Over/under fed and your feeding too often, i grow hydro aswell doesnt mean they have to bathe in water.
You only feed when the top inch of soil is moist.
Their is signs of nutrient lock-out aswell EG the rusty patches on some leaves and discolouration of general fans.
Also your pots look a bit small.
Are you using a PH pen and Nutrient truncheon? or atleast something to measure your PPM/EC?

Not a hydro guy, but looks over fed and over watered... hopefully those that are more versed in hydro will pipe in for you... I am only begun looking into flood tables and DWC, but am not anywhere near pulling the trigger on that set up yet as I have a lot to learn... Check out the chart and see if it helps you...C__Data_Users_DefApps_Windows Phone_AppData_INTERNETEXPLORER_Temp_Saved Images_downloadfile-1.jpeg

your using clay ok haha sorry for not spotting that straight away.
how much are you feeding them 3 times per day?
And are you changing the resevoir atleast once per week?

I'm changing the Rez once a week about , and also i am using a ppm meter and a ph meter . The ppm is around 650 . 5.8 ph and in feeding 3 times during the night cycle . For about 20 minutes at a time . If it's a nut lock out how do I fit it , because I thought it could have been that so I flushed for about a week with clearx from botanic . And fresh water . This is my second time with a flood table , Iv been doing hydro for a few years now haven't had problems like this that bad before a few here and there but I fix it quite early before it got to this . So in quite confused and frustrated what this could be . I appreciate all input guys !

your PPM should be around 1400 at this stage.
Or attleast thats what i run in coco not sure if its different in clay. But 650 seems awfully low considering the pebbles dont really retain the feed.

You should get something to measure EC as PPM measurements arnt so accurate, things that come from your tapwater can put your PPM to around 450 naturall though thats some pretty harsh tapwater but its possible.
Electro conductivity will give you a better reading for how much feed your plants are receiving and after a while its easier to calc aswell.
It looks like your lacking nitrogen and phosphorus (DONT ADD MORE) just work on sorting out your feed routine first, how long have you been running that lower PPM?

What do you think I should switch the feed routine too ? And maybe a for the two weeks because after I flushed I cut it down pretty hard core . And alright I'll get one that does that .

well just increase it gradually, do you have a feed chart from the brand of nutrients you are using?
When i bought my nutrients from my local hydro store they gave me a feed chart for every weeks progress, my first grow i used the nutrients a little leaner than recommended so ididnt see the most rapid growth.
But now i know just how much i can push the plants before they will over-react.
2 weeks does sound like long enough for a plant that far into veg to start showing these signs, i recommend that you increase the feed to atleast 1100 (lets say PPM) at this point.
When you can measure EC you want the EC to be around 1.8-2.0 at this stage of growth, pretty sure mixing nutes (atleast the brand i have) at the strength mentioned on the bottle should give you the correct readings on the truncheon.

You're in veg 18/6 and feeding 3 times when the lights out, I don't do flood and drain but your feed schedule doesn't sound right. Flooding 3 times in 6 hours and none when the lights on 18 hrs?

Was sort of hoping he meant that hes feeding every 8 hours or so.

i would suggest you feed twice during lights on and once at lights out.
think of it this way, when your at the beach would you be happy with no water/drink for 18 hours and then just drink for 6 hours before bed?
or would you prefer to be properly hydrated throughout the day?
