Curled wavy ripply and droppy leaves! Please help! DWC

Set up:
250w HPS
5g DWC bucket w/ airstone at 3.6lpm
4" can fan
(set up to pull air out of the room through the light and exausts into a Carbon filter in the attic.)
20" Oscilating fan on high at plant level
BC Boost, Grow, and Bloom nutes
Organic pest control - Derived from deluted neem oil. (Light mist every other week)

Conditions:
16/8 Lighting
Light 10" from plant top
Aprox 75 degrees during the day at 60%RH
Aprox 70 degrees at night 50%RH
Water temp runs between 77 and 74
PH: 5.8
PPM: 700

Plant:
1 Ganga Dwarf Low Rider
25 Days old
I change water about every 7 days, keeping the level 2" below net pot.
Roots are nice and white, some light brown tint staining on older roots, no odd smells or slime.
5 set of leaves coming in.

Problem:
Leaves are droopy and the top set is ripply (wavy looking) with the tips and edges beginning to curl up. Upper sets are darker green then lower but everything is green. There is a very minimal amount of nute burn on the tips of the 2 and second set of leaves, no heat burn on any of the leaves.

I suspected overwatering originally. Used to mist about twice a day, I am not misting at all anymore.
48 hours later still the same problem.

Next I suspected over fert so I flushed with fresh water for 48 hours. Little to no improvment so I went back to a 450PPM solution of boost and grow.

Finally I thought Light intenisty stress so I moved the light from 10" above to 20".
Minor improvments but obviously havnt solved the problem.

Could it be because of my res temp?

Should I be using Ice bottles?

Should I be using H2o2?

Could It be because it wants flowing nutrients being an autoflowing plant? Its almost a month old.

Any other ideas?

Ok without pics its hard to tell. But if you believe its overwatering and it kindo of sounds like it, Then i would lower the water level in the bucket. Let the roots get more oxygen to them. See what happens after a week or so. Hope this helps, Lamp.

Updated the main post with some new info... Still looking for answers!

pics would help. are you using rockwool or hydroton as your medium? if it is rockwool, than very impt to not let that rockwool get wet-no top feeding either. sounds like you have eveything chimed in. and changing res every 7 days may be excessive. tons of bene microbes that build up in there and get flushed each time. I would go with once evry 2 weeks and top off your res as needed with water and nutes to maintain your ppms.

wavy and ripply leaves signify either overfert or a ca deficiency but rare if young.

Half strength nutes per the back of my nute bottle brings me to about 450 so it seems funny to be over fert but maybe?

Seed germed in 1" rock wool then put in hydrotron as soon as soon as it sprouted.

Ill quit with any kind of top feeding and maybe add in some water to delute my PPM to something closer to 250-300 and see what happens.

I must say I have seen a TON of root growth over the past week.

Thanks for your input any other ideas are appriciated. Ill work on getting some pictures.

ok, I reread your post-didnt see you had 700 ppms listed. I would say that may have been excessive if they are under 4-5 weeks old. will take a few days to show improvement from being over fert. I would leave em at 450 ppms as you have them.
the res temps seems a bit on the warmer side but nothing out of range. I would however try to lower it to 70 or below- I keep mine at 60. as far the the h202, dont see a need, will kill off good and bad bene's. botanicare makes a great res additive of many bene microbes-smells real bad. let me get the name for you.

roots come first, than above ground growth so you are where u should be.

How do you chill your res? Aquarium water chiller?

do they sell aquarime water chillers? the best and most cost and effecient way is to have a fan blowing over the top of the res-will lower temps up to 10 degrees. used to make 'nute ice cubes' in the past when temps were an issue. frozen water bottles suck.instead of changnign ur res., try topping off with cold water every few days helps as well.

Ill give running a fan dedicated to cooling the res a shot. Thanks for the feedback.

Yeah for 200 bucks you can get an aquarium chiller but its alot of money and work to hook it all up. Should work well tho.
