First time grow - Nutrient burn or Deficiency?

Hello! I just started my first grow and I’m seeing a bit of discoloration on the ends. I’ve been researching and researching, but since this is my first time its hard to tell what exactly going on with my plants…

Strain(s): 1 Green Crack, 1 Sweet Tooth… Both autos. About 3 weeks old from seed.
Hydroponics. DWC. Indoors.
PH: Currently 5.8 but lingers between 5.7-6.0 f
1200 LEDs in a 3x3x6 Tent
Temps: Day - 77F Night - 70F
Humidity: Day - 55ish Night - 45ish both run with a humidifier on high during day, low at night.

As for my PPM, EC… I believe I just check my water that they’re in and it read 675ppm

I was just on vacation for a week and my husband had to take over. Apparently he was misting/watering the rapid rooter with the res. water once or twice a day which is why I am thinking nute burn? What do you guys think? Pic of setup and plants.


Looks like slight nutrient burn nothing horrible unless it gets worse.


Just a little old nutrient burn. Look at new growth to determine how the plant is doing presently. New growth looks really good, so I wouldn’t stress anything :v::bear:


Thanks guys! I wasn’t sure if it would continue getting worse so I wanted to make sure it was burn and not a deficiency. :slight_smile:

Kind of…but, the leaf tip is resting on the medium. No issue at all, I feel


I did not mean to contradict anyone but, we need a “support ticket” here.

A lot of times we need to look at what is in front of us. Yes; I agree that you monitor new growth to judge whether or not this plant is healthy and just going through growing pains.

Thanks, nice to be here. I’m hoping to learn a lot about cannabis growing and I’m sure I’ll find great resource here. As for the support ticket… I thought I had written most of that in my original post minus a few things I was unsure of how to answer

NP just went off what latewood said regarding the support ticket, but in saying that the plants look good, i am assuming your up with the PH and all that goes with it?
You will not be led astray here all good info.
