How long does it take to clear phosphorus deficiency

Howdy all! Im having some phosphorus deficiency, and was just wondering how long it takes to clear up? I have her some tiger bloom at half strength (just started flowering about 12 days ago). Do the leaves ever get greener after they turned yellowish, when the problem is corrected? In the second pic the leaf is a yellowish color

Got pics?
Leaves will get greener if you've got a deficiency in a mobile nutrient like Nitrogen or magnesium. If the deficiency is caused by a non-mobile like calcium, the damage cannot be reversed -- but new growth should look fine after making the correction.

Ive been giving her a good amount of cal/mag because i was having some mag def, about a week ago, which i think i corrected the problem. Im guessing i have P def because of the symptoms i now have (pics now included)

Thanks for the reply!

minutes- with foliar feeding. but if you're using a complete nutrient system how could adding more help?

Glad I could help.
From the pics, it looks like you had a mag deficiency, which is very common.
There are better options than Tiger Bloom, but it will work.
Contrary to popular belief, you can use the same nutrients from veg all the way thru flower.
Best bang for the buck right now is Mega Crop. They are running a promo and you can get a free sample for the price of shipping. I got 230g for $2.61

Thanks again! Ill definitely pick some up, cant beat that price!

How do you know you had a P problem? looks like P but you don't state what PH your running at, look closely at a deficiency table, looks like a PH problem to me but that's my 2 cents worth
