3 things ...
1. Next time ph your water / and or “ feeds “ . FFOF is prebuffered at 6.3 ( right out of bag ) , even if you are “ trying to grow organic “ ,
you should
at a minimum try to
MATCH the host medium. Look at your leaf and the following... Ph swing
View attachment 4574493 ..... look familiar ?
2. You are overloading a medium that
is already adequately charged ... by dumping excess into it . EWC is a fine addition to “ any soil “ .... CALMAG can be a necessary evil at times ( especially led grows ) when symptoms call for it. And that can be caused by lower transpiration in led grows compared to HID / HPS that provide IR and heat .
3. Believe it or not , that soil ALONE on PH water would have squashed much of those issues .
Also , that bottled feed would be surpassed by simply “ top dressing “ more FFOF ( alone ) and just watering in.
Think about it .... plant begins life in host medium ... it becomes acclimated to it ( without excess outside Nutes ) , you top dress MORE when necessary ..... plant is not overwhelmed
because it’s the same host soil. All you are doing is recharging it as it is depleted during grow.
How simple is that ?
Many growers trip themselves up with this soil and its for the same reasons that you have going on.
