First Time Grower: Northern Lights Autoflower, 600W LED

That algae came quick! hey, I see that hydrometer sensor dangling to the left of the humidifier. I have an app for mine, I'm guessing you do to? Anyway, I have it set to send me an alert to my phone if the temp/ humidity goes out of my set range, as long as I'm in the house so I can intervene. It sucks when you wake up and find out something broke. Keep those videos up! :blunt:
Edit: I totally don't know if its called a hydrometer
 
Day 13
------
Temp : 24-28C
RH : 70
Light : 75% @ 60cm for 18h
Water : no water given
Video update :

Some of the plants are showing curling/twisting leaves. I have no idea whats causing this, since I ph in on the right spot.
Might be a calmag deficiency, I will find out by tomorrow!

Its called a Hygrometer. And yes the white one is a standard one where I can digitaly see it, but I also have a small blue one which is linked to my phone, but its using BLUETOOTH, so I only get alerted if im closeby, however I think im going to buy the WiFi gateway so I get notified on the spot!
 
Day 14
------
Temp : 24-28C
RH : 60
Light : 50% @ 60cm for 18h
Water : 3L for flush + 2 x 400ML in the morning & Evening + Foliar spray in morning and evening
Video update :

Big update today! After a night researching, and talking to Dr.MJ Coco from cocoforcannabis.com, he told me that I was facing a starting cal-mag problem. So he suggested me to fully flush my medium with the nutes solution diluted to 0.6EC untill my runoff was close to 0.6EC. I had to pour down 3L for each container, in order to get around 0.6EC in the runoff. I did this in the night of the 13th day. In the morning I also did a foliar spray just before lights on (RO water with 2ML/L of Sensi Cal Mag) which I sprayed on the leaves and under the leaves 15 min before lights on. I then continued to give another watering using the same nutrient solution this time at 0.7EC and I needed around 400ml per pot to get a decent run-off. I also changed the floor of my tent, so its easier to manage run-off. Last I gave them another watering 8h later, again same nutrient solution at 0.7EC and 400ml per bucket. Just after lights of tonight, I will be doing another cal-mag spray. Hoping to see the girls looking better tomorrow! Fingers crossed :)

Video update :

Today we start week 3 of our grow. We are at day 15, and not really much to report. We will do our 2 feedings today at 400ml each pot, with the nutrient solution written down below. After we make the solution, we will dilute it using RO water to the ec we want it to be. Usually the mix I make comes down to 1.1EC so I use a few Liters of RO water to get it at 0.7ec.

Just after lights off, I will do another foliar spray of the calmag, to help the plant get on her way.

We are also still doing the Foliar spray at night hoping to fix the calmag issue.

Week 2 Summarize
============

In todays video I sum up everything that happened in week 2 of my grow series. All the problems I faced and everything that happened in general!

Day 17
------
Temp : 24-26C
RH : 60-70%
Light : 50% @ 60cm for 18h
Water : 400ml of nutrient mix twice a day
EC : 0.9
Video update :

Today we are trying to fix our Iron deficiency, the only way for me to solve this is add more Calmag & more base nute part A since those are the 2 that contain iron.
I adapted my solution a little bit down below. Other than that, the rhino skin is really thickening the stems, so I like that :)

Nutrient solution
Sensi Cal-Mag Extra : 1,5ml/L
Sensi Coco Grow A : 1,5ml/L

Video update :

Today we did our first LST (Low Stress Training) on the girls. I feel they are old enough to start getting this training as they all developed a 3rd node.
I also upped the nutrient solution to 0.9EC at morning and 1.0EC in the evening.

Day 19
------
Temp : 24-26C
RH : 60-70%
Light : 50% @ 60cm for 18h
Water : 400ml of nutrient mix twice a day
EC : 1.0
Video update :

Wow! They grew ALOT since yesterday, the nutes and LST are really doing their job, and I can see them grew in front of my eyes. Amazing!
We upped the feeding to 1.0EC while dropping the calmag a little, since we want her to get other nutes aswell at a higher rate, since calmag has the tendency to raise EC alot.

Nutrient solution
Sensi Cal-Mag Extra : 0.5ml/L
Sensi Coco Grow A : 1,5ml/L

Day 20
------
Temp : 24-26C
RH : 60-70%
Light : 50% @ 60cm for 18h
Water : 400ml of nutrient mix twice a day
EC : 1.1
Video update :

They are growing strong every day, every day I have to redo the tie-downs since they are growing out of them. Today I measured ph & ec of some of the pots run-off, and they seemed high (6.3 to 6.5) and all having an EC lower than 0.9 so they are feeding well, but the pH is problematic. But after talking to some expert growers, they suggested that Runoff PH is not a problem, since PH is managed by the roots themselfs. As long as EC is lower or equal, we are on the right track :)
I flushed 1 girl which is suffering from a Nitrogen Toxicity, only giving her plain ph'd water tonight, hoping to see something better tomorrow. Im also gonna leave out the Rhino Skin/Cal Mag/B52 in tonights feed.

Nutrient solution
Sensi Coco Grow A : 2ml/L
Sensi Coco Grow B : 2ml/L

Today I tied some of the plants down again since they pulled loose their straps. I gave them another feeding except for the N-Tox plant which I gave a feeding of 0.7EC.
I buffered every watering little lower to 5.7ph.

Man you jumped in with both feet! Nice setup. I know nothing about coco or the nutes you’re using, but I’ll follow along. I just finished my second grow if you want to check it out. Link in my sig.

Hey rick I love his setup and videos. He's using a lot of nutes from Advanced Nutrients. I use it too. Cup-winning company.
 
Day 22
------
Temp : 24-26C
RH : 65
Light : 50% @ 60cm for 18h
Water : 400ml of nutrient mix three
EC : 1.1
Video update :

Our girls are showing their first pistils! Good news! Some of the plants have started making pistils, currently 5 out of 18 plants are showing the pistils, and entering pre-flower. When most of the girls show signs of pistils we will start introducing the BLOOM nutrients.
After measuring our EC today, I noticed that run-off was between 0.5-0.7, which means the girls are feeding ALOT. So we are going to implement an extra feed so we get 3 feeds in total per day untill we have the dripsystem.
I also changed the position of the fans today to blow over the plants and not directly on them, since I think what was causing the sad leaves was a sign of wind burn.

Nutrient solution
Sensi Coco Grow A : 2ml/L
Sensi Coco Grow B : 2ml/L
