Start using it now on the plants in the picture.

The next time you start new seeds don't give them anything for 2 weeks. They will live off their cotyledons. Then start with low dose nutrients. Start giving cal/mag at 5 ml/gallon when they are 4-5 weeks old.

The last part about the ph..

I am saying that a runoff ph of 5.5 in a small pot can be fixed just by not lowing your tap water ph for a time or two. You don't need to start doing a bunch of stuff and end up overcompensating. Your plants are fine right now.

You need to figure out why they are not flowering. Just let them under 12/12 and see what happens.

You could not do anything right now. No cal/mag. Just your normal watering and fertilizer. They don't have anything wrong nutritionally that is keeping them from flowering.

Keep them on 12/12 and see how long it takes for them to flower.

Did you check your timer and make sure the lights are 12/12? Did you check for bad light leaks?

Are you letting the pots dry some and breathe between waters? Basically asking if you are watering them too much.

But like I said before. The deficiency is not keeping them from flower. Keep them on 12/12 until they die or flower. You need to see when they flower. They have to flower eventually.

Stay the course. Give some cal/mag and update us now and then.

Do you even see any preflowers at the 5-7 internodes?

hi..
about cal/mag:

Can use it with tap water? then I correct the ph ..
I always use it or alternating with water?
I can mix it with other nutrients?
which cal / mag advise me?

plants have preflowers but remain small and do not grow!

thanks
Ca/Mg is not always necessary when using tap water, nor does it usually cause problems. Good nutes contain enough Ca/Mg for most applications when using good tap water. However, cannabis can sometimes use more than available and/or tap water is low on micronutes. Usually Mg not Ca.

I use botanacaire and/or GH. Both can be added to any good nute.

I'm not sure about the flowering issue. I'd need more info.
