2x plants 3x3 when to flip?

Hey guys just a couple of questions with my grow. Want to see everyone’s opinions. Got 2 plants in 5gal 70/30 coco/perlite they are in veg. Starting to fill out my tent. Wondering when should I flip them to flower?

First time growing in coco. Was a slow start in vegging but I think I’ve got my setup going well now.
When flowering how many fertigations a daily? What EC should I’d feed them?

Any input on my plants? Need anything? Also just got my new ph/ec meter

 

You mean The 2 carbon filters? Nah they are clean. They are exhaust fans I have 2 passive intakes. The fan on the left comes on when humidity gets to high. 1 on the right is just a constant exhaust turned down for fresh air.

 

Growing in a tin shed that’s not insulated in Australia’s summer/winter isn’t easy 40C heat in summer -3C in winter. Keeping humidity between %60-70 in veg Is ok now. But last year I struggled to get the humidity down past %60. This year I’ll be ready!!

(Right) 4” exhaust fan is on constantly with fresh air (speed controlled down)
(Left) 6” is on a humidity thermostat. Comes on %70 turns off %60. it barely comes on atm. But will in flowering I reckon.

 

Thanks mate. I only have a few photos underneath but they are hard to see. I’ll get better photos soon. I’m thinking I should of let them get a bit taller before I started LST so I had a little bit more room under the canopy.

The canopy is starting to fill out should I do anything to it?

I changed the dtw catch tubs from 16L under each plant to a 70L tub under both for when I flower. There are a lot of big fan leaves hanging down should I trim a few up?

After

 

Few photos today. Starting to fill out now.

 

I decided to flip mine today. I’ll be moving soon and plants may be a hassle plus they are very close I think. I just started maxibloom Lucas Formula with calmag, diamond nectar, Florablend, rapidstarter. I’ve got koolbloom liquid when is a good time to start it? And I’ve got a heap of huge fan leaves should I defoliate a few?
