so many pics, they look ok though. the first 2 look like maybe a recessive trait, i would say the same as sub about a little water and light burn on those white spots and the rest looks like you need cal-mag...just fuckin with you sub. keep an eye on the pale leaves and keep checking the pics in the book if the leaves get worse. sometimes you cant make the match until your leaves look as bad as the ones in the book.
mildew smell in the cubes. you know you have the right wet/dry cycle when they get dry enough to get rid of that smell. you can let those cubes get very dry before the clone will wilt....but there is a fine line between too dry and just right. i went through everything you are going through with the dome. thats why i try to remove it as soon as i can now. i came to learn that the longer i kept the dome on, the harder it was to get them to not wilt when i took it off, also they rooted faster because they were able to dry out. the mildew smell usually started after a week so with the dome on, i try never to keep the dome on for longer than about 5 days.
ive never even heard of that nute. most everyone i know uses either GH or house and garden. i would say stick with whatever nute the guy helping you uses. reading what sub just wrote to you about LK sounds all too familiar. about a year ago i spent hours upon hours teaching a buddy of mine how to grow. he copied my setup to a t except for the nutes and went with 3G. he called me every night for the first 4 weeks asking me why his plants looked so bad with this 3G and my response was "ive never used it so i have no idea". he changed to GH and has had a better yield than me the last 2 runs...fucker.
this is why my first advise to you was follow subs directions. if you are going to switch nutes make sure you know somebody that uses it and that that person will help you when you need it. or stick with ionic until you know more about growing and can take on a change like that on your own.
...my 2 cents anyway...
keep up the good work.:thumbsup:
