Leaves turning yellow / brown in the middle, severe droop. What’s wrong??

[GrowGalNJ]

Help!
What’s wrong with my Zkittlez photoperiod?!? She’s had brown spots on her leafy tips / edges for two weeks, so she got a small amount of Potassium 4 days ago. It’s also been extremely hot and humid (over 90’s each day) for the last two weeks. Wrongly, I’ve been giving small amount of water each evening - hoping to help with the daily heat - so the soil is probably too moist.
She’s 91 days old, and still in the pre-flower stage.

Can anyone identify the main problem with the plant, just from looking at the leaves? She’s in the shade now, and I had brought her inside last night to cool off. She’s been droopy for a few days.

Please help!!! I don’t want to lose her!

Welcome. Over watering and under watering look very similar. Since you’re watering at night it is highly likely that the water is sitting in the medium, over saturating and night. The black fab pots are keeping the medium pretty warm, then the over saturation from the night before may be cooking the roots. Have you took the temps of your medium during the day when it’s 90+ outside? Have you glanced at the roots at all? What’s the pH of your water and where do you source the water? Tap? RO? Well?

Overwatering vs Underwatering Marijuana | Grow Weed Easy

Is a plant drooping because it got too much water, or not enough? Overwatered cannabis plants often have firm leaves, while the leaves of under-watered plants tend to be more limp and lifeless. Both can result in yellow leaves and other odd leaf symptoms. Learn how often you should be watering...

I’m using tap water, that sits in the sun for a minimum of 24 hours. Then it’s pH’d to 6.4-6.5 before being given to the plants.
I have two other plants, that look fine - the only difference is that Zkittlez received Potassium, and the other two plants didn’t. I haven’t taken the soil temp, but I can go check that right now.

If the other plants look okay and this one different because you gave P don’t ya think you should know what’s going on? It’s either you gave to much or she needs more. 91 days since germ? What’s the stuff dripping off your plant in the 2nd picture?

I'm sorry but in my opinion your plants not going to make it, virtually all those leaves are going to drop off

The Potassium I gave was dry, not liquid - so my grow mentor advised that it isn’t quickly bio available or absorbed. it only got a small amount of Potassium. To be honest - I’d be concerned to add more, now! We are questioning if it’s the Potassium that affected the plant that quickly.

As for the brown drips on the stem... not sure. Transpiration? Guttation?

That’s my fear...
I’m going to try my hardest to rehab the plant!

It's way over watered plus next time you've got to use 25 or 30% perlite in your soil mix or you going to risk over-watering again

you've probably got root rot in addition to all those Dead Leaves, honestly that plant isn't well, if I had other seeds I'd start them now, sorry for your bad luck

I’m using Coast of Maine’s Stonington Blend for the soil... I thought it was one of the best souls out there. Still need to add perlite? Will do for future seeds.

I always add additional 25-30% perlite to whatever I’m growing in no matter what. Oxygen and drainage is key.

At least you are learning as you grow , in soil mixers at least add 25 to 30 % perlite as Beach has stated. Get a new bean in and have fun . Od .
