can be a cal mag deficiency, but before check your ph (has to be something like 5.8) and the power of your light (too close/ too much power etc)

I think it was a cal mag and everything else too. I believe I was just under feeding them. Thanks for the help

Why are all the leaves on the upper half of the plant perky and the half way down start drooping off? Even the ones getting plenty of light. The soil is not that dry yet either.

Bugs or no
Do new cannabis leaves sometimes have defects or missing pieces? Mine seem to have a few missing spots and I’m wondering if it’s bugs or something to keep an eye on?

Accidentally ripped off a fan leaf ='(
Hi there, Today I was screwing around with photo seeds in rapid rooters and I moved a sticky bug trap that landed on top of my 12 day old plant and ripped a fan leaf off.. I just wanted to check with others to see if this would cause a lot of stress or stunt the auto? Thanks!

Phosphorus? Potassium? CalMag? What is going on here?
So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Stained looking leaf discoloration..?
Anyone have an idea what is going on with these leaves? It looks like a stain but up close with super zoom, you can see almost little white dots. Can mites start on top of leaves? There’s nothing underneath the leaves Thanks
