Leaves browning up and dying from bottom during flowering

Hello everyone. First time grower here. I am currently in week 3 of flower. I have been using 7 gallon smart pots outside and using the sun for light on a 12/12 schedule (I move the smart pot into a shed for the dark period). I am growing in fox farm ocean forest mixed with natural soil from the ground. 75% FFOF/ 25% Ground mix. The only nutrient I have been using is Dr. Earth's Golden Bloom (2-7-2) during flower and have followed the instructions which require a feeding every 2 weeks. I first noticed the problem at the beginning of this week. A couple of leaves started to yellow, then the bigger fan leaves did the same all on the bottom. I have been watering every 2 days since the temps have been a little high for SoCal. Watering with tap water that goes through a filter and left out a day before watering. I have not changed anything since I went over to flowering. What do you all think? Thank you for any help I can get and allowing me to be a part of this forum.

FFOF usually has enough nutes to carry a plant at this stage ( works for me ). Its the
" GROUND SOIL " that is confusing me , why cut fox farm with outside dirt ?

Ffof usually only needs perlite and nothing else. I use Dr. Earth Liquid solution ( 3/3/3 ) for mid flower with HYDROPLEX . Are you Ph water ?

Make sure you are Ph at least 6.3-6.5 in water and feed.
Plant looks pretty good otherwise. ( green )
You are probably locking out a little but .... Your flowering plant WILL FADE LEAVES as it pulls nutes from the leaves.

I would add FFOF as top dressing on top of pot and water in with a teaspoon of calmag.
 
I am going to admit that I have not been checking the PH. I will be going today to get a meter and start using it right away. I used some of the ground soil in an attempt to gain some of the nutrients within it. I know now not to use it. I got some calmag and will be topping off using FFOF tomorrow after I PH my water. Should I try using Dr. Earth Liquid solution and Hydroplex at this stage instead of the Golden bloom? Thank you for the replies.

What would be the best purchase as far as quality goes? I have no experience with nutrients, I just go by the reviews.
There is no unanimous "best". There's different opinions per grower but any of the nutrient lines you see in general would be fine.

I think the plants healthy because its showing it needs some N .but its normal for a cannabis plant in its life cycle to consume itself if there isn't enough nutrients available .or if its already far in bud .It still likes a little N in flower PK helps it ripen up Phosphorus helps with budding try a little molasses

your plants look good. plants use up leaves and they die especially in flower usually it will be the lowest leaves. I see no deficiency. for leaves that yellow if it were nitrogen more leaves would be yellowing.
 
Its not a big deal... Its called light... It shines down or even side to side on a plant. The lower ones die as the top takes the sugars from the bottom... Its not a big deal. Some strains do it more than others. I usually just cut those away or pluck em as they begin to shrivel up
 
Update: I have been checking PH now and making sure it is between 6.3-6.5. I fed just today with Golden bloom and CalMag and here are some pictures. I have noticed that they are getting small holes within the center of some of the fan leaves (shown on the last picture).

Another update: Some of the smaller buds are fattening up now. I am willing to be very patient for results! Hopefully I am at the end of the road soon. What do you all think? I have been feeding a little more and am at the full dose that the bloom nutrients bottle says to give per week. This is week 6.
