Hi,
On my Nano that I dry started (see signature), the new leaves of P. Helferi were white. They looked healthy though and didn't bother at first. Now, I notice that those white leaves tend to show on the long term signs of weakness/transparency
Not all plants are affected, but mainly those exposed the most to light. Increasing my TPN dosing and decreasing lights reduced the problem but is still here:
Things started this way, end November, all new leaves once immersed were white, with green nerves:
Now, some are still looking this way:
I dose 1.5ml TPN 3x/week on my 12gal/45L (7gal/26L real volume)
Also, just discovered that I have probably some stones adding GH and Kh to my water as I ended up with GH 8 and KH 5 (source water is GH 5 an KH 2)
Do you think with my EI dosing that it could be iron deficiency? It would be strange as I'm really low light (0.9W/gal or 1.5W/gal if real volume is considered).
CO2 is really constant, mist, nice color on drop checker, no algae and good flow on all parts including the bottom (P. Helferi leaves moving). Measuring Fe with two kits gives me a 0 ppm concentration (wehere my 60gal shows 0.1ppm with same kits)
Also, I had a BGA bloom on start, so could it be Nitrate deficiency on start?
Now, many leaves are getting back to a green color progressively
Many thanks for your help
