Critical Orange Punch Auto (Dutch Passion)

Hey guys thanks for checking out my thread

So, as the title says I have 3 of these beauties running at the moment and they are on week 6 (38 days)

They just started their flowering stage and I have a few concerns...

Here is the setup:

3x3 tent
Biobizz all mix
21L fabric pots
Spider farmer SE3000 (80% - 90%) approx 2-3 feet away from the canopy
Nutrients mixed into the soil are: Newtirents - Magicmix - Organic Fertilizer

As can be seen from the photo below I noticed that the plants are looking pretty 'Light' in color and not as green as they should be...

I also noticed that some of the leaf tips are brown and crispy(not all just a few) any thoughts on what this could be?

I look forward to your helpful replies

(ps: Pls ignore my rusty fan... )
