Very tips of leafs curled down nft

Hello looking for bit of advice? Plant been really nice since now! Switched to flower 5 days ago and the tips of plant leafs have curled down Any reason why?? Maybe to much nitergoen?
2.4-1.2m tent
2 600watt hps air cooled lights
2 nft 1000 tanks
4 plants in each
Cf on both trays are 11
Temperature is 26-27c
Ph I bring to 5.8 but creaps up to 6.1

They look healthy and green, I wouldn't worry about it. Nutrient burn or heat stress usually presents as crispy tips or discoloration. Too much nitrogen curls leaves more than yours from what I've seen.

Overwatering?

Hopefully they change in the next few days. Gunna do a change over with a lil less nutes and see how they go.

I don't think so? Nft sure your meant to leave the pump on continuous? It is a maxi jet 1000 pump and it do seem to strong but can't control.
