December 27th:
This week I decided up the nutrients quite a bit, about 200ppm higher than before (1.75ml/l instead of 1.25).
I gave each plant at least 3L of water. Some of the thirstier ones got 3.5L. The watering details are as follows:
Started with 24L
Start ppm = 50
Calmag addition - 1ml/l x 24
Post calmag ppm = 225
GMB addition = 1.75ml/l x 24
post GMB ppm = 749ppm
post GMB pH = 5.81 on meter (might be off by -0.18) so it could be ~6
Runoff details (pH/ppm):
2 - 6.36/1360
3 - 6.43/1200
4 - 6.30/921
5 - 6.36/979
6 - 6.31/1130
8 - 6.34/1050
9 - 6.45/915
I've also switched out the 400w bulb to a 600w.
Every week there are some leaves on the bottom that turn yellow and soggy and eventually crisp up and die. Not sure what it is as I feel like I'm definitely giving it enough N with the addition of the nutes as well as the calmag+ which is 2-0-0. Growth on plants looks otherwise healthy with the buds starting to develop now.
One of the plants has been getting this white dots on them. It looks almost like it's dried up salt. I'm not sure if it's from foliar spray or what. It doesn't really look like white powdery mildew pictures that I've seen online. The dots are only forming on the edges of the leaves. None of the other plants have this.

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
SourDeezstarted grow question 5 years ago
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.
