LED light 275W 36” away from pot
Plant at day 10 from seed, started in 5 gallon pots coco/perlite

Feeding started at day 6 with low ppm around 200
Last feed was yesterday around 315 ppm
Feeding calmag and foxfarm nutes according to schedule ratios

I fertigate around 1 liter per day and i tend to fertigate close to the base of the root and and spreading outwards, yesterday a big drop fell on the leaves and i didnt wipe it off, i dont know if this is a result of the drop magnifying the light or the drop foliar feeding the leaves to the point of nutrient burn.(nothing was wrong before this) Is this fixable or no point in letting it live?
Temps:68F-72F
Humidity:65-70%
Good ventilation with no direct wind blowing.


I have 2 other seedlings in the tent that are fertigated equally and didn't get affected whatsoever but they all seem to be having slow growth.

All 3 are autoflowers if that matters with 24-0 lifecycle at the momentF9A39F4D-3897-4507-997E-9B4D57AE3F6B.jpeg5B5CA874-3511-4C1E-941B-03DEA4FB9527.jpeg5EDA6F78-B226-428B-872C-584C29A04A77.jpeg

Just use ph water at that age. Make sure your ph pen is calibrated.

I woukd bet you have burned them with nutes or your ph is whack

Its ph’d at 6.3, I'm really unsure what the cause is, its either nute burn or the effect of that water droplet or overwatering idk.

You don't have to water seedlings in coco everyday. You want the roots to stretch out and grow and not keep the coco saturated like you are. Also, if that's a true 275 watts then it might be too intense for seedlings even at 36". I'm not an expert in any way as far as LED lights go as I've just started playing around with using one. Mine is just a 100 watt Vivosun VS1000 but I had it on full power somewhere between 18" and 24" and it was too much for some small plants I was growing and they started to show signs of stress. I turned it down and the plants perked right back up. Someone with more LED knowledge can probably tell you if that may be part of your issue.

Good luck.

I don't know what height or intensity your light should be at for seedlings and I don't even know if that could be part of your issue.

Maybe @bk78 could give some insight on that.

You need to provide information on your light though to get help with that.

I’m thinking your chasing your tail. Deficit at this age? That little baby plant doesn’t need anything right now besides water and good environment. Snd less water st that… you said a liter a day!!!!! Holy shit my giant plants at end of cycle take a liter a day….. your killing em. I mean seeds this size probably need 1/2-1 oz of water a day! That’s like a shot glass. What are you doing feeding and drowning those poor babies.
Looks to me like some pathogen spreading due to lack of vigor and over watered medium.
Definitely 100% not deficient, CA or otherwise.

If a seedling looks like that then something is drastically wrong with the fundamentals, it could be the light, it could be temperature, faulty PH/TDS meters, etc. It's hard to mess up a seedling this quickly so something is way off. Without knowing everything he is doing, I would guess overwatering. What is the temperature in there?
