4x4 - Northern Lights & Gorilla Glue - RDWC

Phonetic · Apr 6, 2020

Welcome to my grow journal! Comments are welcome, or you can just light one up and follow along :joint:

This is my first grow, so I'm sure I'll have made some mistakes and will make more and that is why I welcome any and all comments, questions, or advice! Just be nice :hump:

Setup-
1xHLG 550 v2 rspec
1x4x4 grow tent
1x4 plant rdwc system (13 gallon buckets)
1xWater chiller

Nutrients-
Flora Grow, Bloom, Micro

Plants-
3xNorthern Lights
3xGorilla Glue

Seeds placed in rapid rooters on January 10, 2020.

Here they are 4 days later-

At this point I was still setting up the grow space. About two weeks later, I placed the rapid rooters directly into the hydroton I used to fill the 4 net pots.

I think I was over saturating the rapid rooters, which seemed to slow the growth quite a bit, as they were still very small after 2 weeks.

Yes, I did plant 6 seeds with only 4 net pots :bigjoint:

I regret doing that there was no need, as I vegged for about 60 more days after the above picture, and they all got huge. The two net pots with 1 plant were both topped for 8 mains. I made my attempt at mainlining and its worked well! The other 2 net pots with 2 plants each, were topped for 4 mains, so each net pot has a total of 8 mains.

This is the progress on March 4th (54 days after placing the seeds into the rapid rooters).

Gorilla glue is on the left side of the tent, northern lights on the right side of the tent.

If you notice the rapid rooters has 3 labeled GSC. I tried 10 seeds of Girl Scout cookies and not even 1 of them popped! So I took an L on those seeds and continued with the 6 that popped.

March 12 (62 days from seed)-

Got some high CFM support poles to help the tent walls from being sucked in.

This is a few days earlier, when I was training one of the plants too hard, its stem split down the middle, right at the base of the plant.

Taped it back up-

Now the fun is really starting, they are getting big! The one on the back right, is the plant that had its main stem split down the middle. It outgrew the other plants almost by 2x!!

March 29 (79 days from seed)-

A look at the setup outside of the tent-

Water chiller is keeping the water temperature between 66 and 68 degrees.

Phonetic · Apr 6, 2020

Switched to flowering on March 27th. Here they are today, April 6th (87 days from seed, 10 days into flower)-

This is after 2 heavy defoliations and many minor defoliations removing bigger fan leaves that are blocking light from reaching the lower portions of the plants. It's amazing how fast these have recovered. I think the RDWC system is part of the cause of the rapid recovery and extreme growth I'm seeing.

The largest plant is the one that had its stem split right at the base of the plant. I've also had to super crop it slightly to try to keep its height at a reasonable level.

Here's the base of that plant now, its recovered so well-

The other plant next to this one has turned into a runt. The big plant seemed to steal most of the light as it grew and blocked the other plant. I've cut most of that plant off since the leaves were all small and shielded from light.

And here is a big knuckle that formed after super cropping-

Show me those roots! One of the netpots has begun to split because the roots are getting bigger-

Phonetic · Apr 6, 2020

Current ppm is 820-830. Seeing some leaves starting to show signs of burn and/or deficiency of some sort on other leaves so I will change the reservoir since it's been about 2 weeks and now I'm thinking the nutes may be out of balance.

I'm using RO water and adding 1 tsp of cal mag / gallon of RO water. I'll drop that down to half a tsp / gallon next reservoir change.

April 7th (88 days from seed, 11 days into flower)-

They grew a fair amount taller in just a single day...the stretch is real!

Close up-

Phonetic · Apr 8, 2020

Just did a res change. The PPM of the source water is close to 0, but after refilling, the PPM (before adding any nutes) was 100.

There was maybe a little less than half a gallon of water left (in total) in the bottoms of the 5 buckets before I refilled it. I'm wondering if that's why the PPM went up after refilling but before adding the nutes. Or the roots are holding some nutes?

I'm not really sure why, and I'm shooting for perfection in my grow so any tips on why this may have happened would be much appreciated!!

Should I do a better job draining or not worry about it?

April 14th (95 days from seed, 18 days into flower)-

The plant that's stem split right down the middle very early on, has decided it's actually a tree and belongs closer to the sky. This thing is crazy how much bigger it is than the other plants!!

I feel like if that plant was centered in the tent, it would be able to fill the entire 4x4 by itself!

Happy 420

April 20th (101 days from seed, 24 days into flower)-

This is after defoliating a lot! But I still plan to take quite a bit more off over the next few days before I stop defoliating for good. Also noticed some yellowing which appears to be light burn on the tallest parts of the big plant. So I rearranged the carbon filter in the tent and got the light moved up another 8 inches. That's as high as it can go.

There is for sure some nute burn. My pH has been dropping a lot and the ppm only dropping a little. After adding water and phUp consistently for a few days this oddity continues to happen, even after a fresh reservoir change.

Plants look OK to me other than the slight nute burn, so I'll let it play out and continue maintaining the pH with phUp and fresh RO water, with another res change in a few days. Hopefully the ph will stabilize soon. Been happening for about a week now.

Great looking grow. Have you finished it?
