Strange problem I can't figure out...

Hi all,
Here is my Critical autoflower, 31 days from seed. Grown in Biobizz all-mix. 400w HPS (just moved from 400w MH). 11L pot from rooted root riot cube.

Current nutes:
- 2ml/l Biobizz Grow
- 1ml/l Biobizz Bloom
- 0.5ml/l Plant Magic Magne-Cal+

Previous nutes:
- Used 5ml/l Formulex in week 2 (without above nutes)
- Used 5ml/l Nitrozyme in week 3. Single dose.

I have a strange problem where the leaves are droopy and random deficiencies/burns are showing up halfway up the plant. The tip of the leaf turns yellow very rapidly and eventually turns crispy, just like dry leaf. Lower leaves are not yellow. This isn't particularly a problem, but the drooping worries me and wondered if it was a symptom.

Last feed was 2 litres of water yesterday evening after the soil was bone-dry and the pot was light-weight. The drooping might sort itself out over the next 48 hours if I've accidentally over watered it, but I have other plants of similar size, grown/fed/watered in the same conditions (different strain) that have been fed similarly which are not exhibiting these problems.

I have looked and cannot find anything on this. I'd be grateful if anyone can shed any light on this. Thanks :)
