Tips have twisted leaves - any ideas?

[Andy]

Would anyone know what this could be? The plants are growing well, but the tips have this twisted leaf thing going on:

I think if you just wait they will look normal. They look good tho.

Tobacco mosaic virus can cause this but it's rare in cannabis. It's most likely heat or vpd stress.

Is this a clone? It's looks like its revegging

 

[TripsRabbit]

It looks like it has really purple stems, this can be strain specific or a few different deficiencies.

Nice one - I think you’re right. I’m also wondering if it might be because the mothers were accidentally put into flower and reverted back to veg. But either way I have a feeling things should settle down as you say

Yeah thats why.

Hmm - I was wondering about that too though - perhaps I should foliar feed for a bit to make up any deficiencies..

Could the red stems be because of reverting as well? And could that reduce the eventual yield significantly?

Purple petioles usually means magnesium deficiency. Have you been giving her epsom salts or a calmag supplement?

Ahh no - perhaps I should get some cal mag. My tap water’s background EC is really high, so I dilute to down to about 0.3 or 0.4 with RO water. How should I incorporate cal mag into my setup do you think? I use canna coco and nothing else
