I took my plants off T5s about a week ago. Details below of setup
Canna Coco 70/30
1 gallon pots with good drainage
1000 watt HID MH dimmed to 600watts 18/6 light cycle, air cooled.
Light height - started at 18" moved to 22"
.
PAR - 350 measured with PHOTONE App
DLI - 22
One fan blowing above canopy under light. I ajusted the angle to make sure it wasn’t blowing on plant constantly.
Tent 5x5
Feed Canna per gallon
AB - 2ml
Calimagic - 2ml
Rhizotonic - 10ml
Ph 5.8
EC 1.1
RH - light on 50, lights off 58
Temp - lights on 81F, lights off 72
PPM 800 on 700 scale
Water once a day at 1/3 gallon DTW with 20% runoff.
I have 2x6" oscillating fans in front and rear coners also blowing above canopy. I thought it might be wind issue so i turned them off. It has got worse over last 2 days. Never had this issue like this before. Always something please any ideas
I’m in coco so target PH is 5.6 to 6.0 and 6.5 is good for soil. I think after some heavy reading and looking at VPD chart it’s time to crank up the humidifier. Thought i could get away without it but not with the heat and light intensity of the HID. Thanks for trying to help tho appreciate any and all help and opions
In my experience, Taco leaves normally due to out of range heating and/or RH in the tent . I’ve also experienced taco leaves with to intense of lighting.
Veg 72°-75° 50% rh is what I shoot for in vegetation stage
Im right here with you man any idea on progress? Im thinking wind burn or light intensity for mine…bit im not sure ive also seen stuff saying possibly notrogen toxicity for my girls
Ya mine was the light intensity/heat. I got 1000w MH/HPS. Unless i dim it to 600 i gotta keep it at least 18" above canopy with a fan blowing across top of canopy but not blowing on plants. The fan constantly blowing help reduce it. Bad thing is in my experience once the serrations start on the edges if you don’t react right away they wont go away. Damage is done the leaf will surive but those taco effects will always stay. Wind burn looks a bit different from my experience
