Between work knocking me down and stealing most of my time...
Sarsaparilla

Receiving only 1-2 fertigations a day she's not only survived she's growing well. 41" tall and starting to fill out in a 1/2 gallon nursery pot.

Slugs more than likely. She (yup, I see hairs) still has that bitten leaf

Very common around here

It's unfortunate I wasn't able to update often due to work bla bla bla but this is her (I see hairs damn it)

She's all of 44" in a half gallon nursery pot. When was the last time you grew a 4' plant in a half gallon pot? Yeah, this coconut coir and hydro nutes rock.

This girl got no more than two fertigations a day for several weeks due to bla bla bla and still turned out okay. Granted not GREAT like the 5 footer in half gal (there are picks somewhere honest of that beast same strain as this one, Sarsaparilla - GMO Rootbeer x Pure Michigan and tested at 30+/-% THC. Made a bunch of seeds last year.

She was flipped a couple weeks ago, I don't remember what day

I made several hundred coconut oil caps hundreds of gummies and Rand a bunch through the hash bags. This stuff rocks my world

Anyway, fertigate 3-4 x's a day, every day and the growth will make this one look like a seedling not really but it will be much bigger and stronger

Almost 4 weeks since flip

Many days in the past 4 weeks she's only had 1 fetigation a day which is not ideal. 3-5 x's is best and she'd be a lot taller than 4' and a lot bushier but she's turning out well. 4-5 more weeks and she'll be ready for harvest.

This is really the easiest way to grow. She's been on the East side of the house since flip so only getting maybe 4-5 hrs of direct sun from morning to noonish and is in shade the rest of the day so the coconut coir doesn't dry out as quickly as plants receiving direct light all day.

Hey i see you use masterblend as me.i wanted to ask you do you change calcium nitrate for calcium sulfate on the last few weeks or do you keep it the same whole grow?

Hell yeah man, nice job.....coco and rockwool are THE true efficiency of grow !!

The smaller the pot the better, i used to grow monsters in the rockwool starter cubes....insane!

Is it true that soil grows are cheaper to setup if you are starting from new, but after few runs everyone should look into more efficient ways to grow....like Coco or Rockwool on a automated watering either DTW or F&D....

I've tried a lot of different combinations but I've found little difference so now I just leave the mix at full strength until harvest. I like EASY

did you notice any differences with less nitrogen

None. For a year I was cutting the calicum in half and upping the MB 1 1/2 x's after flip and didn't seem to make a difference BUT by all means try it and any other ideas that come to mind.

I even tried cutting out the Ca as the MB does have some as well as my water but the fade (yellowing leaves) became more prominent toward the end.

This year I've started at about 20% of full strength at 7+ days old. Within 3 weeks I up it to 50% and keep that through veg and then up it to 100% for flower. Other than aphids, spider mites and PM the plants are growing very well
