First grow: Hello everyone

Hello everyone,

I've just started with my first grow and decided to join this forum as well.

I can say it has not been going well thus far, my first girl died shortly after sprouting, I was trying to transplant her and fractured her main stem. 2nd lady died at 2 weeks old, the LED lamp I was using wasn't powerful enough I believe, she stretched to much, the stem wasn't strong enough and just broke, tried reviving her without any success.

I'm now at my 3rd attempt, 3 weeks old today. It had all been going well for the first 2 weeks but now I'm noticing some problems. She has been showing some spectacular growth so far but for about a week and a half things have not been going well. Looks like growth has drastically slowed and her leafs are curling inward showing some yellow discoloration which eventually turns brown (lost 2 leafs already).
I have included some pictures to this post and some further info below, any assistance would be greatly appreciated.

Strain: Amnesia Haze Automatic
System: deep water culture in 10l of water (15l actual bucket capacity)
Lighting: 288W Greenception LED
Photo-cycle: 18hrs lights on
RH: 55-58%
Air temperature: 20.5C (lights on)
Water temperature: 18.9C (lights on)
Air pump attached to an air stone running 24/7.

Nutrients: Canna Aqua Vega A+B 20ml/10l | Canna Ryzotonic 20ml/10l | Cannazym 20ml/10l | Ca-Mag supplement 1ml/10l
Water: distilled water | initial Ph is 7 | initial EC 0.03 mS/cm
Starting Ph after nutrients are disolved: 4.5 | Ph up to 5.5 (organic solution), it drifts by itself to 6.2-6.3 within 10hrs at which time I Ph down to 5.7-5.8
EC: 1.00 mS/cm (right after nutrients are mixed in and water Ph is brought to an acceptable level)

DWC water is replaced weekly and I clean the bucket with distilled water before filling it in again with a fresh mixture. I'm checking the Ph and EC twice a day, 12hrs interval. I can clearly see the plant is feeding itself, EC is going down (-0.3mS/cm within 48hrs and Ph is going up) yet I don't understand why she is struggling.

Welcome Edvard, 2 things concern me. 1. Your water temp is pretty high, try to lower that somehow. 2. Your ph is starting too low, don't drop below 5.8 for now. Does your ph settle at 6.2-6.3 or does it continue climbing? If it settles at 6.3 just leave it there.

I've been struggling with the water temp, at one point it was up to 23C. Was thinking about dropping a couple of ice cubes inside the bucket.

If I don't adjust the Ph it keeps going up, highest it has been was 6.9.
 
Hey West Hippie, I'm feeding her Canna Aqua Veg A+B; Canna Ryzotonic; Cannazym and Ca-Mag supplement.
Is the water temperature that high you are supprised she was able to survive?
Water temp perfect, 66 f or 18.9 c can’t beat that ! No surprise for me these are some tuff plants to knock out ! I brought one back that spent a month in 30 f or 1.1 c .
Do you have some Z7 or hydroguard?

I could not find Hydroguard or Z7 in Europe, importing it from the US proves to be very expensive. I'm using local products like Canna and ice.

Does it work the same ? Are you able to flush that muck off the roots ? I’ll mix the hydroguard with phed water and flush through the basket ,you know it’s up in also !
