thanks sub,
a hand water flush to the few plants that were doing this has seemed to fix it. also watering was cut back from 2x to once a day. they are now getting a purple tint to the fan leaves. he posted pics under my name in another thread called "is this normal" ive had this before on purple strains and bubba kush (which gets purple in some spots at the end). i normally dont see it until the last couple weeks and it seems to get darker in colder weather. its never affected my yields. i think its just the purple nature of the plant. anyone?
icbh707 Reviewed by icbh707 on . leaf curling Plants are three weeks into 12off 12on. Look healthy. But the tops of some of the leaves are curling down from the vein, not tips. ppm's are 1320-1280 using GH nutrients. ph is 5.9 to 6.1. any idea whats going on? Rating: 5
