My very First Grow is in trouble...HELLPPP!!

Hello and good morning I hope that this post is not too lengthy but I am in dire need of help. I am a first time grower a true 1st time grower Working on my very 1st Grow. Pictured below is "Penelope" a Pineapple Express photoperiod, She is 8 weeks old vegging, and today is her very 1st day I flipped her over into flower 12-12 light cycle.
I thought everything was going fine until upon Closer inspection, I realize some strange markings on her fan leaves. (pic below) now nervous as hell... i don't want to lose her... we only have 7-8 weeks to go.
Stats:
1 - 5 Gal DWC (Kratky method, but now going to air disc and pump for all of flower)
2- 600w Mars Hyro LEDs (couple more plants.. not doing good either)
24"×48"×60" grow tent (tucked in a small wall in)
GH flora series last feeding 1 day ago.
1ml of micro... 1ml of grow... 1 ml of bloom... 2 ml of hydroguard & 2ml cal-mag...
Ph: 5.89... PPM 743 ... water temp 71.1
Humidity 40 - 60 %
Please help... all I can do is pay it foward as I learn best practices.

Yes, can.you see them?

I am not 100% on this one but am leaning towards a calcium deficiency. Ill attach a good pic for your future reference as well to go off of .

Thank you very much..

Bump your CalMag up to 4-5ml per gallon. Everything else looks good.

5.8ph hempy buckets (perlite/vermiculite) megacrop + 4ml calmagic

Future reference

So,.you were able to see the pics pretty good? ... and your pretty sure? ( I'm going to go with it .. i don't have any answers my self ...lol) so thank you for taking time to get back to me. and also since I'm going to add Cal Mag... then I'm just going to do a full nutrition change... im working with the FLORA series any suggestions and ... should my lights be about 18" for this first day of flower or go to 20- 24"?

I switched from 3 part GH series to megacrop and won't look back. 1 powder. 1 feed for veg. 1 feed for flower. It's much easier and a lot cheaper.

As far as lights go, I'd suggest getting a $20 Lux meter from Amazon. You want your lux in the 50k-60k range for flowering.

Excellent!!!! Thank you!!! I guess the more harvest i can bring to maturity the more confident and more skilled i will be... thanks again

and I'm going to Amazon now to order the "mega crop"

Just this week, as my gallon containers of GH are almost empty, I decided, based on the recommendation of another RIU grower to switch as well. I went with Jack's 5-12-26, Calcium Nitrate and MKP. Items should be in my post box this morning. I'm quite excited to dial it in in my experiment tents and be free of the shackles of over priced bottled nutrients.

Only took me eight years to focus my research and studies on nutrients, but better late than never.

I agree it needs cal mag

Agreed with calcium deficiency. It also appears to be very slight heat damage forming (sides of leaves curling upwards), but that diagnosis may be incorrect without more info.

I didn't see your temperature listed. What is it?

If you have too much cash and too much time, go with a multi-part nutrient line. If you're looking for cheap, dead simple and excellent results, Megacrop is the ticket. You're better off buying direct through Greenleaf:

No problem glad we could lend a hand to a fellow grower!
