Leaves turning yellow
Old leaves die,mig-age turn light green,new stay green.Is this normal for just week 4 of flowering on my auto? Do you think it might be ready sooner than week 11? Or is it just a problem? "feeding/watering every 4 days,never used cal/mag supply,medium=soil light" Thanks growers

Puntas de las hojas amarillas, otras en garra y otras quemadas, que puede ser? Las plantas están en la 5ta semanita de crecimiento y ya pase a 12/12!!
Ayer regué mis plantas con los fertilizantes grotek colocando exactamente lo que me muestra la tabla en crecimiento y hoy mis plantas amanecieron así, no sé si es por el calefactor que tiene en el medio o por el monster grow que aporta demasiado nitrógeno. Que pueden tener??

I’ve had a cal/mag deficiency last week which was treated through the week with calmag and no new brown spots, however leaves are still yellowing. Is there anything I can do about this ?

Burning Edges/Yellowing and Drooping?
The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?
