Plant size and leafs showing nutrients deficiency?

Hey guys, I usually grow autoflowers, but thought I’d try photoperiods, for a bigger yield, and bigger, tighter buds.

I’ve noticed that the plants haven’t shot up much, and they are about 8 weeks old. Should I flip them into flower now?

Also, can anyone tell what nutrient deficiency this plant has? The other 2 seem fine, it’s just this one plant.

Pictures will be uploaded shortly

Are you adding Cal-mag


I actually have not for the last few weeks. I’ll add it in to tomorrow watering, and hopefully I’ll see a nice response

Feed them girls, nute deficiency, I suspect potassium from yellowed margins dark green interior.
Not (na) PHing that water/nutes maybe a lockout.


I need to invest in a proper ph tester I think


Apera or blue lab both around 50 bucks good choice for Digital ph meter.
