I have read the pest pictorial and still just not quite sure what it is and don't really want to make the wrong step. I have a watering/nuting coming up tonight and not sure if I should double water (plain) or nute as scheduled. oh yah my water barrel is tap that I keep in 5 gal buckets for 2 days to evap and then add to my barrell where I keep 8 to 10 gal at all times. it is heated to around 72 and is monitored for ph which right about 6.
Again thanks for any support.

 

[MSquared]

figured it out so it was heat stress along with nutes to soon.
I have since brought the temps down to 81 they were 86 during lights on and now they are up to 65 instead of 59-61 during lights off.
I have flushed them and all seems right as rain.
I hope this helps someone out.

exactly wat i needed to be told thanks this has help keep my plants going

my plants kinda look like that as well, they are 4 week ago plants vegging out in the sun. i figured it is a (K) OR (MG) problem or both and im conservstive with the nutes. that honestly shocks me that this is your diagnosis?

 

[MSquared]

Well this is the pretty little girl just 3 days later. After correcting the heat/watering issue they have started really grow and with such a nice green to them. My point is that is not always a nute issue. thats all
Cheers
