Day 1 : Well lower left is the best. Chronic is growing like crazy. The others? WEll gorilla is not doing well. Last week so I suspected magnesium too much 2g /l. So I tried diluting a few times. Still same. Suffering. Then I tried today lifting a bit the lamp. See if its about too low light since passed to 600 w. And I changed the water put the old last week too high EC water and added distilled water. also checked if its temperature problem since 600 w (too hot) so opened window.
Day 2 : result : it was not temperature, it was not too close light, and the distilled water and last week water didn't help. So today I purged as much as I can the tank and replaced with pure distilled water 15 liters and waited. After a few hours still suffered. No change. Yeah.
So I put Bio grow 1ml, Bio bloom 3ml, Topmax 1ml. No bio heaven and no magnesium salts.
Day 3 : gorilla still not better. The EC lowered like 0.8. later I will check again and put bio heaven this time for the others. And yeah I think gorilla is not hermaphrodite. oh yeah. But still Gorilla maybe dying after all.
