Ok one has gone purple the other hasnt :)
Iโm still of the opinion thatโs itโs too much calcium , maybe due to the microbes improving the circulation, next change tomorrow with out any cal mag we see what happens ๐ค
Changed reservoir Thursday - Boxing Day
Had a few issues with calcium with this strain , it first appeared two weeks ago , I m of the opinion that maybe the concentration got too high locking ou5 the nutrients , ph is perfect at 6.3 but still later on we are seeing it in the other plant , this could also be the boxes , as this is the first run with them we can see if itโs going to happen with the northern lights ๐ค
Big one is trying to go purple , the gold in her leaves is quite amazing , a side product of too much calcium I think
