I've been adding epsom salts at the rate of 1/2 teaspoon per gallon of water, along with 3 ml of calmag per gallon and it really seems to help!

You could probably get away with watering more every other day, and upping the nutes. How much nutes you using right now?

BeastLebanese · Dec 7, 2020

It's been a while since I've done coco so if anyone else could offer some advice, it would be appreciated.

Could be other factors at play here, like ppm or ph issues. How did you prep the coco mix?

I would spray them down with Epsom salt and water, 1tsp per gallon, to save the leaves that haven't already started to spot, and will, because they have lots of magnesium missing from their diet! For me in any kind of coco, its 8ml ca/mg+ and 1/2 tsp of Epsom salt to whatever the bitch is fed!

I'm using tap water left for 24hours and with e.c of 0.3 once I've added nutes its up to e.c 0.7

I just put my coco in my pot and watered with an e.c of 0.4

That's probably good advice! I'm a soil grower so my ratios are what I use for soil...I should have stated that!!

I can tell by some of the pics that you're not feeding to run off.

If you don't feed to substantial run off you will get salt build up which causes a multitude of problems.

Personally, I would flush with 1/4 strength nutes until the run off is close in ppm's to the solution going in.......then feed daily to run off.
