Need help?whats wrong?

my 6 little girls are just about to end there 3 week of veg. growth and they're not looking as good as they should. Some leaves are wrinkled and the ridges are very defined, you can clearly see the bumps on the leaves, i think that was a zinc deficiency and the ph was high, i changed the nute solution last week and the ridges seem to be going away but know some of the leaves have a yellowish brown to them, and some of the older green leaves are a little yellow and it doesnt seem to be getting greener i really have no idea, i think it might be nute burn, or a lack of nutes? SOMEONE HELP! i want my ladies to be ok, there still seems to be a lot of growth, and the new sets of leaves look very healthy, maybe a little small though but maybe thats just strain


nutes im using:
Resevoir: 40L
i also have a 1L spray bottle with 1-2 ml of liquid karma that i mist them with once every other day or so

temp: 73-85
humidity: 50%-65% sometimes 40% i try to drop it down using water in dishes
they get fed 3 times a day for 15 mins
co2 6 times a day 15 mins

iguana juice grow--- 52ml
sensizym---115 ml

Piranha, Tarantula, and voodoo juice i skipped this week, cuz thats what the AN calculator says

organic B---75 ml
cal mag---30ml
liquid karma---70-80ml i cant remember exact amount i put in this week, it was less then the previous weeks though

any way heres pics help my girls
if you need more info please ask

ive been doing some research and maybe im not giving it enough nutes, for example the iguana juice bottle says 3.5ml/L which means i would have to give it around 140ml per week instead of 52ml, not sure though, still no answer from anyone
