Septoria, deficiency, neither, I don’t know?

Beautiful! I have a 600 watt HPS. Do you know if those penetrate as well as LED’s?

If you didn’t guess. I had Ph problems. Too low. Stunted my bud growth and caused them to not stack very much. It also had a lot to do with the strains. Two other fellows that grew the same strain couldn’t get the buds to stack and swirl regardless. They wanted to be fat and chunky not huge and stacked. Lots of heavy Sativa Strains like BoomBoom has a tendency to make close node spacing and wild stacking. This is dried Boom Boom. Not all buds want to stack and won’t if the node spacing is way to wide. From stretching issues..list can go on as to why they don’t max out like the boutique buds some people grow. It’s gotta be done allll right for that sexy appeal. I choose yield and quality. It gets better every run as I check my boxes of Never let it happen again.

 

[Rama777]

I’m going for the balance of yield and quality myself. One thing I will say is that you have a lot more space for those four plants for the branches to spread horizontally.

That’s part of the reason that I feel like I should defoliate pretty heavily, if not just for airflow alone.

Yours look pretty cleaned up.

My plan is this right now, prune every 3 days and then the final pruning will be on day 21 (besides potential lite maintanence) but that will be mainly just the thorough lollipopping.

So I’ve got 3 defoliation sessions and one lollipop. I’m just gonna start taking off what feels right at the next pruning, post some pictures, and massively appreciate any feedback I get from anyone here :)) Thank you so much for your support and for not just telling me what I “should” do :))

 

[Bdubs]

Nice. That’s how we do. Collectively add input into the brain and make the move. I can tell you question everything. You’ll be a pro in no time.

 

[Rama777]

Thanks man. I can’t wait to be part of the team that’s bringing more to the table than just questions ;)

Got some leaves that are yellowing at the very bottom. Not the big fan leaves, just some of the little guys at the base of some branches.

Totally normal appearance for that at this stage yeah?

 

[Bdubs]

Mmm they are looking for more nitrogen to make rapid growth. Taking it from the lower leafs. Did you cut nitrogen a lot or just by a little? If you are in week 4 I never fret about a few leafs every 3-4 days, even to the point of dying off. Especially if I am close to a nutrient phase change. But the yellowing is a sign of nitrogen. Early one too. You still need nitrogen in flowering. It is what promotes the growth. But if you use too much it can cause excessive sugar leaf production and then it is hard to trim in harvest. So lots of people trim the line on nitrogen availability in flower.

 

[Bdubs]

I would t worry unless you get a couple more leafs fading in the next couple days. Individual leafs showing signs is never an immediate action, analyze frequency and then decide if I need to make a change. If that make sense.

 

[Rama777]

I have been tapering it down. I actually just watered for the first time with none of the veg nutes blended in. The NPK of my bloom nutes are 5-5-12 so there still going to be getting that much for a few more weeks. I’m at day 8 of 12/12. One issue I’ve had is that two of the plants are sensitive to nitrogen and two are not. But, I haven’t had time to mix feedings for the individual needs so I’ve struck a balance. Two are maybe not getting as much as they could use, and two are getting slightly more.

I’ll keep my eyes peeled for any trend that may be forming. My eyes are always peeled honestly..

 

[Rama777]

Oh and my VPD is pretty damn high so I kind of have a feeling that the plants are rapidly taking up too much nitrogen and not leaving enough behind for later. Could be an issue down the road.

 

[Rama777]

There are about 4 of these leaves that have lite fading at the base of the largest plant. I’m all ears if you have any recommendations.

 

[Rama777]

Or you know what, all plants but maybe one have a few hints of lite fading on some of the base smaller leaves. I’ll monitor them until the next watering and blend back in some Veg nutes if it progresses until what, the end of week 2? Solid plan?

 

[Bdubs]

Feeding water only is going to dilute the soil a bit of nutrients. Are you measuring and recording PPM of runoff?

 

[Bdubs]

Your grow looks good for sure. What was the last thing you did differently before the yellowing? Was it the skipping over a Feed and watering?

 

[Rama777]

I didn’t skip a feed. I just cut out the veg nutes and used 100% bloom nutes. I had been mixing the two up until yesterday.

I’ve never watered until runoff. All the plants showed some excess nitrogen a few weeks ago. I had cut back on the ppm. The company recommended 825ppm twice a week which allowed for water only sometimes but I stopped doing that a while ago and instead just gave them 550-600ppm every watering, although 275 of that was always calmag so they didn’t get a whole lot. But, other people who have grown this strain said they weren’t heavy feeders and I’ve seen sporadic downward facing tips all along which led me to believe that they were getting what they needed.

 

[Bdubs]

Accumulative, I use 9N at 1050ppm right now but my dose of N is half that from late veg nutrients, working through week 5. Late veg 1250ppm start. Upon flipping, half my nitrogen. So basically your 5N bloom nutes is legit it sounds. Comparative to what I am doing. Although I don’t have a magic NPK one bottle bloom nutrient. Biomen N is a 5-0-0 you could add a little and boost her up maybe?

 

[Rama777]

I do like Biomin on my produce farm. Haven’t tried the N formula. I suppose I could throw down a dusting of alfalfa meal on the soil surface too.

1250ppm, that’s hard for me to imagine. Pretty sure that would cook these ladies.

But again I also think that my often having a high VPD while the lights are on limits their capacity for higher strength feedings.

 

[Rama777]

Looking forward to switching to LEDs in the spring. It will be far easier in my context to keep the VPD dialed in.

 

[Rama777]

Actually I’m gonna just see if I can work with what I’ve been using. I am going to see how they respond to higher strength nutrients with the switch to bloom nutes. If it’s too much, are the initial symptoms about the same as with excess nitrogen? Tip burn and downward claw?

 

[Rama777]

Seems to have spread to even more lower leaves over the last dark period.. Also it’s moving upwards though still very low.

 

[Bdubs]

More nutrients more light comes to mind though.
