12/26 1130 - Began germination of two NL auto seeds from Nirvana.
12/28 1730 - 1 NL seed went into a 2 gallon bag.
12/30 1800 - 1 NL seed sent into a 1 gallon bag.
1/4 0800 - Girls looking ok. Accidentally squirted too much water (syringe) at NL #2 but don't think I broke the stem. Oopsies.
1/22 - NL1 is on week 4 and NL2 is on week 3. NL2 needs stability, found it blown over mostly and the plant seems sort of smushed right now. Trying to brace it and allow it to grow out. I have soft wire ties en route on delivery. These thin ones don't work well for me.
1/24 - Using nutrients. Watered to runoff for each plant since they are smaller in volume (1 & 2 gallons).
1/28 - Final days of week 4. Added some pictures.
1/30 - Start of week 5, just about. Did some LST to both Northern Lights plants today to even out the canopy. Will see how they react over the next few days.
2/5 - Following cocoforcannabis watering schedule. Am now using the 'From Flip to Pistils' column. Not using any supplemental nutrients beyond what I've listed. This is the beginning of week 6 since they sprouted on 1/1-1/4, rounding here for the sake of a diary entry.
2/13 - A lot happened this past week.
-The two NL plants went into a new 4x4 under a new light, the MIGRO ARAY 3. I am not sure if I am keeping that light or going with the plan of replacing the mars hydro tsw2000 in my 3x3. I am still shopping for a new 4x4 light.
-I am not running a heater in the new tent so daytime temp average has been ~73F and night time ~65F. Definitely a colder environment from the old setup in one 3x3 with an oil heater running 24/7 on low.
-I did also add a seedling mat, set to high, beneath all of the plants. Not sure if it is really helping but I like to think it helps warm them in a more economical way than the dedicated oil heater.
-Added a few additional supplements (Armor Si, Diamond Nectar, Rapid Start). Ended up going to a hydroponics store over the weekend and saw some good prices (/bottle).
The gray pot is the 1 gal and the black, 2 gal.
One thing I have learned so far is that I hate watering smaller than 3 gallon pots. It's too frequent.
I have been observing slight twisting in new growth. Water going into the plants pH has recently been upped to ~6.0 - 6.2 due to Armor Si being added and needing pH down to combat it. Light is 12" from the plants at 100% (275w light).
I think your light is too close, but you should use a light meter to figure that out. or look at your lights manufacture specs and see the recommended hang heights and dim settings.

They recommend 100% at 12" but it might be to much. try backing it off to 15" or dimming it 10% if it allows that. My lights only dim in 20% increments.
2/20 - A strong vegetation smell permeates the floor above the tent location. I am not running a carbon filter on the inline. Both plants seem to be healthy. You will see some twisting and light canoeing, the new light (MIGRO ARAY 3) has been pretty strong at 80% dimmer. The plants have also been stretching and I failed to bring the light up to accommodate it. Have recently been watering 2x every 24h but I am going to try and cut back to 1x a day, see how it goes.
Tops are now receiving ~40 DLI.
3/6 - Another week of flower behind the girls. Buds are beginning to stack. Progressing smoothly without many hiccups. Maybe some early deficiency signs on lower leaves but nothing that looks significant or that obviously needs attention.
3/13 - Believe both plants are showing Magnesium deficiency signs. Many yellowing leaves. Will be doubling the calmag amount from 2.5ml to 5 for a week or two and see how they respond. Any tips, please shoot em my way! Again, #1 is a 2gal, and #2 is a 1 gal (stretch).
Decided to measure my runoff PPM out of the blue.. my input is ~600 PPM and my runoff is ~1400 PPM. I haven't exactly achieved 20% in my runoffs when watering. For my next watering, should I increase the volume until I register a lowered runoff? This is week 13.
Hey there!
Checking your runoff PPM is a smart move to monitor what's going on with your plant's nutrient uptake. It's normal for the runoff PPM to be higher than the input, but a significant increase like that could indicate a buildup of salts in your growing medium.
Since your input is around 600 PPM and your runoff is at 1400 PPM, it suggests that your plant might not be fully utilizing all the nutrients you're giving it, leading to accumulation in the medium.
Increasing the volume of water you're giving until you see a decrease in runoff PPM can help flush out some of those excess salts. Aim to achieve at least 20% runoff to ensure thorough flushing.
However, considering you're in week 13 of your auto Northern Lights, you need to be cautious about overwatering or causing stress to your plant. Gradually increase the volume of water over a couple of watering sessions to avoid shocking your plant.
Additionally, if you haven't already, it might be a good idea to check the pH of your runoff as well. Fluctuations in pH can affect nutrient uptake, so ensuring it's within the proper range can help your plant better absorb nutrients.
Overall, a little adjustment in your watering routine should help rebalance things and ensure your plant gets what it needs without any excess buildup. Happy growing!
Began measuring the runoff EC over the past week and noticed it a full point higher than where I wanted to be. Have been running additional volume of nutrient water through the plants to push more of the salts out. Plant 1 (purple) has been tacoing lately. Light (700w) is at 50% and Photone is reading ~500ppfd. It is the only plant showing what I would say is 'severe' taco-ing. Tried lowering the intensity of the light infinitesimally but going to ride it out and see how it goes. Have not really examined trichomes at this point, way too many white pistils still.
Two NL plants (#1 and #2).
At some point in the past week or two, I began noticing the foxtailing going on in all 3 plants in the 4x4. It had completely escaped my daily checking and I attribute it to the new light I had in the 4x4. It's oversized but when measuring the wattage, it was only consuming ~300W.
Though it was running at 50%, I had a white vivosun fan next to a port in the ACI tent which (I think) heated up the rubber seal and rubbed off. I attached a picture of it last. Reported it to ACI customer service but haven't heard back yet. Just want to bring it to their attention.
Overall temp/rH in tent has been 72F 50% with lights on. The light must have been far too close (10in) to the top cola. So, I turned the light down 5% and raised it at least 6in. Another large sign was the tacoing but not all 3 plants were displaying it so intensely, thus I had ignored it too.
Flushing this week. Runoff EC is already at 500 on sampling but I will push it out a few days while I continue to look at trichomes.
Please let me know your thoughts on the foxtailing! I feel like I semi-ruined the outcome but live and learn!
Harvested 4/8 - hanging at 65F - 63%. Trying to get humidity down just a little bit more by defoliating some dying leaves. May run a large dehumidifier in the lung room as the basement is showing 65% rH or so.
@SirBudAlotts, So far so good. Sprouted quickly and looked healthy as seedlings. Though, out of the two, one had stem-support issues early on and had caught it blown over one morning early on. That was my fault, should have had some support for the main stem. Hoping they respond well to the light LST I did today. One is a 2 gal, the other a 1gal.
