Yellowing leaves?

Plants started week 5 of flower today, I’ve noticed some of the leaves yellowing now.

Is this too early and are they deficiencies I should be worried about? or just normal for the plants age?

New grower so any help is appreciated.

What you feeding them? Bloom or veg nutes?

It varies on strain but some prefer more N than others. It’s quite frequent that most bloom fertilisers have too little N and therefore it’s ‘common’ to see yellowing lower leaves.

If you’re feeding and have the option give her 50/50 grow and bloom for a couple weeks then move to bloom for last few

Actually I’ve just looked again. 1st pic is signs of calcium def, 2nd magnesium. Others are N.

So you’re lacking N, Ca and Mag. Luckily there’s a product just for you!

Most calmag supplements are made from calcium nitrate, this gives a source of nitrogen as well as cal/mag. Also a little iron too which is never a bad thing in flower.

Just go easy with it - can screw a grow up real fast if too much is used.

Firstly what's your medium? What water are you using?
Most nutrients come very balanced with cal/mag these days and personally I have never needed to add extra.
Trying to mitigate the problem by adding more of something could have detrimental affects if you already had sufficient amount of said element in the first place. It could be as simple as the wrong pH or salt build up not allowing your plant to take up those nutrients.
