Hi there Aragon, you have nutrient burn from feeding too much, try cutting back on feed ever so slightly , the problem should stop spreading. Hope this helps ! 🚀

What do you think is causing the spotting, leaf curling, and stunted growth in plant #1? My money is on light burn and/or PH issue. I have a PH control kit I've been using to treat the water, but do you think just treating the water is enough? Using FoxFarm HF soil, no nutes yetWeek 2

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?

Browning between leaf veins!After my low humidity problem two days ago, she seems unhappy and the growth has basically stopped. I realize it should be slowing down at this third week but these brown, dry-looking areas are showing up between some of the leaves, the ones in the center being the worst. Thanks!Week 10

Grayish brownish fuzz on sugar leavesTurned my northern lights plant around today and noticed this on the back of it. Yikes! Is it bud rot, pest damage, something else?
If it's bud rot I need to get rid of it ASAP because I have 6 other plants in the same grow room.Leaves. Color - Dark-brown

Brown spots and yellowingWhat do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.Leaves. Color - Yellow

Damaged leavesI have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not correctedWeek 5
