2nd grow Mistakes have been made

[allenfiel]

Hi Everyone,
getting towards the end of my second grow which I saw as a learning curve, trying out LST for the first time and using some bought seeds and freebies which came with them various varieties. Thought I would share with you. please feel free t point out my mistakes, I am looking for constructive critisism and tips to improve.

Grow space - DS90 90x90x170
Lights - LED Migro 300
Vent - 4" inline fan
Medium - plant magic soil supreme in 6.5l pot
Nutes - little bio silicon?? the OT Bloom in flowering 1 to 2 ml per litre
Seeds - All Autos
Started with:
1x Girl Scout Cookies (didn't pop)
1x White Moscow
1x Auto AK47 (discontinued old seed)
1x Sweet Gelato
2x Green Crack

About 2 weeks later I added:
1x Malana Bomb
1x Girl Scout Cookies
1x Blueberry Mango

Soaked seeds in water in dark for 48 hours then straight into finishing pots.

Used Plant Silicne?? (sorry I cant remember the name) sparingly during veg.
Fed OT bloom at 3 weeks 1ml/ltr and nute burned most of the earlier starters (something I seem to have a habit of - see pics)
Started the OT Bloom a week later with other 3 which worked ok.

Have LST most of them to some extent, only Malana Bomb and GSC havent been touched. I wanted to compare untrained and trained, also these 2 were very stocky and squat in veg and I was scared of snapping them (again!). These two looked strange in veg, more like rubber plants than weed and I thought they were some genetic mutants, but they look really good now.
I read an LST tutorial and when plants were big enough to bend to the edge of the pot I used pipe cleaners and paperclips to anchor them bend the stems, I managed to snap the stem of one Green Crack. It was ok when I left it but snapped next morning when I checked them, it has recovered reasonably well all things considered.

Overall I am fairly happy with these and the second batch of three have definitely benefitted from the mistakes I inflicted on the first but I think I still have some way to go getting to grips with nutes and watering. Still get a lot of nute burn on some (didn't know nute tolerance varied so much plant to plant - if thats even a thing ) and I was definitely letting them get too dry for a few weeks but think Im improving there.

Hoping to get some decent smoke out of these, comments good and bad most welcome these pics are from about 5 days ago.
I will post second batch in a post below as only 5 pics allowed.

Can anyone give me some advice on harvesting, I know roughly when to harvest, but how critical is it to get is spot on, will a few days early/late make much difference.
I am looking for a good head high with not too much couch lock.
I have a pocket microscope to inspect trichs but have read lot of conflicting advice abut clear/coudy/ambe amd Im not sure on pistils either.
I appreciate the harvest times are just a guide but how far out can they be?
My Sweet Gelato should be ready this week but looks a bit soon from my novice eye, what do you think if you can tell me anything from my not great pics.


My AK47 is not supposed to be ready for 2 weeks but looks almost ready to me.


Any advice would be appreciated, thanks.

Alright man, you got something to check the trichs with, microscope, loupe? I can get a ok zoomed in shot on a samsung s10+. There's a chart somewhere if you google it showing you when to harvest, depending on what kind of smoke you want, generally you'll want some amber trichs at least.

[allenfiel]

Thanks for the reply, much appreciated.
I have a 420 Microscope to look at tricomes but not sure what Im doing.
I will have a look for the chart you metioned.
Cheers,
Steve

Thanks for the heads up, having had another look, the Sweet Gelato is almost ready (mostly cloudy and a little amber on main cola), i would say 2 or 3 days and the AK47 still has a little time to go(loads of crystals but only about 30% cloudy trichs on colas).
Next question, should I feed only water for last week or does it not matter? I gave the Sweet Gel and AK just water last time a couple of days ago, should I continue with that or does it not matter with organic nutes?

[MrC]

Some ppl say 1 week some say 2, some say it doesn't matter in soil with organic and don't bother with a flush period. I intend to do a week flush from now on and then let it go bone dry before I chop. I use soil and organic nutes.

Organic soil doesn't need a flush but i would recommend a longer drying phase to pull more of the chlorophyll out of the plant. I don't grow organic, but do have a fella who's exclusive (teas and everything) and his stuff is always on point, solid nugs, sweet smoke and potent stench.

Thats interesting Karsa,
Never heard to not wash soil.

So u sayin hydrophonics and coco needs to be washed? Was this tested? As i am getting a hunch feeling coco does not need to be washed and a perfect dry will do better than a week of no nutes.
