Help

Hello everyone, I've been noticing these colored spots on my plant. It's at the top(Kola section). What is it? My wife says it's light burn but I'm not sure.



50 50 COCO & FFHF
315CMH
CANNA NUTES & KING KOLA BLOOM BOOST
6.4 6.5 PH
69-75F 40-50RH

Cheers, Dankus.

Looks like a calmag deficiency to me. Don't quote me tho.

I usually water with RO water. Recently saw that RO water is "empty water". I switched it up to my tap water, but it's decently alkaline, about 8.0-8.4PH. Let's see if this does anything for it




Quick edit: I'm not watering them at the PH indicated above lol. 6.5ph is my usual.

Coco likes lower pH about 5.8-6

What is the EC/PPM of your tap water?

Around 1100ppm I believe

Holy shit. I would strongly suggest you buy water. That’s incredibly hard. Do you drink it? Does it stain fixtures or leave deposits on them?

Water is usually hard mainly due to calcium carbonate. Among other minerals. Excessive calcium can cause nutrient lockout. Check your water utility’s latest analysis. It should be online. The TDS is the figure you want as well as what makes up the analysis such as magnesium etc

I don't drink tap water because of its hardness and quality. It leaves extreme calcium residue on most metals after a day or so. I'll check the page out
