First time growing in coco. Using h3ad’s formula with 1gm epson salt. Strain is white widow about 1.5 months veg in 7 gallon smart pot. Been having this discoloration (sort of light colored spots) on most leaves. Looked up as much as I can and looks like maybe potassium? What do you think. Thanks in advance!

I’m using mother earth coco 70/30 coco/perlite. Supposedly prebuffered so i didnt precharge with calmag. Also using gh flora micro + bloom 6/9 + 1g epsom salt. Strain is white widow that i started from seed. I have this one growing in a 7 gallon smart pot which i believe may be too big.

I snagged a few leaves off and look underneath and didnt see any pests but the more I look up pest issues it appears to be a sign of thrips.

can you check EC you feed and EC of your drain ?

your containers are big, your plants to, they are in since 45 days or so

they are maybe only hungry
but try check the EC in and out to be sure

do you have big drain ? I dont know much about the perlite parameter, ut with such big pots i would do little or medium flush once a week and multiple "not so light" feedings a day

ww is old strain oldy goldy shit

still check for insects, because spots on leafs are very often sign of the beasts... lol uncool i know...

my 2 cents

I had to add cal/mg in coco under LEDs. I don't know if Epsom salt provides both. Are you watering until you get run off?
