Please help girls sick and dying

We are growing indoors in clay balls, with a recirculating system running top feeds into 17 LTR buckets that are draining into to 70 LTR tanks. The watering schedule was watering every hour for 15 min but have reduced it to every two hours with the problems we have. We have 3 x 400watts going at the moment. The strain is super skunk. They are in week two of the veg cycle.

I'm pretty sure i know where i fucked up when i transplanted them into the veg tent i feed them to much and gave them nute burn and now have nute lock out, to counter this i reduced the nutes in the tanks by half and added DR Repair which is a Urea, iron based repair feed with 3% Urea Nitrogen and 0.6% Chelated Iron and is spouse to counter nute problems. This did not help so have started to flush with straight PDed water and have been doing this for a day now but they are still getting worse. They started off with yellow leaves appearing on the bottom of the plants but as it has gotten worse the yellowing is now creeping up the plants towards the new growth.

Sorry do not have any photos at the moment but will include ASAP.

What other measures can i take to dealt with the over feeding?

Is just straight flushing going to be enough?

Also we have have had very high temps recently where i live some times in the mid 30 deg c.

REALLY NEED HELP WITH THIS ONE PLEASE!!!!!!!!!!!

give them a real good flush for a couple days. you might lose some of the lower parts but that dont matter as you normally take the bottoms out the plant for flower. the new growth should look good let the plant get healthy again and then start with your feeding at a lower dose. if your having heat probs drop a light of for veg will help with the heat but without pics or a better explaination about your grow conditions plant numbers ect cant help no further.

Sounds like nute burn.I'm in hydro E & F expanded clay.I flood the table 3x for 15min in 24hrs.
Don't look at the yellow and burned leaves look at the new growth.
Use water untill plants recover then start with about 1/3 recomended nutes and work your way up.

Things happen fast in hydro you gotta be carefull with nutes start 1/2 strenght and work up.
I never go by the bottles it's always to hot.

Hey bro, ya been there. What you have done is fine, I would not add anything just balanced distilled water. Leaves will still burn or die because it was to late for them. Check the new growth to see if the problem has stopped. I just burned my biggest one and it has been like 9 days just sitting there, She is just now gettin her grow on.

we have have had very high temps recently where i live some times in the mid 30 deg c.

That will burn,stress and stunt the plants bro and is the cause of your problems, are you serious its 35 in the grow room?

Hi

Thanks heaps for you replies.

Still watering every two hours for 15 min, with straight PHed water. Haven't seen much movement in the tanks the PH swung a little which hopefully means they are taking on some of the water but the level of the tanks haven't really dropped at all.

Here are some pic of the set up



We are running with 20 plants in the veg tent on a recirculating system running top feeds into 17 LTR buckets that are draining into to 70 LTR tanks.

Here are some pic of the girls. The first three were taken yesterday and the last three today





And these last three are shots of the girls from the top (taken today also, all the pics are of the same three girls).



Please excuse the pics had to take them with my phone as my camera is not working.

About the temps, yea unfortunatly am serious the veg tent is in our garage as we have no room inside and it is a 10 m x 3m brick garage that is only 2.4 m high with tin roofs, so as you can expect it heats up like a mother f#@ker and we are all ready on our power limit as we don't bypass. We are in the process of installing intake/outtake for the whole garage but when its 40 deg c outside this don't help much.

Any thoughts on this would be much appreciated.
