I think you are burning them with your nutes... Try to lower PPM of your nutes.. Maybe too much P....

Peace and love,

something is wrong, with a .5 conversion you should have ca. 1000ppm, with a .7 conversion, you should have 1400ppm. check you conversion factor

it should be .5, not .7!

thats too low, together with a bit of IR it can lead to what you are seeing, by your pics it could be moisture stress(rolled up edges), increase your RH to 50% (wet towels etc., reduce air circulation).

what is IR? Thank you for the replies..

mace_ecam · 02-20-2006, 10:05 PM

IR stands for infrared radiation, also known as radiant heat.
IR is emmited by the bulb for instance.

whats your conversion factor?

TDS Factor is .7, I just switched to 12 12 yesterday, plants are all about 14 inches tall.. ppm is 1080, ph is 5.7 what are your thoughts? I got the RH in the 50% rang..
