How often should I add nutrients while flowering?

I'm 4.5 weeks into flowering and I'm starting to water my plants around every 2 days for the majority of them. Should I only feed them nutrients once a week or every other watering?
Thanks for the help!

Platinum OG Kush
FFOF soil
Botanicare nuts
400w hps

Mix the correct amount of nuts and feed every feed just dont over do ur plant looks very healthy nice buds

how many gallon pot are you using???? very nice plant!!!!

Once a week. Nice plant btw.

Wow.. Sweet plant! Nice work.

IMO they look very healthy excellent result, I look forward getting guidance and tips from you.

Thanks!! They are in 5 gallon buckets and this is our first ever grow! So far it's been good no major problems just some pm and 6 plants in our tent is a few too many but they are all looking good! Thanks again for the help!

Looks pretty damn frosty! Especially for only 4.5 weeks into flowering! I'm gonna have to put platinum OG on my to-grow list. I give nutes every watering at half the recommended dose personally.

Thanks! Og kush is only an 8 week flower which is nice but it's been moving along very quickly can't wait for harvest!

I give a little N every couple waterings...not much thou

This is another strain Ill be putting on my grow bucket-list.
I feed with every watering,just Bio Bizz bloom and cal mag though,but its worked for me.If you over feed youll soon know about it,same with under feeding,thats all part of the learning curve I suppose,learning to 'read' your plants.
Looking tip top though,well done!
