Nut deficiency ? weird

Hello,
Soil/coco mix currently under 400w hps, temp around 25 deg humidity around 40/50 (hard to increase under this lamp). Plants transplanted last friday (1week ago) so they should have plenty of nuts. Out of 5 only 2 show symptoms, and 1 has papery leaves and curled up at the end. 3 other plants are treated the same way and are doing better than expected. Same strain gorilla glue. Should i start with canna nuts for this 2 ? Till now they only got water ph6.5 with rhizotonic. pics attached

thanks

Is this your first soil/coco run?

When I joined here, seems like nobody did it, now lots of posts.

Anyhow, your problem is likely your ph or you didn't buffer the coco, if you went anywhere near a 50/50 blend. Run ph at 6.0.

Actually its just because of delay in perlite arrival. Soon ill be transplanting to the desired 30l smart pots and ill use soil/perlite mix. For now ill decrease the ph. But why other plants that get same water/same medium are perfectly healthy ?

Honestly, didn't see much wrong in the pics. There's some blemishes that could be salts built up in the coco if you didn't flush it or it could be that plant just wants a little lower ph at the moment.

There is nothing wrong with that plant.
They all grow different.
