Nitrogen defciency??

Noticed the lower leaves on some of my plants turning yellow and wilting. I am sure this is lack of nitrogen, I have been using half recommended dose. Was just after a second opinion before I up the nutes???

strains are blueberry, chemdog, white widow and Pineapple Express photos 2 and half weeks into veg. Grown in light mix soil using biobizz fish mix, h&g roots excelurator, plant magic bio silicon and some great white every other water. Nutes are phd to 6.5.

If it is nitrogen I will be upping to fish mix to recommend dose.

any help appreciated.

What is your lighting and temps like?

Temps are 17 Celsius lights out and 20-23 lights on and using grow technology t5 fluorescent

Strange. Have they just been recently transplanted or have they been in this same container?

No they have been in these containers since germinating, there’s only 4 out of 18 this has happened to. I’ve upped the fish mix slightly and will keep an eye on them.

Up pot into some well cooked soil.
