first grow diesel ryder and auto pounder problem

this is my first auto hydro grow, i am doing two dwc buckets with a 400w mh. my diesel ryder is growing great but my auto pounders stem is white and looks fragile and the plant has started to lean over. is it a lost cause or can it be saved? the humidity in my room is hard to control and drop to 20% at times, could this be the problem?

the jiffy pellets should be coverd by the clays #1 are roots in water #2 air in water working good #3 water temps in the 60s #4whats the ppms of water with and without nutes #5whats the ph now #6 what is the temp at top of plant, and yes it looks like it can be saved

i am top feeding still, roots have not touched water. i have not added nutes, i was going to wait atleast another week. it is 1 week tomorrow from sprouut. the water temp is 65 and air temp 84. ph is 5.8-6

feel bucket with water up to just below the top of clay so it keeps wet have the air on and give it like 50 ppms air could come down to76 other then that water temp and ph is good

Thanks a lot man ill give it a try

You dont want the rockwool to stay wet. Raise water level til bubbles are hitting bottom part of basket. If you top feed, water to the sides of cubes and not directly on them.

what im trying to say if not comeing across is go to dwc do not top feed any more but have the water close enough that the pucks do not dry out im guessing its pucks that you started your plant in the roots should be at the bottom of the puck by now and start to take a little food and it will grow like crazy im asuming you have been top feeding a few times a day because i see no drip system that young of a plant needs there roots moist at a times im guessing they get a little to dry before next watering do to the heat and light and no dome thats why im saying go to the dwc now. hope this helps and you under stand what im saying

auto pounder didn't make it. how does the diesel ryder look? its a week from sprout and looks a little small to me. any feedback would be appreciated.

Any ideas on why my leaves are starting to sag?. I added nutes yesterday at 1/4 on day 8.

Any help? The leaves are getting worse.

What are those things they are planted in? Rock wool?

yes rockwool plugs
