I have a lot of option here to look at, nitrogen, new plants, fertilizer routine. so i did verify every one of them.
The longest one was to verify with test kits, in the morning before adding micro and macro fertilizer, then after adding some, and at they end of the day, thats after the light turn off. Just to see if everything go as plans D it for a as long as needed. Now im adding 1ml of macro instead of 6 ml (normal dosage for pps-pro) and 3 ml for macro instead of 6ml. Its freacking me out.
After lots off debate, and trying to find a solution from your opinion. I found out what it is, its calcium deficiency. yep its simple as that. weird right? My shrimps never had calcium for them so i added some. Fix the plants in the same time. pfff that's was weird right? usually, it happen only is plants are twisting. a well, good to know for others
