Cropical Fruit mutant and sickly

[theSmilingBandit]

I came home from work today to find this discoloration on the leaves of one of my three plants. They are all autos, and the other one of this strain is doing great, it's always been much bigger than this plant as well. You might also be able to tell by looking that it's a mutant. My other plants have always grown out new stems 2x2, north/south and east/west. This one grows three at a time, in a triangle manner.

Strain: Cropical Fruit auto
Soil: 100% Happyfrog
Nutes. I finger raked in 1/2 cup Happy Frog Fruit and Vegetable (7-4-5) organic fertilizer a little over a week ago. Nothing else.
Lights are a little over 500W mars Hydro LED on 20/4 schedule.
Plants are almost a month from seed.
I have a DIY yeast CO2 generator in the tent that I like to pretend is doing good but probably isn't.
I watered two days ago and it is still pretty damp. I am worried maybe that the soil is too wet. The diseased part fills papery thin. I added a fan. Any other ideas, guys?

...tri-nodal plants are fairly common from what I've seen; some are mutants doing this from the start, others start doing it later in veg,... usually they're fine growers, but not always,.. How high up is that light? And if you can, get me normal light pics... LED/HID are crap for diagnostics! Unfortunately, soils have been something of a gamble these days, many bags of HF and OF showing badly acidic pH (low 5's! ) .... Checking pH is best done in-pot, direct readings, with a quality pH probe (Accurate 8 is a good one for the $)... otherwise it's the PITA run-off method, usually dubious in results too... we have an improved method here though that helps eliminate some error sources -- https://www.autoflower.org/threads/...-testing-and-ph-estimation.41733/#post-928975-- ... the organic ferts take time to break down and become available; do you use inoculants or poop teas? Wise to do so with organics, they're critical to nutrient cycling and availability!

Lights are about 20" from the plant. They're the older Mars Hydros, 600 and 300, I think? Think it may be burned? My buddy actually ordered a PH pen yesterday. I'll report the PH as soon as it arrives.

I just mixed the fertilizer in. I figured the fertilizer in the soil would hold them until the new stuff started breaking down. This was always the smallest of the three plants, I doubt it used up its nutrients before the stronger two even showed any sides of problems/

I can get a real color pic this evening. The leaves didn't brown, though. They just faded and became brittle and dull grey green. I have seen a few gnats, but I was on them as soon as I noticed, and the fly strip i put in for monitoring has been pretty empty.

Here is a pic with regular light. Plant has perked up a little, even as the leaves have decayed a bit more.

Looks like maybe the leaves are getting wet when feeding? but it does resemble a ph issue

I think it ended up being nutrient (probably Mag or Mn) due to alkalinity. I PH'd some water down to 5.5 and mixed in epsom salts. It seems to have halted the progress of the dead spots. They aren't growing back, but new growth is healthy. In the future, I may mix in a teaspoon of epsom salt into each pot before I start growing.

I have to say I was really disappointed in the response time around here (Excluding you two guys that took time to help me). Are these forums unusually dead, or was my post unusually poor?

It's usually pretty quick to get a response, being the Halloween weekend, all staff are off and everybody is kicking it in the live stoners room. did you start a journal on this grow? post up a link if you did, if you haven't, think about doing one, you'll get a lot more attention having both this thread and your journal to try and reach out. good growing man!

Oh and one more thing, if you're trying to reply to someone, expecting a response, use the @ symbol followed by the persons user name, no space after the symbol, that way, when that person goes on afn, there's an alert that someone mentioned them, then they'll get back a lot faster @theSmilingBandit

... still smacks of a pH issue, and there's not much to do besides flush when all else is in question, next step kinda hinges on the pH reading,... your post is fine, delays happen Bandit,... this is a volunteer staff, and sometimes life gets priority,.. I was busy trying to save harvest from shit weather

Good to hear it's halted... light distance is fine; it's definitely not Mg, or the very very rare Mn defc., symptoms don't match,... the one leaf with two-tone coloring is a mystery! might be more than one thing wonky, and this muddies the diagnostic waters,... off pH is the [HASHTAG]#1[/HASHTAG] culprit behind such things....
