Hello everyone. I'm struggling to save my plants from a mysterious (to me) problem that i can't seem to solve myself. Here is the whole story:
5 weeks ago i started with 4 seeds which turned out as 2 auto (sativa dominant) and 2 non-auto (indica dominant). Decided to veg the non-autos till auto plants finished.
4 days ago i decided to move my plants from small growing chamber to the large one. Within 12 hours they all became very droopy with upper leaves clawing down and canoeing. List of changes are:
1) Switched from 360W blurple cob led to 600w HPS (1 ft from top of canopy) in both cases since my plants showed light stress when leds were around 10 inches during early stages of veg.
2) Temps were 85 ish F day and 80 ish F at nights in the first growing chamber but second one was 65 F day and 55 F night for the first day. When i found my plants with droopy stems and canoeing leaves the next day, upped the temps to 75 F by slowing down exhaust fan. RH around 35-40%. (rh of old chamber was around 55-60%)
3) Left them to adapt for 2 days with no changes. Watered one of the plants and checked ph which was 6.4. I'm growing in soil mix so i suppose the ph is more or less in the right region. Next day watered plant (one of the flowering auto plants) showed very little improvement but rest of the garden were looking quite sad with droopy stems and canoeing and clawing leaves.
4) Leaf canoeing and clawing problems are more pronounced with the new growth.
5) All plants seem to have their growth stunted.
So i waited for 4 days to see if plants adapted to their new environment with no avail and decided to post here. I saw that some others have experienced light shock after switching from led to hps so i moved the hps to 2 ft and dimmed it to 400w while installing the previous roooms blurple leds in the new growing room but plants are still unhappy. Any ideas how i can make them happy again ?

I will upload pics in a few hours.
