Nutrient burn?

Looks like it to me. I went with the recommended dosage of GH series on my first plant and the leaf tips look similar.. I'd definitely check deficiency charts and ask more experienced growers tho.. gl my friend

We're going too need a lot more info. What is your soil, indoor or out, watering, temp, ect... anything you can think of.

Chafin,
The little plants need very little nutrients and can get it from the soil. That's why people use soil.

So hold off feeding at least for 2 or 3 more weeks and then start very slowly...maybe 1/4 strength and work your way up from there.

Yea I figured it was from nutes. I've been feeding at low ppm (around 250-300) but I guess even that was too much.

Hi Chafin,
There are a couple things at play. Your soil isn't one commonly in use. So it's hard to estimate how rich in nutrients it is. But now you know.

And then there's the strain you are growing. Some are highly sensitive while others are very rugged and will tolerate more.

The good thing is that you haven't really hurt your plant. It will recover fine. Plus you learned some things... ;)
Cheers,
JD

Good deal. I'm switching to foxfarm ocean forest after this grow. We just had a bag of this laying around so I used it.

Chaf...
Seen lots of seedlings burnt with FFOF alone...so use a weaker seedling mix to start and transplant up to the OF once plant is bigger. Other then the tiny tip burn...your little girl looks happy and perky.
Cheers,
JD

Update on plant. What I though was nute burn might be something else. It has spread throughout the leaf in the form of copper colored dots on the leaf. Has not spread to new growth and is only on the 2 lowest leaves.

Bummer Chafin,
How many plants did you start? Is it only the one that's showing the spots? Lots of leaf fungi show brownish spots...but hoping it's not. Try and get a better picture under natural spectrum light.

Chafin,
Very odd that only one leaf is effected. If it were progressing nutrient burn...wouldn't you think it would show on a few more leaves?

Just watch for awhile. Don't touch it and spread it around...on the chance that it's a fungus.

I might even be tempted to cut off that leaf...but I am not telling you to. Maybe you'll get another opinion.

I thought about cutting it since it was such an isolated problem. I just don't want to stunt the growth of the plant too much. The rest of the plant looks perky and healthy though.

Do this please.
Also is there good ventilation and air movement? RH in control? Poor ventilation and high rh can lead to fungal growth. Does that seem likely to you?

RH spiked for less than a day. Ventilation is good. I have a fan blowing on them. I suppose the problem could have come from the spike in humidity. It jumped to nearly 75%

Doesn't look like bugs. More likely a bit of fungus from being a bit too moist close to the soil. Doesn't hurt to look closely for bugs under the leaves tho any time you see spots just in case. Especially with mites as one or two can be dozens a week later then 100s a week after that. They leave little white/yellow spots randomly all over the leaf surface. I'm just getting over a nasty mite infestation and you don't want any of that! :)

Deficiencies or nute burn affects more than one leaf at a time and I've seen a lot of plants in trouble because people are too quick to start tossing more stuff in the mix trying to fix a non-existent problem.

I wouldn't cut off the leaf unless it seems to be spreading. Make sure you have good air movement that includes the base of the plant so moist air isn't trapped around the base and you should be good. Stem rot can happen too and that will kill a plant dead!

Plant looks really good otherwise.

I have a fan right on them and it has been spreading that's how I noticed it. I got the humidity back down to 50%. Looked over the plant with a magnifying glass and saw no mites. Will leave it alone. It's only day 14 and it doesn't seem to have stopped growth at all. If it spreads anymore I'll snip it. I appreciate the quick responses. Everyone on this forum is so helpful aside from the couple of people I've seen that don't offer advice or help and just mock. Otherwise a good community.
