and thats one thing you gotta be thinking about being that u dont have the soil elevated in a fabric pot, the air flow just isnt there now, so more chances of the soil staying wet and going anarobic in spots creating the conditions for Fusarium and other baddies to thrive...
i already had a couple extra fittings but i cant find them.Its really a good idea to buy a handful of extra pieces for everything in your drip setup. That way your watering system isn't relying on a 2 dollar part on the mail.
Cant say I've never broke a drip piece here and there. I'd imagine yours is buried under a bunch of shit he was told to whack. Not saying your help couldn't be more careful, but that's a pretty small problem imo.
Honestly you've had 3 years to vet a good helper, and with that many plants you don't even really need help till fall eh? Just observations from what you've shared and posted.
thats what backyardfarmer said too. he said there's too much Mg , and i should foliar albion or JHB calcium.. he also recommended cobalt and zinc sulfates, not sure how much though. and phosphorous too i believe...Sure looks like a calcium deficiency to me!
