Flowering, but leaves are yellow and dying - Please help

[Jdog7000]

It looks like your plants need nitrogen.
If you stoppped giving them veg nutes they will use wht is stored in the leaves.
Either that or nutrient lockout do to a wrong ph.

That's N deficiency for sure.

What you are seeing is excessive, but some yellowing of lower leaves that far into flowering is normal.

Like JDog said they are now processing stored nutrients. The lower fan leaves are the reserve and their nutrients are being consumed as the plant focuses on reproduction.

Be careful not to overdo it on the N during flowering.

thanks, everyone. so i guess i will try a flush, but then after that should i keep using canna terra flores? or is there some other way to get the N levels back where they should be?

thanks!

I'm trying some fish emulsion 5-1-1. Hopefully it'll work...

Maybe the light is too close?
Is it burning the leaves?

[Opie Yutts]

I don't think it's a light problem because mostly the top leaves would be the problem area, or at least the top should look worse. This looks like lower leaves too.

what's the ph? looks like you have a ph prob to me. do you ad dolimite lime to the soil mix? an absolute must imo! the way the yellowing leaves have brown spots in them is one of the things that make me think it's ph issues. test the ph and post the results. without that info noone can make a definitive dx./rx. imo. keep us posted, i'm curious to see if my suspisions are correct.
