Help. Yellowing veins, roots slightly browning.

Hi need some help. This might not be anything but im concerned for my two small plants and would love any input!

Two weeks old, put them in dwc a week ago. 4x4x4cm rockwooln cubes surrounded by clay pebbles(hydroton?) in 8cm diameter containers, 20L buckets. EC 0.25 with a PH of 5.9 and 6.1 on the other. I use hydroguard aswell. Temp is about 22-23 celcius and prob about the same for reservoirs(i dont have a way of measuring it and dont have chillers). Water lvl is 5-8 cm below pots. I never water them from top cause my airstone bubbles reach all the way to my lids.

What is causing the vein yellowing and some very slight browning of the roots on one this one? Some leaves also seem a bit flat and twist. I noticed that the water is barely reaching the lid on this one as the water dropped a bit. Ill top that up again.



This one is tipping over a bit but stem is straight and "stiff". What can cause this? The first small round leaves are really yellowing, is this bad? Roots seems fine though. Reason they are smaller is i had some problems transplanting.

Seeing it everywhere right now. CALCIUM. Your root growth is nice but they need calcium for stem strength, overall growth, and building chlorophyll.
That second one looks like she is reaching for the light.

I would also reccomend getting rid of the paper covering your plant's base. Those don't stop light and just provide a wonderfully moist stagnant environment for mold.

I have calmag but didnt add it cause i thought it might be overkill as my tapwater is 0.07 EC and my nutrients are made for soft water. Am i thinking about it wrong? Il add some then thx for the tip

Second one, the one with a yellow leaf? How can u tell? I struggle to tell if its to close or far away.

Its gardening plastic, white on one side black on the other. It does block out the light but should i remove it anyways?

Again, thx for the input im all ears

Just be sure it has air flow

Fan blowing straight over them, almost on them small beauties. And also airpumps in the buckets make sure there is air passing though on the way up : )
