Looks like calcium deficiency starting on lower part of the leaves. .1ml seems low but I'm not sure the source that you are using. 1ml per litre of water should help correct this in 7-10 days.

Brown spots on bud sites leavesHi all,
I’ve been getting these brown spots in the past 2 weeks, mainly on the top leaves located nead bud sites.
What could this be? Ph is ok, I’ve already tried to flush her, Rh is around 45%.
This is day 65, ~20 more to go. Will this affect the bud formation or quality?
Ty 🙏✌️

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

VPD related leaf issue? Brown spots, don't think its Cal related. Pls, any help would be appreicated.Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months

dark, curled downwards and brown fan leavesWhy are the fan leaves dark, curled downwards and showing brown marks originating from the edges? Had an issue of dark and curled leaves for a week or 2, did think it was getting better (N2 deficiency) but now suddenly after not watering for a day the leaves are going brown.

Brown spots/yellow tips after accidentally breaking a bladeHi!
I accidentally broke an older blade from one of her leaves, and after a couple of days that leaf started getting brownish spots and slightly yellowing tips.
Is this normal to happen after a broken blade and will eventually die off? Or is this any sort of deficiency?
Thanks !

leaves dry and curling upGelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches
