The Mexican Airlines were the first ones to start flowering and the only change was from the Iguana Juice Grow to its Bloom version. It was given usually between 3 and 4ml per liter of RO water. Nirvana and sensizym as well were given sometimes at a full and sometimes at a half dose.
Now that flowering started it also started a real battle to keep the heat down. I realised that my exaust fan got damaged due to be sucking heat from them 2 600W, The guy at the hydro store said that actually many people come back with these issues and warranty doesn't cover it, even though the fan looks like a real jet engine, the whole thing in metal etc. According to him it would be more efficient (for the fan, not by the laws of physics) to push instead of pull the heat, but this also meant I would need 1 fan to cool the lamps and another one to use in the carbon scrubber, instead of using only 1 for both. So I was faced with the option to either buy a new fan or trying to use this damaged one until the end of the growth at least and then think about a solution. So I turned it around and eventually it started working faster (but not at its initial full power) when there wasn't so much hot air going through it anymore and for the carbon scrubber I used a small inline fan with hopes it will clean the whole place of smells.
By the way, the Moby Dicks and White Widows were moved under T5s to keep vegging for longer. It so happened that during the process I got them mixed up so I dont know which one is each now. Will have to wait until flower but already took 2 clones from one of them that had a real pure sativa look, with those very thin leaves (I believe it was a White Widow as the Moby Dick had somewhat fatter leaves. I got anyway different phenotypes of these strains going, so it will be variable and nice to compare).
