2022年 10月 15日 at pm7:16 #5634
I have been running into a few issues on back to back runs. I usually run 4 plants, but have been scroging a single plant & seeing issues starting at flower set, and progressing thereafter.
Running 660w led on 60% currently because of the yellowing.
Hanging height: 20”
4×4 tent. 6” exhaust running 24/7
Environment: 66-70f/50% RH – lights out
76-80F/40-45% rh – lights on.
2x 4” fans moving air above canopy & 1x 6” oscillating fan below.
strain: banana Kush
Feed formula: synthetic
Athena Ballance -7ml
1tsp epsom salt
GH maxibloom 1tsp per gal.
Ppm is 1145-1180, but only about 750-800 of that is from the maxi.
Tap is 140 ppm
The rest is the Epsom.
I’m a little toasted & neglected to try out the template @somatek & I were compiling.
Hope everyone is enjoying the weekend.

Yes most definitely. Something has to feed that Bertha of a plant. I’m a fan of more often than increasing the dose. Once you put to much into the bud you can’t get it back out. I personally think there better under fed than over. The way you feed might not allow for that, but you gotta be watering that beast often.
There looking pretty good and nothing I don’t think you won’t be able to correct.

Thanks got getting back to me on this. It’s been beating my brain, and I’m always leaning towards either I’m misfiring with my watering habits, or she wants a lot more. I give her more & her tips burn. I am only interested in the finished flower, but I do not want to kill off all the leaves. I’ve been able to bring back the green in the leaves before, but it was on a small clone. Didn’t take much to fix. I fed the same as my teens & they bounced back fine.
side note: I need to start transplanting sooner than later as well. Bad habit there.

In my experience, yes.
I also had to learn to be careful with the water and not to overwater it. This often had the same effect on me.

This is a tough game to master. Ive tried both ends of the spectrum for everything. I always get the same yellowing burning tips and purple stalks. Even with watering habits, I buttchugged 8 5 gallon fabric pots submerged until maximum saturation in a storage tote taking around 15 gallons lol. On the other end I watered 8 girls water can style with just 5 gallons. Only similarity is I water when the weight of the pot and plant are light.

I really appreciate your responses @Terploverr & @Loves2Trim
I think the yellowing may be a little beyond repair for the most part. I am waiting for the leaves to eventually crisp up & fall off. If they take their time doing so.. I’ll be almost sure I should have been feeding this heffer more from the get go. lol
On the other hand if I’m wrong.. my floor will be full of dead leaves by tomorrow. 😅😅
I just need to push her for another 4-6 weeks & get something else in there.

I just stopped in to pick up some knowledge. But I wanted to say that your plant is amazing. That is what I wanted to do but I’m still trying to build up a collection of herb. Plus i didn’t trust myself enough to not fuck it up. Yours truly looks amazing.
2022年 10月 16日 at pm7:25 #6047
Thank you. I feel like I could have paid more attention. I have way too much on my plate currently, and she’s taken a hit. We’re going to rock this thing til the wheels fall off either way. With less foliage.. if it in fact comes to be, will put more pressure on me & my feeding/waterings habits.
Hold my beer guys 😆😆😆🍺

You are the man @cannabliss that banana 🍌 Kush is going to be out of this world 🌎 by the looks of her so far.I think she’s beautiful in this stage of the game you are with her.My ladies always and I mean always eat more when they are budding past week 5 or no later than 6 weeks under.Im not sure if that knowledge will help you,but I personally have a bad habit to water on the heavier side.Thats a problem I’m working on though.With that said the pots are always lighter than normal when they are flowering at that period I spoke of .
2022年 10月 17日 at pm11:52 #6234
I think I kept her in a small pot too long. The roots didn’t populate the entire pot is what I’m guessing, so I think I have a section in my pot that stays over saturated due to no roots being there to drink. It throws me off on lifting the pot to check.
I have a really bad habit of leaving plants in small containers too long.. 1gal max
I should have scarred the roots before transplanting. Meaning slice them on the bottom of the root ball.

Yeah nice grow man! What light is that?

Hey bro, have you seen the phlizon FD 6500 and if so do you think it’s a solid light. It’s supposed to be Samsung diodes and all that the inventronics driver the same driver that the hlg scorpion and blackbird has so I’m having a hard time believing them that’s why I ask do you think it’s a solid 650 watt light it’s 399.00 I’m between that and I may have the cash for the se 5000 if I unfortunately don’t win it,but I’m going to try to win it would be the best blessing of the year for me.
Thanks as always for your help bro @cannabliss

I replied to your PM on that.

So the first thing that stands out looking at the info is your VPD is up around 1.64-2+ kPa which will be causing the stomata to close and limit transpiration/nutrient availability. If you watering or feeding schedules are off, especially if they’re on the light feeding/under watering side those will also both exasperate the issue.
So to answer your question, bigger plants don’t specifically need stronger feedings but looking at your conditions my guess is that increasing them will have a positive effect on plant health/yield. Although with the tap water having 140 PPM (what conversion does your meter use by the by? that’s useful to include if you’re using PPM over EC, although I generally just use EC online to avoid confusion) you have to be careful about nutrient lock out, so if you’re increasing the feeding amount, when you give them straight water every 3 or 4th feeding I’d give them extra and have a very dilute feeding as that’s more effective at flushing excess nutes then straight water due the chemistry.

Once The light comes back on today I will let it warm up in there a bit, maybe for an hour.. then I will take the monitored readings & leaf surface temp to see where I am, and try to dial it in.

It’s all the little things we forget about when we see problems that often are the core issue, hope you figure out what’s going on

I’ve become a bit slack on vpd lately, you just reminded me how important it is.
2022年 10月 19日 at am5:12 #6412
Everything in a grow is interdependent on the other factors. Nutrient dose has less to do with plant size then with VPD which determines the evapotranspiration rate and growth stage.

So glad to be picking up theese great tips you guys are the best, straight up!
