agree with me here they are experts I'm not

Just use an over all great fertilizer and the right mix with lots of sunlight and your trees will thrive)

No fixing this or that. No dealing with products that will treat one thing and that will lead to another problem..
