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!

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.

Hey, anyone got any idea or clue what's going on?I thought it was a manganese or iron deficiency from an early watering with high pH. Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly. She seems to be getting better slowly.. I think. Thanks for taking the time. :)

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

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!
