Using distilled water 0 ppm with no calmag is this my issue ?

2 tbs micro 4 tbs bloom per 5 gallons.... ppm should come out around 570 in pure water

lucas formula should be used around 8ml micro 16ml bloom per gallon

hmm

that's weird
it does look like calcium and magnesium def but
you really shouldnt be having the need for calcium or magnesiun additions with that mix

theres plenty of both the way your mixing it

are they in bloom yet?

does the ppm/EC rise or fall over time?

does the ph rise over time and if so how fast

it might be time to give them 0-6-12

when was the last time you changed your buckets with fresh nutes/ph'd water?

your mag levels look good to me and with 8ml of micro per gallon @5% calcium ...u should be fine on calcium. Change buckets if its been a month, if not, you might want to still do it to rule that out. After that Ide trim those sun leaves and let it be for a bit, all your new growth looks good.

I wouldn't trim the leaves. Getting rid of them doesn't get rid of the problem and is just mutilating your plants for no reason.

Agreed, if you have not switched out the water and nutes yet and a rez rinse, I would do it now.
I keep my ph levels at 5.5 to 6.0 with the nutes.
Also what shape are your roots in? They should be white (or tan because of GH nutes), and free from any slime etc.

I think the wait and see approach is also a good way to go

changing out your nutes if theyre would would be a good thing

the only other option is to watch your reservoir ppm and ph to see if ppm goes down and ph goes up then you could determine if you should feed more or not

if the ppm climbs and the ph doesn't then you could also be over feeding

so wait a few days and log your reservoir info to make a determination
