HELLO

I might need some edvise I' d say. My plants starts turning yellow and purple . I have prepered everything correctly:
-soillex mix 33% peat moss, 33% vermiculate, 33% perlite
-temperature at first was a little bit low 15 celcius (some curled leaves)-so i havent prepered everything ok but in fourth week goes to 23 celcius and stays.
-humidity 65%
-envirolite 6400k ,3500 lumens per plant
-after 3 weeks transplant them to 3 galon pots- less stress in the future- and use dilute fert 1/3 ( I use tree fern feed 26:6:11 with magnesium oxide soluble in water 1.6%,mg=1%.
-medium keeps water well, second watering after 8 days,used dilute fert 1/2 and stil no help
-water I use is soft tap water
The only thing I am concern about is the hydrated lime in my mix I made myself (Jorge Cervantes' tip in Bible) I couldnt have got a dolomite one at all. I put about 1/3 cup in 1 cub foot.
Ph of the medium is perfect 6.7.
Help me please.
