Someone Help me with a P deficiency Please

[wekiee]

Hi i try treat a P deficiency in past 2 weeks my plants all got loads of yellow leaf and brown spots on it but buds starting growing and looks healthy

Today i feed them with:

Per each 5 gallon of water i put:

-60 ml of canna food
-20 ml of canna boost
-30 ml of pk 13/14
- 5 ml of acid


after check with my food tester it come to 16

then i ph test (i use drops
it come to 6.0 nice yellowish color

Do you guys think that is ok?

So hope that will help a lot the problem

i am in the end of the 1st week of flowering but during the last 2 weeks of veg i only give a water with ph and a bit of food due to a friend let me down and told me the problem was because i overfeed the plants


Ho

pe you guys Help me

That looks like N deficiency to me and your media looks very dry? during the last weeks of veg and first couple of weeks of flower your plants are using their peak nutrient requirements. Id say you have starved them when they needed it most or there is some underlying ph problem locking out N. I would start the nutes off slowly at half the recommended dose and slowly work up. make sure there is a little more N than the average flower nute provides and it may bring a little green back to those leaves. Just my 2c

That yellowing isn't P deficiency im pretty darn sure of it. Either way a feed will help.

P deficiency DOES NOT yellow like that.
