Needed some help diagnosing my one lady, mid level leaves are starting to show signs of spotting, my ph is perfect at a constant 6.5, environment is 25℃/50-60% humidity with the light on and 21℃/50% humidity with the light off, the only thing I did 2 days ago was change the brand of nutrients, could this be the cause?

Over watering it looks like to me... Do u have drainage holes in the bottom of your cup ... If you do stop watering so much .. the less you do the better when they're that little

Nugs, probably a calcium deficiency from early on, where you knocked off a growth point and it never healed. Everything and anything probably climbed in afterwards. Take a close look. See if it is on the top, bottom or middle where the rot is. I bet it is on top, right where that wound was made.

Could also be a boron problem, low B blocks Ca uptake. As does high K and Mg and too much water.
Thanks for the input Slown, yea I don't think I put enough dolomite lime in my supersoil. I'll b supplementing w calmag next grow. I'm Being that I'm in Hawaii
Humidity is bad here in Hawaii. Mold and fungus are serious issues. It could also be borer bug. Nugs are looking good!

I've been having this problem growing in Hawaii for 3 seasons. Some kind of black spots come on the stalks then branch will turn yellow then brown then die while the rest of the plant is still healthy looking .also some leaves have yellow and brown spots...i use rainwater and pH seems fine I grow in a big greenhouse with open sides plenty air flow... I live in a jungle it's 85° and humid... I've tried watering azamax into soil....I've tried spraying azamax...sipnosad...serenade ....nuke em...safer powdery mildew cure... even tried avid but nothing seems to stop it...lmk if anyone knows the cure or recognizes these problems..mahalos

Any ideas on what this could be? I've read it all but having problems diagnosing... First indoor grow. I'm in the second week of veg, running 2ml h2o2, 3ml of calimag, 4ml micro, 5ml grow, 1ml bloom, 2.5ml roots excel, and 5ml diamond nectar in a drain to waste. Flushing now with a light foliar or seaweed extract to see if I'm overloading them. R/o sys with ppms of 600 on a 500scale. Anything will help! Thanks
