Brown spots on tips of some leaves
4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼

Should I cut these off ?
leaves are no longer crispy and dry but are still rapidly changing colour, not sure if I should cut them off or let them fall off themselves ? if I cut them off would it be beneficial ? not sure if the plants still putting in energy to keep these leaves on the plant or not ?

What is causing my leaves to turn dark and dry?
I'm growing 3 Gelato #33 plants in a DWC 5 G bucket setup. Same conditions for all 3 plants, but one of them is experiencing dark spots on the leaves and now they are beginning to shrivel up and dry out. The newer growth looks okay, but might not last long. What can I do ?

Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

I already posted it, but it's better to see here and it continues to spread
This appeared after a strong storm, but it doesn't stop spreading..two guys told me it's from the wind, as I assumed, but with the fact that it's spreading further, I'm worried
