Canna always at quarter the dose and last Rezz change was 5 days ago and topping off like 2 ltrs of ro every day . Last night I turned the bulb up from 400 w to 600 w and it grew even faster .
Could it be lack of calmag ? Since I am adding the ro i don’t add cal mag before next rezz change could that be it
I was keeping ppm at 700 as when I raid it a bit I saw leaf tip burn just a slight so I backed off and ppm started to rise so u only added ro when I topped off . So by hutch much should I raise the ppm with cal mag with ? I added 2 ltrs agin now and ppm went down to 480 ...
Just did notice all clear ... No bugs or critters ...Been doing some searching on the net and looks like some sort of nute deficiencies but not sure witch one ... how high should I bee keeping the ppm at ? As I added another 2 ltrs of ro and ppm went down to 550 at the moment . And always was keeping it at 700 ppm .. .. ph always at 5.7 to 6.0 ... could it be because increased the light from 400 to 600 and these problems started to occur .
i am afraid the spots have increased a bit so getting really worried now
i changed to hps today and bumped it down to 400 again from 600 as i noticed this problem started when i turned the light to 600 mabye a coincidence i do know
so yesterday i added another 2 ltrs of ro and raised ppm from 550 to 750 with 1/2 the dose of calmag and enzine and left her at 750 ppm and 5.8 ph and in 12 hrs it raised to 780 ppm and 6.0 ph ....
today i added another 2 ltrs of ro and ppm wennt down to 680 and ph stayed at 6
what do yo think please
I don't go by ppm, can't really judge what's in the mix
Give it a few days, remember bad leaves won't get better, so watch for more leaves turning[/QUOTe
Just a quick question .All was going well when I changed it to 400 again ... Ppm was dropped so was water level and pH was rising . So I decided to raise the bulb to 600 again . And from yesterday to today it went from 850 to 900 and pH from 5.9
What do you think
