Hey guys I’m not completely new. Have 2 somewhat successful grows but this is my first low pressure aero grow. I’m in week 4/5 not exactly sure. What ppm level should my jack herer autos be at? I’m ranging between 6-800 with a few brown spots. Don’t want to under or over do.this pic is a week old. Just signed up tonight don’t have an up to date

Jack herer feminized auto from ilgm
4/5 weeks(they look better/bigger than in this pic)
Hydroponics
2” bucket
Fluctuates but always between 5.8 and 6.5
Advanced nutrients 3 part solution and calmag
Not sure specific but Amazon special ph and ppm reader for hydro
4x4 7ft tall tent
2 600w hydro crunch led blurple
21on 3off (it’s cold here minimized getting to cold)
Pretty consistent 72-75*
Humidity 50-60%
1 8” fan blowing on plants
Not sure name but 6” duct fan monitors temp and humidity turns on and off accordingly with my specs
Home made low pressure aero
Probably 12” from water line. Bottom roots stay in water
Ppm range from 6-800 sometimes gets higher but I dilute with phed water.
Water temp stays around 66-70*
Lowe’s didn’t have all black tote so improvised
27 gallon tote run atleast 7 gallons at all times
Pump runs 2 min on 2 min off

Sorry about that. Do you have a picture of the effective leaves in question?
There are several factors as to answer your question as to what ppm’s are good. Environmental conditions, water temps, lights, air stones, how good they’re growing all play a big factor as to nute level.
The main thing is how the plants are looking and how they are responding the the nutes that you’re running. PH also plays a factor.

Can y’all show a brother some love here with his grow?
Good luck!

Your in the 400 to 700 range … roughly … exact nutes used how old plant what media and size matters(pot size)

I never check my numbers so, I reckon that I am of no help

I wish I could help but “low pressure aero” means absolutely nothing to me. I grow soil / soilless.

Looks like you’re on track for the most part. Just continue to feed around the 800 ppm, watch your ph, and feed calcium and magnesium as those are the most challenging elements to get enough of in hydro.

Thanks for the responses everyone. I’ll get some pics when I get home. All looks good except for some brown spots

@fano_man and @Covertgrower have you covered there, good advice.
Tag me with @ Nicky if you have any further questions (don’t put a space tho)

I agree with trying to narrow the swing of ph. Most of the other stuff looks pretty good. Running leds you could probably increase your canopy temps some as long as you can still keep res temp reasonable.

Running half strength nutes and full strength calmag. Little burn on tips but growing. Taking a gallon a day and growing about an inch each day

I’d say maintaining 6.3ish. Today got little high. Put gallon of 5.8 balanced it out

When you take pictures, can you take them in natural light. It’s hard to see the plant like that.
Looking great brother!
I know I know. Sorry I don’t have a portable light down in the basement and never think to bring one until I take a pic. Just keeping y’all helpful folks up to date on the grow.

Plants are 26 and 28” high which they say around 2 ft is max so I’m happy and have another week of growth to go
