First grow looking for help?

Hey everyone, new to the forum. Quick rundown of what I’ve got going on.

blue widow strain
under led lighting 18-6
Fox farm Happy frog soil
Roughly one month in from when the seeds were planted.
Room temp 22
Humidity is around 52%

Anyway I woke up this morning and went to check on them and found them looking rough. The edges are curling up and on some of the leafs actually getting brittle?

I’ve been trying to self diagnose but I’m not sure, any advice at all would be greatly appreciated. Thanks in advance

Sunburn.

As in my lights are too close or too hot ? I have the LED at about 50% 3’ or so above the plants ?

Could also be your light is no good for plants.
I had a burple that burnt the shit out of my plants even though it didn't have much power.

Would it have come along this far with a bad light ?

Sorry guys, bump

How big of an LED? Your plants look as though they're getting a little too much of it.
You're also showing multiple deficiencies along different plants which would cause me to first be sure of everyone's pH.
Good luck.

Thank you, I bought some ph down today. Going to start there. How big in wattage ?

Yes, how large of a light are you using, what kind, etc?

Why do you feel pH down is the necessary move? I'm curious.

I’m using a cheap moisture and ph garden probe. The gauge is reading almost maxed on the high end of the visible ph scale

When I get home I’ll try and get you some more info on the light, thank you for the responses

What kind of lights do you have? Most LEDs call for 18 to 30 inches above canopy for veg. Check PAR values.
Is there moisture/condensation in your tent when the lights come on? Excess moisture at lights on with an LED 3 inches or so away, will burn your babies.
And BTW, those soil meters are crap, inconsistent at best. If you want to check PH get a PH/PPM pen and some PH up and down'''I personally don't use either, they're a waste of time in good soil.

I’ve got the light above canopy by about 30”
It’s a higher quality aquarium LED light that I’m using for now until the new one is delivered.
So you are saying I shouldn’t bother with ph testing or? Sorry if I misunderstood

No, I'm saying that the probes are crap and not accurate, a PH/PPM test pen is much more accurate and only about 10 to 15 bucks for a descent one. I have a pen somewhere around here gathering dust

Actually if you're using Fox Farms soil you shouldn't need it, the soil is made to buffer PH to between 6.3 and 6.8...see no PH

Those plants look great and yeah I’m using happy frog. If you think that the soil should be ph’d fine , what do you think I should be looking at ? ive read that happy frog can be too hot?

So there you go ....... aquarium lights are high in UV, not suitable for growing plants.
UV sunburn.
