they are white rhinos, i was told they are light eaters and to max out at 1000ppm
The max temp was 89, i just checked.hogwild said:
I have an intake, and the air is constantly being sucked in and out to the scrubber
um, what is light bleaching??mtnjohn said:
temps are always in the 70's
i lowered the ppm just now, assuming it is nute burn? I was told they dont need much nutes. and they like about 800-1000ppms.
its not nute burn dude. If your paranoid change your res and start from scratch. If your going to start from scratch start out at 5.6 Ph instead of 5.8.As far as your temps go 89 degrees is high, but not that high, i get away with worse. If you can just increase your airflow and or raise the lights... you do have to do something though otherwise as the buds grow they will burn and then you introduce a chance for botrytis to take hold.
so i should raise my ppm a few hundred more?hogwild said:

keep the ppm where it is. if you change the rez keep the ppm and ph where it is. air temp of 89 is a little high lower to 80, rez temp of 89 is bad it needs to be 70.
light burn is when the light gets too close to the plant and burns it. and your plants are a classic case. hold you hand under the lamp for a full 5 minutes. if its uncomfortable so are your plants. funny thing about light burn is it dosent show up right away. i once had a plant i light burnt, all the leaves turned yellow and WOULD NOt go back to green.
keep the light further away next time

i dont know where you got my res temp idea. My res never gets over 72, it is mostly 70 or slightly lowerfarmerbill9 said:keep the ppm where it is. if you change the rez keep the ppm and ph where it is. air temp of 89 is a little high lower to 80, rez temp of 89 is bad it needs to be 70.

some people say to add more nutes, some day dont, oh man
guys, i dont think it is light burn, it is not that hot in there with my hand testing, and i have that same look on bud sights that are farther from the light.
I just upped my ppm by 200

if you dont think thats light burn on the tops of your plants...thats fine
but...... thats what it is...no doubt about it
it's not so much from the heat but from the intensity of light

did they go from flouros to hps??

no, they were under flouros as babies.mtnjohn said:
here they are not that long ago, under the hps
they are under 600w hps, i assume the closer they got, the harsher the light, what can i do? i cant raise the light any higher
yeah i've noticed that in my c22 with a 600 i have to keep the plants tops further from the light than most charts say and large room growers clearly get away with. i have a 6 inch vortex pulling 450cfm from the hood out the top and temps never get more than 5 degrees over ambient room temp which is kept around 70-72.. so i don't have heat issues.. but the light intensity with all those lumens bouncing down and off the white walls it really gets those plants baking in the photons. if i stick my hand under the light i don't feel 'heat' really but i start to feel a sort of burn just from the light intensity.
i'm trying to start seedlings under the 600 for the first time and having the thing 2-1/2 feet above them was keeping the leaves really light.. i moved it up another foot and now they look all good.. new growth is green and coming out faster..
but yeah in a small cab with lots of watts gotta watch those plant heights from the get go.. know your ceiling limitations and such.. lst and scrog are always helpful!

i agree. weather you like it or not, its light burn. i have had light burn on floros, especially the cfl, but also with the 4 foot tubes.
