HydroHeart Grow How does this look?

This is about 25 days in the Hydroheart. How do they look?About to switch to 12/12 after A flush.

Welcome to RIU! your plants look pretty good, you have a but of leaf curl going on. it looks like they might have a little heat stress. what nutes are you using? pH? what are your temps and humidity? what kind of lighting are you using? how much vertical space do you have? those are going to double in height during flowering

that hydro system is pretty cool, how do you like it?

The leaf curl started when I did a fresh veg nute change with bushmaster in it 2 days ago. I dosed the pump res with Bushmaster and some Magcal 2nd day for the bushmaster nute cycle. Im using Technaflora Recipe for Success. Ph has been 5.2- 6.8 with fresh nute flush every few days.I have a live ph and ec meter going. Raised ppm from 250 to 500 pmm scale .5 and ec from .3 - .75. I think I have about 12 more inch's of hight left. Temp in the day is 75-85 humidity 25-50 %. Temp at night no lower than 65 humidity 25-55%. Co2 on during the light hours.I have a 400 watt Eye in there. There are some issues with the system. This has caused some slow growth and bad health for the plants. One problem is the hydron balls get stuck and cause pots to overfill. The fix I think will be using Sure to Grow medium. Next problem is screens that came with it to help stop the hydron from blocking the tubes. I think it would have been better if i did not use the screens. The screens cause a slow flow problem if the block the inlet and outlet holes. I fixed that by cut holes in the screens so it did not block the inlet and outlets of the pot. Problem I have now it the roots are in tangled in the screen and causing a slow flow problem. Im trying to fix this by super airtion of the system and turning the pump on for only 15 minutes per hour. When the pump is off the pots will even out in about 5 minutes. When the pump comes on it takes about 10 minutes before the fill switch is made in short hits. This short hit on the fill pump will cause the pots to overfill. I have 7 watt air pump that will be going into the system. The unit holds in the pot and pump res about 3 gallons of water. This little amount of water has me thinking its better to flush the system with fresh nutes every few days. To keep the ppm in place I have been adding a x7 per gal veg nute dose at about 4 oz while keep a low nute ppm water in the rez. I been using distilled water only. I also installed a h50 cpu cooler to low the water temp.It works ok drops water temp about 4 degrees. The light leaks where all over the unit. I took the time and re sealed the unit with foam tape on the doors. Now it has no light leaks on the doors. I like do like this system but There are some problems that have to be worked out.

How does that sound?

Here are more pics

Do they look like there is something wrong or are they looking good????????

anyone there?

the leaf curl isnt too bad, just a sign of a potential problem. your temps are fine as long as you have the co2 dialed in. it may be from pH fluctuation in your small res. only other thing i can think of right now is maybe your roots aren't getting enough oxygen.

another thought, you are using distilled water do you add a Magnesium supplement to your res?

I use magical at first using at 1/4 dose now at a 1/2 dose.

i have 4 watt air pump. im going change it to a 7 watt in a few days.

Oxygen deficentcy, check your water levels ( my guess is they are high) , also a bigger air pump couldnt hurt.
