@sh4rk_b0y, thanks. It’s in coco loco soil. Canna A-B 1 teaspoon per gallon last few feedings. 1 teaspoon per gallon cal mag. 1/2 teaspoon recharge. And been using R/O water but not ph ing the water
Too much Cal/Mag. 1 ml per liter. Its already got N in it.
I would flush her ASAP with 1 ml per liter of A&B 0.5 ml per liter cal mag. PH it to 5.8 flush the crap out of her with plenty of runoff.
The Plant can't uptake water right now because the Ec of your Coco is through the roof and fuck knows what your PH is.
You need a PH pen Bro.
Once you get A&B above 1 ml per liter it has plenty enough Calcium in it.
And you really don't need it at all if you use tap water.
Even with RO, don't use it more than 1 ml per liter unless you are buffering your Coco before Planting.
Thats when you Buffer the Coco with 2 ml per liter of Cal mag and leave it overnight.
Any other time you use 2ml per liter its going to cause Potassium Issues. Especially like you have running such low A & B levels.
Worse thing you could have done is lower the A&B below 1 ml per liter and 2 times the amount in Cal Mag & N.
See where I'm coming from here?
In week 4 is where you cemented it death.
If you just left it with A&B at 1.5 ml per liter and flushed she would have come good straight away.
Killed her with too much Kindess
