Seedling leaf diagnosis

1st time grower experiencing issues on issues. Can anybody help diagnose these 3wo seedlings? After comparing to pics online, it looks like nute deficiency, which I haven’t even introduced yet. They were both looking fine until two days ago when I switched their water from distilled to tap. I’m letting it sit at least 24hrs to dechlorinate, then adjusting pH b4 watering.

Over/under-watered? Adjusting to ‘new’ water?Lighting? Infestation? Mold? :thinking: Something else even scarier?:scream:

Overthinking. Please send help.

I’d start there. I won’t use my local tap water. They use chloramine and it does not outgas like chlorine.


What do you use?

Well your using a mix of ff soil, coco and perlite? Have you been feeding JUST phed water? Or nutes mixed in?

Yessir. Only pHd water so far. The cots r shriveled but not sure if that’s from maturity, or if they’re damaged like the others so I haven’t started any feedings

To my inexperienced eyes, the new growth looks fine. I’ve accepted that I may not know exactly wuts affecting my girls but I’m def waiting this out 2c wut happens. But I’m concerned whatever this is has potential 2 spread 2 the healthy leaves. 2 prune or not 2 prune… That is the question lol

@Nicky @merlin44 @Covertgrower @PurpNGold74 @Myfriendis410 I’ve seen ur names pop up repeatedly during my search 4 answers nd maybe 1 of u can offer some input or advice? Happy Munday Fonday everyone!!!


What is the exact model is your pH meter? Has it been properly calibrated following the instructions provided with the device?

I agree, the new growth looks better than the older growth.
I think that @Covertgrower is among the best at diagnosing problems. @AfgVet is also quite skilled at diagnosing.

Thanx 4 chiming in. My pH meter IS a cheap one from Amazon but I DID calibrate it according to the directions. Even watched YouTube videos 2 make sure I did everything correctly nd it seems 2b giving accurate readings. Puts my tap water around 7.4 and I keep measuring til it lowers about 1 full point. Aside from calibrating, there’s only a small range in pH of solutions I’ve measured with it

Here’s the exact meter I purchased

Do you have 7.0 and 4.0 test/calibration solutions? If so you should test your meter on each of the to insure accuracy.

If your meter is accurate, I would sit tight and watch the new growth as it matures to see if it stays nice and green. The folks that I tagged will likely weigh in with some excellent guidance for you.

If you don’t, to at least get a guideline if it’s working somewhat properly, white vinegar is in the 4.0 range.


And yeah @Covertgrower these solution packets came with the meter and I used these two. I did not use the highest 1


Should I retest?

I was going to test some white vinegar and suggest that too. Thanks @Covertgrower.


I think as long as the ph meter seems calibrated, I think it’s fairly accurate.
I would recommend getting some ph up or down that will help stabilize your ph in your medium. Citric acid does work, but doesn’t work well long term.
I would verify with run off that your ph is in range, and feed, as it looks like they’re hungry, but you ph isn’t in range for the plants to uptake them.
