Advise needed on first grow

[Matto]

Hi All,
I need some advice on my grow please. I have 2 auto Mazar growing in a 2m x 2m x 80cm.
DWC system of 2 x 30cm pots and an 80lt reservoir. Mars hydro sp-250.
The girl on the left has had rust spots on the leaves from the beginning. I have tried multiple things but she stays the same. I LST the girl on the left. PH from 6.2 - 5.4 over seven days. I am using flora nutes and some various additives I get free samples of.

They are at 7 weeks

hmmm...well, me no plant doc fer sure, lol, but let'z see, off the top o' me stoned head, mebbe @Mañ'O'Green or @Arthur could help out ppp

Ok so it looks like a Cal-Mag issue but that can be deceiving. You are letting the PH get too low? I target 5.8 to 6.1 for DWC then if I slip a little it is not causing lock outs. The plants look a little hungry overall. Up the nutes the chart below is what I used when I ran GH. Ignore the PPM information it is GH's suggestion which is too high for DWC and autos.

The next concern is temp and humidity 78°F day 68°F night and keep humidity 40% - 60%.

Those are some bushy plants so make sure you have good air movement in the tent for flowering.

You should be using all of the products listed here in the amounts given. That said be sure to bump up the cal-mag by at least 50PPMs.

PS I have had plants that showed cal - mag like deficiency like yours and no matter what I did it never got better?

hey @mattey look like @Mañ'O'Green has you covered... by looking at the shape the leaves are taking you have a PH problem (that's one of the easiest ways to tell if there is a PH issue, the leaves start to twist)... my best advice follow what Mon O green has said and remove all the yellow / rusty damaged leaves so you will know if you have got on top of the problem... Like what Man O green has said get some air flow into the center of those plants, they will appreciated it loads. It will probably increase your yield as well... don't be scared and strip those ladys back, choose a line and tidy up the bottoms by removing all leaves and tiny branches (lolly popping)... make sure that if you are looking down on the plant that you can see down through it and see the pot then you know you getting full light penetration

if this persists then i would take this issue to the infirmary for the doc to have good look at

Thanks a lot for the advice. Spent some time defoliating good flush and Nute change. Used the chart above from @Mañ'O'Green thankyou. Arranged the tent a little better. I have flipped them now 12/12 and transition nute mix. They are at nearly 8 weeks now and I have a time constraint unfortunately.
Any other advice will be appreciated

OMG those are photoperiod plants. You will be skilled in the art of Super Cropping after this grow. Keep feeding veg nutes for the first two weeks after the flip. Growth is going to take off. you are going to be amazed.

Well that's gonna get real busy....
