 Now Flowering - Lucas Formula? GH Flora Series help! - Possible nute def/burn pics too!!!

today is day 7 of flowering, and im going to change the nutrient solution in my DWCs. im using GH's Flora Series, and i'm getting what looks like both nutrient burn on newer leaf tips, and what looks like nutrient deficiencies in lower older leaves and mid level somewhat newer leaves. it looks like cal/mag issues, but im not sure. i use calimagic, so idk...

newer leaves:  older leaves: 
TNT Kush
  
i ran across the Lucas Formula, which just uses flora micro and bloom, and cuts out the gro altogether. apparently if you use it his ratio (8ml micro / 16 ml bloom = 1 gallon) it contains enough nitrogen for the plant that you dont need flora gro. this sounds good to me, but i have no idea what im doing really. this is my second grow, and first time with hydro.
has anyone used the lucas formula? i'm not quite sure what to start feeding them at this point. i wanted to consult with the growery before i make a new batch of solution. i know some of you use, or have used this line of nutrients.
heres a few pictures of my plants. they are both 46 days old today, and on the 7th day of flowering.
(i know theres a doctors diagnosis page but just wanted to make one post instead of 2)
thanks!

dont say diseased! just say, lacking nutrients or something. diseased sounds so hopeless lol

Looking good, apart from the diseased leaves... but I guess this thread will soon be moved into Doctor's Diagnose.
First question there could be: How old are they and did you flush them already 
like i said in the post, they're 46 days old.
i've flushed a couple times but not in the past week or 2. i dont think thats much of a problem.
i dont know what to do about the nutrients!

yea, ive been using the flora series from the beginning.
i needed to switch the solution out, so i just went by the lucas formula for 2.5 gallons of water. 20mL micro and 40mL of bloom. did that to both plants. hopefully i dont kill them!
i dont have an EC or PPM meter. just a pH meter.

i use RO so im guessing its as close to 0ppm that i can get
so far i havent seen any negative reactions from the plants. im sure it'll probably take a few hours to show if anything is wrong
