Mars sp3000, I have it at 60%, par is at 380What lamp are you using ???
Using Canna Coco Coir, its buffered. I checked the coco coir by running RO water through it, the runoff ppm's was 275 with pH of 6.1Most likely unbuffered Coco. Maybe foliar feed to correct ?
Thank you Hooterjh101Possible UV damage? I cooked by plants a bit in veg once with my sp3000 shortly after I got it. Was right around 60% and a good 24 in above the canopy.
Other than that, I have no idea brother .
That light is certainly no slouch though. Running two of them in a 4x4 now and they re fantastic. I rarely go over 60% even at 12/12. That gives me DLI of 40 and If I go any higher they start stressing.
thank you, LexLuthorIt's on the new growth, so it's most likely an immobile nutrient deficiency of sorts.
Calcium, Sulfur, Iron, Boron and Copper are immobile nutrients.
I'll do a lil research and get back to you.
Feeding 400 ppm's with 6.2 pH Runoff is 350 ppm's with pH 6.3 Temp inside the tent is 75 to 80 degrees in day time and night temps are 65 to 73 degreesWhat is the temperature of the nutrient solution?
Solution temp is 68 degreesFeeding 400 ppm's with 6.2 pH Runoff is 350 ppm's with pH 6.3 Temp inside the tent is 75 to 80 degrees in day time and night temps are 65 to 73 degrees
I just changed my reservoir solution, only using canna coco A & B, Cannazym with total ppm of 350. Then a added 9 grams of epsom salt which increased my ppm's to 415 with a pH 5.8Solution temp is 68 degrees
LexLuthor, I want to thank you for your infor. I was getting a little lost on trying to figure this out. I am looking into the immobile nutrients.It's on the new growth, so it's most likely an immobile nutrient deficiency of sorts.

I do aerate my reservoir with a extra pump, the water(solution) is always moving. I believe on meter is on the .5 scaleWhen run-off EC is lower than intake, it could mean you are under-feeding.
A plant that size in week 6 of veg should be at least 1 EC (500ppm), if using the .5 scale. If you are using the .7 scale then 1 EC equals 700 ppm.
Do you know what scale your ppm meter is?
And do you aerate the reservoir?
pH seems spot on for the most part, so we can probably rule that out.
