Is this Nutrient Burn or Light Burn?

[Cigarz]

Or is it something else? This plants about 30 days on PhotoPeriod grown from seed. It's a blueberry Fem. Have it under a single 480w LED Quantum Board that's about 26-30" from the canopy at about 80% power. I fed it very little nutrients and none of the other plants are showing this. They also arent as big. Is this some type of light or nutrient burn or something else?

Looks a little like nutrient burn. What are you using? Don’t get disappointed bro it could be the led’s as well. Just turn down the lights and stop with the nutrients until you see better results. It’s still a young plant and can turn it around in a positive direction quickly. Positive vibes to you bro and keep growing.

Well said. Find the sweet spot with the lights. They should pray when you have found the right percentage. Try it at 50-60% and see what they do..

The leaf you posted shows calcium deficiency, but plant seems to recover. Your pots filled with potting mix?

They seem to be too dry for my liking...

I'm using FrontRow AG (A and B) about .8g of each per gallon...

I'll run 24-30" @ 50% for a bit I guess, I didnt think 80% @ 30" would be too much for a plant this size from a 480w?

The pots are filled with Promix BX I only fed them nutes once and only 1/4th what youd normally require.

I would . I used mine (LED MIXJOY 4000 450W)at 80 and it made the leafs droop as if the light is to strong. I dropped it down to 50 and they were praying within a day.. as they grew I was able to go higher a little bit at a time.

How high were your lights above canopy? I turned it down to 50% @ 27"

Do you know how to do a slurry test on the soil.?

No whats that?

Why you want to push him to do slurry of soilless medium? It is peat, lime and perlite so what do you think your measurements you take out of it gonna say to you. I save him time. Nothing. Better forget about slurry test.

I'm starting to think you're right... what should I do? It's weird because I fed them FronRow AG Part A and Part B which have Magnesium and Calicum...

 

[Bukvičák]

I can be wrong but I believe you just not treat the medium right. There is a boomer guy running also in promix https://www.rollitup.org/t/jjs-ripper-run.1048530/ tell him some nice words about his grow and Kindly ask him if he can tell you how is he treating his plants in sense of watering frequency, feeding frequency, runoff or not etc... not sure if hes is in same promix and hes is running clones I believe so do not follow the EC he is running! The treatment you want to know and you want to do it exactly the same way he does. I am not familiar with your nutrients so can not tell you if they have enough or not...
Edit: hes is probably running also seeds... check it alone it is interesting

What EC/ppm did you feed at and what pH?

No idea on ppm/ec how can i tell? And ph is 6-6.2.

A EC/ppm meter.

A EC/ppm meter.

Any recommendations that arent expensive?
