Try getting your ph up to 6.5-6.8.
That’s where it should be for the f farms.
And you’ve just started feeding so you should see an improvement going forward.
Just not too much at once.
I tend to feed on the lighter side so for me I’d go in at 850-900 ppm but I don’t use jacks.
Jacks has mag as part of their mix and that’s what I’m seeing on the leaves. A bit deficient.
Btw. The spotted leaves won’t recover.
Look to the new growth to green up.
Happy growing.

Aahhh. Gotcha. Ya. They do look a bit hungry tho.
You can bump up the in a bit more for your next feed.
Go for 700 ish ppm in and ph 6.8.
Give it a good amount of runoff to help wash out the imbalance in your root zone.
Should get things back on track for you.

We all had to start somewhere my friend.
They get better the more grows you do. 
Reading what the plant needs takes a bit of time to develop.
Good luck.

Full strength seed to harvest is 100% solid for Jacks.

even in ff soil?
Yep! I grow in FFOF sometimes.
i thought you were supposed to let ppm get below 1000

To my limited knowledge , yes. That is correct.
Most everything I’ve read here says to wait to feed with ff.
Folks started using jacks with coco and loved the growth and ease of use for the $.
For that then yes. You can Feed seed to harvest at full mix. Coco being inert.
But the ff being pre loaded and noted for being a bit hot out of the bag anyway you run the risk of an over feed on young tender roots imho.
