The seeds I used were Seedsman Northern Lights Auto. They all sprouted to 100% success.
During the germ phase I had kept them in a humidity dome at about ~70% humidity/ 27c. I used 2x 60w CFLs at 6500k about 5 inches above the dome. After potting, I placed them under a Solistek 10K MH by accident because I didn't know it was a "finishing"bulb. Anyway, I maintained a distance of about 30 inches from the top of the plants for the first week after potting. pH of water I was giving them for the first couple weeks was relatively unknown because broken pH meter, but i assume around 7.
November 7th - I germinated these seeds in rockwool cubes. I used soaked them in a bit of GMB from AN first at a dilution of about 1ml in 1L of water. I dropped the seeds with the pointed side up, and then I covered the hole with coco coir rather than covering the hole up with the rockwool. My reasoning for this was that I felt perhaps the rockwool would be difficult for the sprout to penetrate up.
November 10th - After the second day, I started seeing the sprout come up through the coir. Within 3 days half of them had sprouted (#1-6). This is when I potted numbers 1-6 which were about 3cm tall when I potted them and a couple of them had the root coming out of the bottom of the rockwool. Number 7 was potted the next day (November 11th).
Numbers 8-10 took a couple days to sprout and didn't look as healthy. I kept them in the humidity dome a couple days longer and planted them on November 13th. Number 7's cotyledon looked twisted and eventually within 2 weeks I got rid of it because it just kept coming out deformed. Number 10 would eventually try out and die within a few days of potting. And number 9 would grow much slower compared to the others.
Number 3 would grow well, but it started out with certain "bleached" patches all throughout the initial serrated leaves and new growth as well. These symptoms would appear on number 5 and 6 as well, but to a much lesser degree. Closer pictures of this will be in the next week's diary.
The substrate ratio is as follows:
Compost : Coco Coir : Perlite : Vermiculite
Plant 1 - 3:3:3
Plant 2 - 3:3:3
Plant 3 - 3:3:3
Plant 4 - 3:3:3
Plant 5 - 3:2:3
Plant 6 - 3:2:3
Plant 7 - 3:3:2:1
Plant 8 - 3:3:2:1
Plant 9 - 3:3:2:1
Plant 10 - 3:3:2:1
Plant #3 (pic above) started as a sprout with discoloration. Now on its 4th node, the plant is still affected. Some other plants seem to have it to a lesser degree. I learned it may be TMV, but they are healthy and growing well other than this slight discoloration. Any thoughts?
No tobacco mosaic virus,I don't even believe that virus to be spread over cannabis plants.You run pots of the same strain,it's most likely a mutation like @SpinnerCaribbean explained. Newer growths look good,no mosaic virus
Plant #1 started out last week with light colored patches on the leaves of the first 3 nodes. The lighter green patches turned into a rustier color. Rest of plant looks healthy. Also all other plants aren't affected and are growing lots of branches, but #1 is not. Any ideas?
For some reason the microbial life in your soil isn't buffering the pH correctly probably from overwatering ever so slightly up to two or three weeks ago . If you don't have access to pH things you probably don't have access to anything right ? If you did have access you would be looking for beneficial bacteria, enzymes or humic acid (buffers to 6.5). Since you don't what you want to do is let the pot dry a bit more than usual then water very carefully with molasses, hopefully the sugar will feed her beneficial bacteria, make sure you get rid of compacting of the soil just by squeezing your fabric pot. Hope this helps 👊🏻
@SourDeez, nah like i said input 6.0 but you want to measure 6.5 on the way out, this should be done by your soil naturally, but that's not happening. Adding silica in flower is going to cause more harm than good (pH issues with silica) . This problem seems like it's got worse and the pH has not fully stabilised. Instead of silica , try adding humic acid with your feeds. Humic acid will pH to 6.5 . The pH perfect nutrients are not exactly pH perfect sometimes - go figure ! 👊
@CRiSPrGrow, Thanks for the fast reply. What's weird is all of the plants are the same strain but each one seems to be showing different things. Like Number 6 on week 7 has just a single leaf that has a bunch of black and also one leaf with a huge yellow spot that I never noticed (Definitely wasn't like that last week). I still think I have pH problems or the soil is to Alkaline but it's really just a guess. I water in at about pH 6 and then the runoff comes out at 6.8ish. The silica blast is coming today, do you think I should pH my water up to like 6.5?🙏
@SourDeez, good news, best i can tell that's from the pH fluctuations from before and the problem seems to have "stopped" spreading, the affected leafs wont recover as in get better, and the damage done "gets worse" in the sense the necrosis completes, give it another week of monitoring if you can see the issue's not spreading or getting that much worse then you can pull it off lol . that's actually not that bad with the damage, think you managed to rectify the situation quick enough to avoid the worst 👊
The greyish spots look like residue from a splash during watering and the worsening splotchy burn patches could be from a pH fluctuation like last week or something , if it stopped spreading means the soil is buffering itself correctly again 👍🏻
@CRiSPrGrow, Hey dude thanks so much for taking the time to answer my questions on my first grow. I didn't even know this comments section existed as I'm new to the site. It's weird because I wasn't sure if the gray/brown spots were spreading or if they were already there and I just didn't notice. They're hard to notice in the gray stage, but once they're brown it's very apparent. Now I kinda regret that I flushed it today. Anyway, I do have one more question. In my week 5 post that I just uploaded I took a picture of some "soggy" lower leaves that sag and eventually dry up. Is this just natural defoliation or a sign of something else?
Thanks again!
Great looking grow! I am growing the same strain from seedsman, and the pics you listed in week 2 look just like what's on my plant. It's my first time growing this strain, maybe something in the genetics?
Either way, I'm around day 40 with it now, and it's looking healthy, but same weird coloration on the leaves this whole time.
