wow 28 views and not one reply..are they toast?..can they be salvageable?..i found a pic online of what i'm seeing on my leaves,but mine is much more advanced..they called it Hemp leaf curl.

god i hope i dont have that.

looks like too much...

it looks like chemical salt buildup. the way the leaves curl downward is a good sign of that, i would back off the fert. and just give them plain water for a few days.

Check your root zone carefully for aphids. Do you have any little gnat like fliers around the pots? You will need a scope like you would use for trichome inspection to see the younger stages of the pest in your soil.

Anytime I see strange things going on with my plant leaves the 1st hinge I do is flush,flush,flush so the issue won't spread & kill the plant..start with flushing them incase u have a toxic salt build up then go from there

 

[dtischerd]

yea no pests whatsoever..their in a sterile environment.

and i did flush and flush and flush..they are looking a bit better.

Since you know the PH of your soil, but not the ph of what you are watering them, I'll assuming that your using one of those PH probes that you stick in your soil. Those things dont work very well at all and I wouldnt believe the reading that it gives.

There can be a ton of things going on here. Without more information its hard to tell. You say that you have a sterile environment, but your using soil, so you really dont have a sterile environment. You can have microscopic bugs in your soil, your PH could be severely off... you can have salt build up, causing nutrient lockout. The fertilizer that your using has WAY too much nitrogen in it for flowering.

So if everything has been fine up until just a few days ago, and you havent changed anything, then I would say that you have root aphids. Either that or the salt build up just got so bad that its causing lockout.
