Yes, all pointed to a huge Phosphorus peak when i didn't do WC for maybe 3 weeks. i have nothing to measure it but from what i googled it had to be the issue.
after all help i had so far here i started to do 50% WC every day and went back to 60ML of all bottles of PMDD and EasyLife Profito.
Looks a bit better or at least i slowed it down the dying process. leaves seem better.
as i mention my other strong lights broke and i use a very weak one right now. so from what i understand, the plants consume less CO2 with lesser light?
maybe thats why it looks better too.
Im setting up a CO2 injection to my filter too now to add more CO2. just wait for the glue to dry....
I noticed that the stem of the plants and the older leaves, even the green, are turning blackish now thou? was that the effect of the NO2/NO3 peak? or something else?
