Leaves yellowing, dying; nute burn???

About 4 weeks into my first grow, not sure what the problem is. We just recently started nuteing them and were going by the directions on the foxfarm bottle.

We thought it was nute burn so we stopped nuteing them as of a few days ago.

What do you think? Nute burn? Disease?

disclaimer: it's my first grow too

by "going by the directions" do you mean starting them off very light (about 1/2 regular quantity) or going straight in to the suggested amounts?

want soil are those girls in? (if it's FF or MG it could likely already have some nutes in it!)

you said fox farm, i assume you're using Grow Big? i believe they suggest 1 tsp / gal, but up to 2-3. when you're just starting out (4 weeks is about the right time) you probably only want to give them 1/2 tsp / gal for their first feeding or two.

it looks like nute burn to me (see disclaimer). if it is, and it continues, you'll want to flush the soil and give them a few days to recover.

ps: i believe (see disclaimer), the damage is done on those leaves and you might as well remove them, as the damaged parts will not recover

Thanks for the response. They are in foxfarm ocean forest and youre exactly right, it would still have nutes in it. I totally disregarded that. We transplanted them and added nutes to the water at the same time, its nute burn for sure.

Ok, so I should just cut the dead leaves off or the whole branch with the dead leaves?

Don't cut the whole branch. You could also leave the leaves on until there almost completly dead.

Really looks like nute burn. I am the master of nute-burning my plants and they look exactly the same as this. What I didn't realise is that potting soil is jam packed full of goodness and weed plants need about 1/4 as much as regular plants.

I was wondering about this. In the case of nute burn, couldn't it help to remove the leaf early? My logic behind this is that since the plant is overloaded with nutes, by removing the damaged leaves, you're 1) removing a very small amount of excess nutes, and 2) ideally this would encourage new growth - work on new leaves instead of keeping the damaged one alive.

If it's encouraging new growth, wouldn't this help the plant to use up more of the excess nutes (especially if it's N that's overdone - which seems common)?

Although, on the other hand, removing a leaf removes potential energy (more than it's taking to try and keep the damaged leaf alive?) which hurts it's new-growth potential, right?

so where exactly shouldu kut the dead leaf at?

You will read over and over not to follow recommended chart schedule with fertilizers, and I will always agree.

Whereas one plant or strain is positively responsive to it, another will become ill and even reach near death...
"which" is why I always have gone by instinct.

I'm SO happy that I have stumbled upon another seed from a plant that I so sadly neglected not long ago...turned out to be PRIMO bagseed. First time around, I fed it virtually nothing. Although it did well in the end, it was long after fruition where I recognized the needs.

My suggestion is always to start low and very slowly build up. I have a personal tendency to want to over-feed these days---which leads to the nute burn and fan leaves becoming damaged and useless--thus less potent bud.

During vegetation, your plant is much more forgiving when taking an isolated leaf here and there. Again though, the way it responds is defined by the strain.

I find that so long as you faithfully keep them on the same regimen (for me in vegging, that would be 18/6) you are more easily allowed the lush growth with no ill side-effects---on the contrary. ..lots of lush new growth.

But, my personal opinion is that by taking away that sad looking leaf during flowering is detrimental. One or two stripped away will not be the defining factor, but just be patient and allow it to completely die out.

Ok, so upon further observing...here's my suggestion.

Do not water it for several days. The soil appears to be compacted and too soggy.

Go ahead and take the sickly leaves...won't hurt anything since you are vegging and there is already leaf development at the node.

Last.....poke some holes in that dirt about an inch a few times......it needs aeration before watering or feeding again.

It would be wise to add some perilite and sand as well.

Next time you feed, use only fish emulsion and build up from there.

I'm curious to see how this turned out for you. Those pics demonstrate the exact problem I'm having with my recent indoor grow.

I researched long and hard at the exact signs and although it could be nute burn it also looks exactly like a potassium deficiency brought on by low humidity during veg state.

Hopefully you still check this thread and can post some pics along with what you did to fix.

I will as well. Good luck brutha!

hey there from seattle ,I have the same issues and there is nothing you can do once the leafs are burned and damaged however i have go to a new step if you can push the growth do it with a pilot burning dont water or feed them let them stress a little not die but stress and they will pull out of anything i promise do not feed them anything but pilot ags let them do what they do and thats grow i have seen pot plants grow on the side of a cliff in montigo bay where talking about a cliff you could not get to unless you fly in or swim and climb about 500ft my point being is there was no way anyone could get to her but she was growing no water food and it was around 8-9ft tall get the point let her do what she does best..and to let you know this batch is my 71st I am 42 and i have only lost a hand full of plants...let me know how it goes

Out of all my plants, the biggest one is getting nute burned... I mix all my water at once in a 5 gallon bucket. My plants are the same strain, and only the biggest one has gotten nute burn. Could be that I'm watering it more because it's a bigger plant. GO LIGHT ON THE NUTES.

leave the nute burned leaves on untill the pretty much fall off the damage is dont and the plant will continue to send the excess nutes to those leaves till its soaked it all up, most the new growth will be fine

hot soil, hot food, hot time in the ole plant cell tonight. nute burn is my vote.
