Evening all. Day 34 since seeds went into coco, and really happy so far wth the results. Germinated seven seeds altogether, some were shit and not worthy, these four were my Highlanders (there can be only four). Have benefited from the assistance of so many of the crew here, managed to avoid seriously fucking up thanks to some timely advice.
First lesson learned was add perlite next time, I know rookie mistake, I got given some bad advice. It's not the end of the world I just wait longer between waterings. Next time I will add so I can do heaps regular fertigation.
I'm in a 4x4 wth 2x
Mars Hydro TSL 2000s side by side for 585 true watts at the wall. Have just moved them up as optimum spread is at 14" from canopy and they were growing into that. Moved up to about 17" to let the grow into it again - still only set at 30%. Should have more than enough ppfd to get me right the way through, we'll see how it works out for spectrum as we go but I'm pretty impressed with the node spacing of my four Green Crack, being about 70% sativa I was concerned about height but they are staying shrubby. All we're topped around day 30-32, have now begun to train fans and shoots aside to get maximum bid sites developing and fill out the canopy ready for trellis.
Had a lot of trouble working out watering schedule, lots of help from Aqua Man there, watering too often in 100% Coco definitely caused some minor root damage to one of the plants. See plant two below. Also tested my tap water the other day and realised EC is 0.7!!!! I have been giving Canna A+B at 1.7 and wondering why they are lacking magnesium and nitrogen. The big girl is obviously taking longer than the others to respond I guess due to size. I can only go up to 2.0 without worrying about nute burn which only gives me 1.3 EC to squeeze all my nutes into. Needless to say I've ordered an RO tap filter, will be here tomorrow. No more loading my Coco up with useless inaccessible salts from the water lines. In the meantime I went to the hardware and bought four gallons of distilled water to get me through. Can give the girls a proper 2.0 that is all good quality nutes. You can really see the remnants of that early lack of magnesium on those early leaves. I'm loving the colour and vibrancy of all the new growth after topping.
Girl 1 was the first to pop and has raced along. Signs of those small early deficiencies in older growth buy just explosive since topping about 5-6 days ago. My first attempts at LST trying to get the shoots out from under the fans.

Girl 2 suffered when I moved to more regular waterings which just didn't work. Another plant showed early signs but this one just didn't handle it. I've already cut the fan leaves of the first three nodes, I have wanted to cut any more off while it is recovering from topping but those two leaves just insist on flopping in the dirt. I know it's better to cut off damaged leaves but the plant will be okay with just its new growth?

Girl 3 was a strange one, popped upside down and needed help, recovered and has just plodded along, but loved being topped and has just exploded. As with girl 2 at the moment I'm doing a lot of fan tucking mostly, will start to tie down as they stretch for the light.

Girl 4 came off the bench after a couple didn't make it. Is a week younger than girl 1 in terms of germination date, but has done well, while perhaps taking a little longer to recover from topping. She's very airy and open so I hope that makes her easy to train and that her flowers aren't also airy..

Cheers for checking out my first grow. Hopefully some okay pics there. Really happy and grateful for loads of help and reassurance here so far. Peace and blaze.
