Mongodudu is right, your girls is needing some cal/mg but dont just add on top of your other nutes. Reduce the other nutes ppm by the amount ppm of cal/mg your gonna give. Cheers

Magnesium mate. Calmag should help her out, if the pH levels are correct 👍🌱

N starts with light interiors and dark edges and before making two floors there is already at least one yellow leaf usually, so that's not your case in my opinion, and man if your calmag is 8-0-0 is shit in my opinion you can't use it in flowering

I'd say Nitro,
But i'd also use my CalMag, because it's NPK 8-0-0.
May you have a look at yours.
Good luck🤞

No N, go with calmag to enrich the soil with cal mag and micronutrient

Yellowing and lightening of leavesMy back-left plant started to slightly yellow on me from the bottom up. Front-left is also lighter than the rest. Is this a feeding issue? Do they need more nitrogen or did I overwater them? Appreciate your answers :)Week 12

Brown/yellow/purple leaves inThis started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today.
I'm not worried at this point, just really want to know what's happeninga month ago

Fatal ovewatering? Will she survive?Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start.
Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?2 months ago
