So now i fixed the water PH and the PH meter and i hope they will recover. In fact they had been in a too low PH for 1 week, do you think it will hurt definitly ?

You know low pH can cause male flowers...so be wary of hermie woman!

The root episode would have obviously caused a delay in growth...

But also your slow plants might be younger?

and ofcourse the question of photoperiod! Different strains require slightly different dark cycle depending on which degree of lattitude / how far from the equator the plants genetics originated from.

Are they all the same age ?
Easy Roller Reviewed by Easy Roller on . delay in flowering Hi people, i'm currently growing grapefruit x nex haze and wwxbb from female seeds in bubbler systems with HID. My grapefruitxnev haze started to flower 2 weeks after the switch to 12/12. My wwxbb where in the same bucket before 12/12. When i put them into the flower room, i had to tear down parts of the root system and some plants suffered root rot ( my previous post ). Now they have recovered BUT 2 of them are only now showing some signs of flowers ( 4 weeks of 12/12 ) and they are not those Rating: 5
