Bud Burn

What would cause the small leaves in a couple of cola’s to burn? Plant has been doing well and watering as usual. They just popped up overnight and the outside temp is in mid 90’s, not in mid 100’s like last week.

Def looks like nute burn. I’d cut your nutes to zero for a bit then reintroduce at 1/2 strength and slowly build up.
I pretty much never feed at full strength.. I use MaxSea and am in my own soil mix

I think I figured out at least that it happened two days after flushing plants with seldgehammer!! I was following them fox farms schedule. I’ve read that some other people had the same thing happen to them. Hopefully the plants won’t die. They have about 4 weeks left and we’re looking really good.

When in doubt flush with fresh water

Doesn't look like burn to me...otherwise it would be affecting all the leaf tips. Looks more like a fungus or disease imo

Thats actually bad advice.

Huh?

arbitrarily flushing plain water through a medium at the first sign of a problem is bad advice.

I'll keep that in mind but I never do anything arbitrarily but if i get in the weeds I always flush...it has saved more times than not

I will for now on. I’m new to this and thought I was doing a good thing.

the fact that it happened two days after flushing plants with Sledgehammer I’m not sure it’s a disease. Plants were lush before the flush. I’d been using nutes for six weeks so thought they needed a good flushing. Hopefully they’ll rebound! If not it was an unfortunate grow experience on my first try.
The next grow I’ll acrually know what to do. It’s been an incredible education. I thank everyone for commenting.

It’s possible to flush out nutrients, but not in two days. What kind of container are they in? From what I can see in your pics it doesn’t look like over watering. Those leaf tips look like nutrient burn. Did the tips start out a yellowish color and then brown?

The other issue if you are watering too frequently is that you could develop a fungus in the root system if you don’t give them a chance to dry out a little between watering. I feel like I’m on the hairy edge of that with our temps in the mid 90’s - lower 100’s for the past few weeks it seems. They’re sucking down tons of water every day, even the plants in my 100 gallon pots are wanting daily water, every other day at the most.

You also look more like 6 weeks out! Rule of thumb is if you think they’re done wait another week.

sledgehammer doesn’t really have NPK and is just yucca extract which is commonly used as a wetting agent, so it could be overwatering
