Hi UKAPS,
I really need your help to diagnose these plant deficiencies. I have some plants growing outdoors in direct sunlight. I use pressurized CO2 and EI dosing.
Here’s what I dose every week:
Sunday:
1.5ppm Ca
0.3ppm Mg
11ppm NO3
9ppm K (both from KNO3 and KH2PO4)
5ppm PO4
Monday:
0.37ppm Fe from Plantex CSM+B
0.28ppm Fe From DTPA 11%
11ppm NO3
7ppm K
Tuesday:
11ppm NO3
9ppm K (both from KNO3 and KH2PO4)
5ppm PO4
Wednesday:
0.37ppm Fe from Plantex CSM+B
0.28ppm Fe From DTPA 11%
11ppm NO3
7ppm K
Thursday:
11ppm NO3
9ppm K (both from KNO3 and KH2PO4)
5ppm PO4
Friday:
0.37ppm Fe from Plantex CSM+B
0.28ppm Fe From DTPA 11%
11ppm NO3
7ppm K
Saturday: 75% water change
I dose KNO3 everyday because if I don’t, I start getting stunting and the dying of lower leaves.
I’m wondering as well if I have a micro nutrient toxicity since I dose a lot of iron. However, new growth on all my plants looks fantastic, but it’s the older growth that is suffering. Some of the older growth even has GSA, but I’m hesitant to up the phosphate dosing from 5ppm 3x a week. I can’t increase CO2 higher as it would Then cause the fish to suffocate. As it is, I have the level on a borderline between what would make the fish gasp at the surface and what makes the fish not that stressed. I have no other algae besides GSA even in full sunlight.
Here is a lower leaf of ludwigia Rubin. All the lower leaves start to get these little patches forming in them, and they are translucent and delicate like tissue paper while the rest of the leaf is robust. This is especially an issue of my rotala.
This is a lower leaf of ludwigia arcuata. It has some holes in it, but that’s because the snails munch the parts that turn translucent.
Here’s another horrible looking leaf of ludwigia. The holes are from snails munching on it, but the edges almost started to disintegrate.
Note: I’ve only showed Ludwigia leaves since they are large enough for my phone to focus on. I tried doing the same with rotala leaves but the camera wouldn’t cooperate.
@ceg4048 I’ve seen a lot of your posts and advice and it’s helped me a lot in the past. Any insight you have into this would be greatly appreciated.
Thank you all in advance
