yeah, wouldn'tn worry too much about first 1-2 sets of leaves looking a bit odd or wavy.
a fluctuating pH can cause such things -- varying rates of growth over time cause waviness. but, that's not the only cause. could be environmental too.
1.3 to 1.5 ec is a good place to start... well-balanced of course. i'd recommend a ratio somehwer near 7-8-15 ... slightly more resolved than 1-1-2. then adjust based on observations of plant. multiple brands do this and it is backed by science... jacks, southern ag, think even floraflex or athena's dry nutes are similar (one but not both, brain fart). Except that brand charges 10x too much for common commodities that are fertilizers.
5 bladed leaves look fine, eh? and those 7-bladed leaves popping out will llook fine too. ignore the singe and 3-bladed leaves as long as new growth is fine.
you'd be better at 6pH .. i don't get the 5.8 suggestion. just puts you really cose to a threshold of lockout for certain nutes.. probably why people have such common problems with calcium, lol.
p, ca, mg, and molybendum can all have issues under 6 ph. so you end up feeding extra of this to make up for it, but with just a slgihtly higher pH that excess isn't necessary to mitigate the lockout.
6-6,2 gives more room for error and virtually no ill effects. i doubt anyone has actually verified the things they say about this suggestion. i doubt you can see with your eye any difference in outcome between 5,8 and 6,2. just another confident statement born from a culture of groupthink.
