Had to to color correct from that Blurple ….
Plant seems pretty uniform and not seeing systemic issues. Not sure why you blended 3 different mixes.
Fox FarmOcean as Base ( bottom 1/3 ) with HF as top fill would have been sufficient.
Top dressing FFOF is fine to ” recharge “ host medium - against medium becoming exhausted from plant.
I would add EWC to top dress to help supplement the microbial life / breakdown of dressing so plant gets nute uptake.
EWC is a given for
all bagged soils . IMO.
FFOF can also be made into tea / soil drench by simply bubbling a cheesecloth bag in a bucket with air stone.
‘Plant is already accustomed to soil / feed from this and is listed on back of bag.
FFOF is pretty nute dense so a tea is easy to do. Also , can the CO2 - it is worthless in a tent with extraction fans going.
