Nutrient lockout

Follows me like a sick puppy. I’m growing in coco. I need some help! I use well water. Any truth to this - reverse - osmosis water prevents the ephen lockout. Haven’t tried but sure would if is the answer.

@Donaldj maybe you can help on this!

are you adjusting ph of your water in anyway? an RO filter would reduce solids and hard minerals inn your water also it would make the water’s ph more neutral ( very close to 7)

I use well water and most is around 7.0 pH around me. You need to be at 5.8 for soil less stuff like Coco.

I’m using coco in pots under led in tents. I use a cal - mag type added to well h2o some epsom salt. Ph of container runs 7 trying to get lower with a lil viniger. I use rooting cubes. Temp runs 60-80 n humidity runs a lil high- up to the 70’s. Do have some fungus knats I keep in check with neem oil. I use fish fertilizer (511) n worm casting tea for veg n beastie bloom for bloom. Also I note some nute burn at leaf tips.

If your using cal-mag you don’t need Epsom salts. That would cause a toxicity

Cal mag is only necessary if the tds of your tap water is below about 300 ppm. Epsom salts and Cal Mag are a bad idea.

How are you measuring the coco? With a soil meter or by a slurry test? If you are using a soil meter get rid of it. It’s worthless.

Do you use a digital ph meter and when was it calibrated last?

Fungus gnats are a sign of over watering.
