Thanks. Briman.
I have done the 24 hours off and put them on 20/4 now Also found today that the one Cheese I had in flower wasn't a female!!!!!! Not ever having grown a different strain, I thought the flowers looked strange, but I suddenly realized it was a male. Always had feminized seeds so was not on the look out for males. Never encountered one. Wow. Feeling pretty stupid!:no:
Took him out straight away of course. Can having a male plant in there have a bad influence on the girls? My partner has the same set up and the same problem with the girls not wanting to go into flower, so I doubt it was the cause of them being so reluctant. ...Anyway. They have had a grow spurt overnight and have all grown several inches, emptying the reservoir in the process. Something is definitely happening. Let's hope they are in panic mode and start to flowering properly now. Everything crossed........
