I can't figure this out for the life of me..

Ok so really a big hurdle for me is figuring out nutrient problems..just with all those charts everything looks like everything else so..

I use t5s..it's a homemade soil..she is a little over 4 weeks flower...RO water and the feed is 2-7-4...the ph is rine ...I know the feed is a little low on the K side so that's why I was looking into it as a def and it fits the description butttt so does a few more things!!

I just always look to long and bang my head against the wall literally..

And as you can see it starting to curl and shrivel to crisp and die

What brand is the feed? What does the instructions say? how much did you mix? K is not to low. P is to high. You will be better off with a balanced feed. 2-2-2 or 5-5-5, something of the sort. 10-10-10 or higher are the same as lower numbers you just mix less. If one of the numbers if off by one or so that is ok.

It is nutrient burn. What is in your homemade soil? Why feed on top of a mixed soil? Was it showing deficiency before you fed?

What are your temps? T5 can get hot.

First I live in a full prohibition state and I have already stay ordering so much shit to my house so I was trying to cut back, and just picked up what the local nursery had..Dr. earth golden bloom.. and I cut back like crazy to the instructions...I mean deff around a 1/4 to what it says...and this is the only plant doing this in the soil,and the kicker is it has a mutation called variegation (deals with chlorophyll) (Shark Widow) so it's hard to tell what's a nutrient problem to the mutation but yes imo (obviously I could be wrong) it had all signs of needing fed...this was noticed 2 days ago and yesterday needed water so I just used RO water, ph'D with adequate run off...

I I'm no where near an expert, let a lone a great grower but it isn't my first round and I really thought I was starting to get the hang of it,but this kryptonite

It's deff something I shouldn't have done and I'm kicking myself for doing so

she be oding on nutes had a few of them flush and use just water stick in corner may get a oz

On the whole plant has only about 3 leaves that are like this, a lot of what's in the background, well I'm sure it plays a role it those close ups to... it has a mutation called variegation 100% forsure and it deals with chlorophyll, which makes your plant green ...mine (it's not a whole plant mutation, just different sections ) is white and yellow at some spots, there's a couple threads on here recently where a few of us have this... (I don't have them saved but I'll try to find)

The rest of the plant looks fine no where near as bad as those....I've since haven't fed anything

mine whole plant looked like that leaf pic. Lol....

Buy Alaska Fish Emulsion. It's sold everywhere.It's 5.1.1 or 5.0.0. But flush like hell now. Your homemade soil - you didn't say what it was.

I have it written down somewhere for the exact but really a local base soil, perlite, bl meal,Bo meal,ewc, some epsom salt, d. Lime...a few other tidbits but what I'm thinking it was a shitty stir job on my part....because really this plant is, well was showing defficiency

I'm a recently retired medical professional. I believe not only in reading but in reading information that conflicts with what we already "know". While a lot of older RNs didn't like the newer ones too much I always did. They know so many things that are new and they are fresh from the learning mode (hopefully to stay in it too!)

That said - I believe Mandala Seeds is successful enough and has been around enough years to pretty much know how to grow pot.

From Mandala:
"
Common Mistakes

With quality horticultural grade soil you do not need to mix additional perlite. This is a completely outdated practice from 30+ years ago when there was a much smaller selection of horticultural potting soil available for non-commercial gardeners. Nowadays all quality horticultural grade soil for flowering or potted plants is manufactured with a perfect air-to-water ratio.

• Do not use sand, coco fibre, or hydro correls in your potting mix. These materials do not contain any nutrients, which can lead to a deficiency in pots when plants grow larger.
• Hydro correls change the pH of the soil (it becomes more alkaline with pH 7-.
• Mixing potting soil with considerable amounts of coco coir can lead to a large percentage of male plants.
• Nutrient deficiencies and nutrient overabundance (ie. up to the point of serious overfertilizing) can both cause serious changes in the pH and salt levels of the growing medium. This affects biochemical changes in the plants during sexing or pre-flowering and can increase the ratio of male plants or trigger the appearance of male flowers on females."

Old Turkish proverb "No matter how far you have come when you discover you are going the wrong way then turn around."

Just flush with good water. There's probably so many nutes in there you could veg another crop after this one is done.

People say its too much nutes, if that would be the case all of your leaves should be burnt all tips from start of leave to the end of it, so i would exclude that. For me that looks like a strong PH problem or something is wrong with your roots, either they have no oxigen (too much watering perhaps? If theres no overwatering signs check ph at root zone).

To check ph there you need distilled water, and from the bottom of the pot get a pen and get some soil from there in a cup, mix it with distilled water and then check the water PH, if its not in the right range you need to transplant into a new soil and start feeding micronutes and nutes.
