mixed garden mixed results

so i have a mix of plants SIS,diesel,strawberry,ak.. the SIS is growing like wildfire not one leaf is weak..yet all others are showing different things...they are all on same water supply. just cant figure what they need.....

first off i have hardwater 350ppm to start. was using canna, switched to gh hard water in the last 3 days to see if that would help
light 1000w
ph 6.0
temp 70-85
nutes- GH harwater

i dont get how some are doing so great but others arnt any help would be very welcomed

i know this would be much easier had i not mixed so many plants together but its what i had for clones at the time

anyone know these defeciencies? should i use epsom salt with hard water nutes?

Calcium, magnesium or iron deficiency. Assuming you are using hard water nutes, we can count out the Calcium. I would go with the epsom salts. No worries.

why is your water hard? what are the solutes............do you know? a water report will probably tell you. looks like mg def, but get that report, iffen ya can.

i grew the Strawberry and it was very mag hungry. it was very nice weed. its J.H. x Strawberry Cough x Skunk

thank you all i will get that test done asap....my water is over 300 ppm out of the hose so i figured it was hard. and ive never had these plants look like this till i moved...but your right a proper test will tell all
