Raised bumps on leaf? Need help

somewherelostbluesstarted grow question 5y ago

Anyone have any ideas what this could be? from clones almost 4 weeks old. I've noticed this on a couple leaves. Growing in Promix HP and indoors and i've never had any pest issues/seen any before. I did have some lingering calmag issues at the start but it seemed to sort itself o

Have you had any ph fluctuations? I also learnt the hard way that calmag is a bugger for causing nutrient lock out so maybe give them just water for a feed

I'm seeing some discoloration, and it's spreading to the newer growth. I have been watering at pH 6.5, but upped water to completely soak the medium. How much should I let it dry out between waterings? Organic dry amendments, mycorrhizae, and CalMag.

Never really noticed this before, but it's also been a long time since I've grown inside. The tips of each jagged leaf edge is pointing up. Just curious about it.

Leaf Discoloration I woke up this morning to only one of my strains having discoloration on the leaves. Still looks extremely healthy but I don't feel like I'm overwatering and I'm definitely not over fertilizing. Need help before problem gets exacerbated. Thx in advance.

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
