what you're feeding with and how much? per liter/gal? do you add any cal/mag? could also be overwatering. I suspect some excess locking out P/K.
Either way you might have to flush(leech) the soil(water 3x times the medium) followed by light feeding with 1-1.5ml/L of H2O2.

I'm feeding with Expert Plant Food (its cheap). 15-30-15. One teaspoon per gallon. I've only feed her twice so far, however the soil says that it "feeds for months", so I think that's where I made a mistake. I don't add cal/mag.

Also, should I remove the dying leaves, or just let the plant do it's thing.

Hm, for a potted plant I'd go for something less P and more N, K. Esp during veg/stretch weeks of flower.
Cal depends on your water. Mg... Some plants are Mg whores, some need less, but all need it. You can use epsom salt for mg+sulfur. I would get something with a NPK ratio 3-1-2 or 3-1-4. And get cal mag additive. like dynagro folliage pro+ dynagro mag pro. This two bottle combo was sufficient for many of my grows veg and flower. Later I started playing with other stuff, but still circling around.

For now I'd leave those leaves be. You need to figure why they are doing this. Leech + light feed would be a good start. Besides leeching turns a plant into hyperdrive, you would experience some nice vigorous growth boost

It's something I do once per 3-4 weeks to leech sald buildup and plants love it

Okay, the browning is spreading still, so I'm going to do a leech + light feed tomorrow. I have never had this happen to any of my plants before, so hopefully I can figure it out.

This is a quote from another member

"That's definitely nutrient burn. To my knowledge, all miracle grow potting soil has nutrients in place already. Maybe you found some kind that doesn't, but barring that, I think you should definitely not be adding any more nutes on top of what's already in the mix.

Flushing may make things worse. Miracle grow uses time release fertilizer. Which really means water released fertilizer. It dissolves the way a jawbreaker dissolves when its wet. Adding more moisture to the medium will just release more. You could be damned if you do and damned if you don't here.

If it were me, I'd probably feel I had a better chance trying to ride it out. No more nutes and be extra careful on the watering. If the new growth looks good you may get past it.

Someone will come through and bitch about Miracle grow, but the real problem is that newbies generally are the ones trying to use it and their skills aren't up to snuff for not having control over the nutrient load. I did it too, as did a lot of people here. Anyhow, couple that together with the poor watering ability most new growers suffer from at first and Miracle grow probably isn't the best choice to start with for most of us. That being said, I'm willing to bet that the guys (and gals) here who know how to knock it out of the park consistently could figure out how to get the job done with Miracle grow just the same."

So hopefully it's just nute burn! What do you think about this simisimis?

He has a point, hot soil can be a real bitch. The only reason I did not address that to overfeeding is that plants tops do not look showing it. Signs of excess usually starts at the top, you can see stunned growth, wrinkled dark green leaves, burned tips.
I am not aware of US soils, as I'm in Europe, but flushing is either way needed. It will not get worse. But do a proper one. Like if your medium is 3gal, run 9gal of plain water. After you do so, pour like a liter of lightly fed oxygen rich water. Flushing will not only get rid of nutriend excess salt build up, but also flooded roots will turn plant into hyperdrive. It's a practice I do regardless whether I have problems or not because then for some days you experience boost in new growth, cause plant needs to pump the water out of roots. You see some nice light green vigorous circles at the top and noticeable growth within hours not days. Good luck man, and keep us pic updated

Okay, thanks so much! I haven't had time to do a proper flush today, but I will most likely get to it tomorrow. I have watered her with plain spring water the past 2 times, and I haven't noticed any more leaves browning now. So I'm almost positive it is nute burn. I will do the flush you recommended tomorrow. Thanks again man!

Okay, I have only given her plain spring water form the past 2 times. I will do a proper flush like you have described tomorrow. She's doing much better now. I'm almost positive it is nutrient burn at this point, but it hasn't gotten any worse now. Thanks for all you help man, I really appreciate it.

Day 40,

I flipped her to 12/12 yesterday. She's recovering well from the nutrient burn (WHOOPS!). All new growth is healthy and green now, which is a huge load of relief. Even though they don'y look "pretty", I'm going to leave all of the leaves that were burned. None of them are fully fried, and I figure removing them wouldn't really have any benefits. Correct me if I'm wrong on that anyone. Here are the pics.

Periodic leech is a nice way of avoiding salt build up caused problems that you would need to fix later. Growth boost comes as a plus. But to get a grip of feeding is not so easy, you have to get a feel of your soil, your nutes, your water. Also different plants react differently. But to me this is always challenging and 'tis what makes it fun

If those leaves are still green keep it, plant will shed them once it will not have any use of them. Glad it's kicking again! Keep it that way

Hey everyone,

So I've been really busy at work the past two weeks and haven't updated as often as I would like. Also, with 12/12 cycle, I come home and she's already sleeping, so I haven't taken as many pics recently.

The nute burn has slowed down, and all the new growth is still looking good. I finally had time to do a good leech this morning, so hopefully she'll be nice and perky for pics this evening or tomorrow morning.

I'll post pics asap. Peace.

So what did you do for leeching? What did you feed right after? Did you add any h2o2 for extra oxygen?

After suggesting it, I went ahead and did that for my plants. Plants response still surprises me ))
