First time to flower, am I on the right track...

[newbbeginning]

So first time soil grow, seeds found in bags so strain unknown. In 13L pots in my wardrobe. 400W HPS lucagrow bulb, has been on 16-8 since I solved my teething issues.

Im pretty sure they are ready for flower, pics of both plants attached to make sure.

Have done some reading around and of Kodiaks guide to growing.

Questions about preflowering/flowering. In terms of what we do for plant care I have come across varying veiws so general consensus would be appreciated or for my chosen grow style.

Do I go straight to 12/12 and blacken off the room during the dark hours to prevent light leakage? or should I bring the light/dark ratios down over a couple of weeks say 13/11 then 12/12?

I have a guano based (Natures Own Super Bloom) nutrients, I have used the Vegetative growth only twice at 1/2 strength and water approx 750ml per plant every 3days. Should I feed during flowering or is it not so necessary? Can I feed too much of the flowering feeds since reduced N... and watering schedules should stay roughly the same or do the plants require more or less water during flowering?

Any feedback would be great!! and any other good articles on flowering/preflowering etc would be welcomed.

Thanks!!!!

Straight to 12 12 and if your room isn't light proof you will have hermaphrodite/growth issues. Prepare for the stretch too, those will at least double in height.

Go straight to 12/12. Don't dick around with the lighting.

If you have a good fertilizer that has a low N, and a high P & K then use it during flowering. Nitrogen is ok to feed tot your plants during the first month of flowering, but then you need to cut it out and feed only P and K.

Buy a TDS meter that checks the total dissolved solids in the water/ferts you feed.
Stay low at first and then work your way up.
When flowering the plants will become root-bound and need more frequent waterings/feedings.

If you are new to this then feed, water, feed, etc.
