Just a newbie, stuggling to keep them good lookin in between work and sleep. well they haven't died yet so must be kinda ok. next week is turn time, any advice would be much appreciated. :)
Light is way too close my friend
Leaves start tacoing and the edge start to curl up ... first symptoms of Mag problem ( in this case , too much light ).
Next symptoms the petiole ( where the stem join the leave ) gonna start to turn purple and it will spread to the stem while leaves are gonna turn dark green ...
Does 600w lights should be at 60 cm minimum bro.
no purple and no dark green..... but did have a calcium deficiency so had to up the cal mag in weeks 4 and 5 to max dose according to directions... 0.8ml per litre. looked like it was starting to bleach in the leaves from outside in, then when i upped the cal-mag the whitish parts started going green within 2 days, can kinda still see where it was. now green. as long as I max dose the cal mag. Also week 5 the plants are munching food like no tomorrow as I'm re feeding every 2 days as the ec keeps dropping from .8 to .4. Not sure what I'm doing wrong? any help much appreciated. cheers.
sorry got app all wrong, I've put total in 130l instead of per litre for all my nutrients. I'm slowly learning. i figured it out when the max was 50.....lol I'm at 66ml
Your grow looks great. It's awesome to see another cch20 grower here who's at the same stage in their grow! Do you use one of their recommended feeding schedules?
