Need your expertise!

Background/Setup

• This is my first grow
• Medium - Fox Farm Ocen mixed with Fox Farm Frog
• Lighting - 1200 w LED
• 5 gal pot
• watering with water only - ph around 6.6
• Temp - 75-80 and humidity 40-60%
• Plant - gorilla glue autoflower
• No Nutrients have been added to the soil or water other then what was initially in the soil mixture

Description
Plant is around 4 weeks old. Ever since the plant grew its first set of leaves I've noticed the leafs have a "bleached look" to them.. they are not white or even that light colored but bleached is the closet description I have. I have two other plants that look great next to this one. I've looked up possible issues and the closet one seems to be Thrips.. however, I do not see any insects on the leafs themselves. Other then the discoloration the plant appears to be fine. Any advice would be great! I can add more photos if needed.

What about temps? And humidity?

if it’s thrips damage it’s the worst thrips damage I’ve ever seen on a plant.?? Really. I had thrips last time on all 8 plants but they didn’t look like that and the thrips was everywhere on the leaves and under the leaves.
I treated them with ISO alcohol mixed with water and sprayed every night before lights were out, for 3-4 days. Then waited a week and did the same again.

Thanks for the comments. I agree it seems like an issue with the roots I'll have to look a bit more into possible solutions. thanks for the info.

No problem
One thing i cant have without growing is some kind of root stimulator. As voodoo juice or root juice.
They save me from having root problems every single time.

[Meech]

Awesome! I just ordered some voodoo juice so we'll see what happens.

[CaptainWiese91]

I’m thinking more like you have roots issues 🤔

Looks identical to a “Speed Bud Auto” I had, it showed those mottled markings/spots all veg cycle. However.. it grew into my tallest, highest yielding out of the 3.

Personally I think it’s genetics, just a phenotype. But still keep an eye on her!

Yeah thats exactly what it looks like.. I'll keep an eye on her.

Your PH is too low. Raise it to 6.8-6.9. The discoloration is caused by nutrient lockout caused by low PH. I suggest yo add some nutrients and cal-mag..

[Meech]

Okay I'll double check the PH and raise it if needed to that level. Thank you!
