First Grow, 2 Northern Lights, weeks 1-6

week 1, got cuttings of 2 NL, in Rockwool, planted into bio soil, fed with water

I was using 400w HPS in week 1-3, I then switched to 400w with boost week 4-5, cutting it short by 36 hr for a long dark cycle, coming back on with 600w HPS with blue 12/12

lights on 27 deg C, good ventilation
lights off 22 deg C, good ventilation

week 2, was advised my tap ph would be fine in the soil I was using, I never had any method of testing ph for week 1-4, by time week 4 nutes increase ph had dropped very low, also 1 feed of over nutes left her burnt pretty bad, very dark green leaves so I got worried and flushed for 2 feeds with ph balanced water, then started feed cycle again using ph up to get it within 6-7, runoff ph 6, she bloomed very nice with some LST was very low and bushy

So for week 5 going into start of 6 being on 12/12 under 600 HPS, the 2 plants have shot up and been lolly popped, they look to have 12-17 main heads coming off either plant, this I my first grow and I just got a bit carried away trying to optimize light over the whole plant.

P.S I am feeding with canna terra vega (veg), terra flores (flowering), boost. no PK this time round but maybe next time

so that's it current and up to date, this is the point where I hope people are gonna go wow how many heads your gonna get ??? ounces from that, but I am gonna guess I have done something wrong, there gonna die a horrible death and its all been for nothing... but hell throw it at me

ok so I read that by LST training I would lower the height to which the grew too. with it being NL the avg height should be 1.5m, so I figured LST through veg would reduce that to avg 1m, but into 1 week of flowering the plants have shot up 1m already should I expect even more of a shoot from them?

Looking good so far,What kind of nl do you have? Is it low odor? I want to try some nl myself. Grew one thc bomb and that shit stank .I can smell it on the other side of house when my wife opens the jar. Never growing that shit again.
