Fungus , bugs or deficiency

I’m using advanced nutrients 3 part. Local grow store said to use recommended dosing if using Ro water. Doing that my ppm was around the 1300/1400 mark.

I adjusted down and it’s now at around 750. In order I mix my Rez.
15ML per 5 gallon of sensi cal mag xtra
1 ML per gallon of hydroguard
I’m using 6ML per gallon X 5 so 30ml of An micro , grow , bloom.
15ML of big bud per 5 Gallons
15ML carboload per 5 Gallons

Tent temps 71/82
Rez temps 69/73
Rh 50%.
lights- 2 hydrocrunch 240 watts , 20 inches above plants

Need help to identify the issue. First grow and don’t have any local friends who grow to run this question by.
I am in end of week 4 flower.

Thrips, spider mites, leaf seportia?
Or just a serious cal , potassium issue?

It does look like it could be a calcium issue or maybe manganese? I'm interested to hear what others have to say. I don't think it's septoria. Hopefully it's a deficiency and not fungal.

That's good! The leaf you showed looks similar to problems I've had in the past, but not exactly the same, it's tough to say, but I bet you'll get a response from an old pro here who knows exactly what it is. Quick question: Have you used calmag through the entire grow, or are you just adding it now? Just curious.

Also just went through about a gallon bag of defoliated leaves from a few days ago I didn’t have a chance to dispose of. I can’t find any bugs:/ I DK if that’s a good thing or bad because the mystery continues. Thanks for your responses

I’ve used it through the entire grow. However...

I was using it as one of the last steps in a rez Change.
After talking to some people they said that should be the first thing that goes into my RO water and I was possibly locking it out bc it was basically the last?

not to sure so I did a Rez change and used my sensi cal mag first.

It's definitely hard to diagnose when you have so many opinions for sure. I was having a similar issue. I was using recommended dose for AN and had my lights at proper distance. I cut down my ppms to 800, completely dimmed my lights, and have them 3 feet away. The problem went away. I don't even add any cal mag anymore and have no signs of deficiencies.

My only issue is I want more grams of bud and dimming my light down to 100 watts in theory would only give me 50-100 grams of bud. My temp and humidity is fine, but she starts turning yellow and shows deficiencies when I push the light. I never had this issue with MH and HPS. Maybe it's my LED. I'm gonna try Samsung LM301Bs on a future grow before deciding to go back to MH and HPS.

Hmm. My lights do not have a dimmer option. I’ve been thinking about upgrading to a spider farmer or a HLG.
I’ve heard great things on hps but was afraid of heat control.

Do you think I should take one light out or just let it ride? I am end of week for flower and since I don’t have anything to compare them to buds look fine to me. They are small but are starting to grow every day and you think I should take one light out or just let it ride? I am end of week 4 in flower anf probably have at least that left. since I don’t have anything to compare them to buds look fine to me. But obviously there is a issue. They are small but are starting to grow every day and the trichs and smell is really starting to come out. I just wonder how much better things would be going if I wasn’t having this issue.

The auto flowers are more affected then the photo in my tent?

Your leaves do not look like they are bleaching from light so although it looks very similar to what I had wrong with my plant, I'm starting to think its due to different causes from mine. You sound 100% sure it's not pests so I think cutting back on ppms might have fixed your issue. I would keep the lights and keep your ppms where they are now as long as they stay green. It takes a week or so to really tell if its making a difference in veg, in flower might be hard to tell since there isnt much new growth besides buds, so as long as the leaves don't get worse it should be fine.

Make sure to check ppm daily or every other day as well to properly top off your reservoir if needed and even though you shouldn't have to, it can help to know ph. My nutes sat at 5.8-6.3 during veg, but when I switched to bloom nutes, my batch is always 5.4-5.5 and I have to PH up to 6.

Could be lockout too lol. When I mix my nutes I sort of do the order you did, if using silica, it comes before all of those you listed. I also use a mixing cup to add the nutrient to and then add water from the res to dilute it and mix before adding to the res to mix again. I was told if you add a drop of nute into your res water and you see it make clouds in the water upon impact then you are witnessing lockout.

It so hard to figure out what is factual or just bro science and sometimes what may work for one person might not work for another. I hope you figure out the problem. Just experiment, document what you did, and be sure to give enough time to see if a solution is working before trying another solution so you don't just compound problems. It's better to do during veg, but you gotta make the most of what you got.

Looks like its going to be some good smoke though. I'm on week 3, so I'll be happy if my buds are that big in a week.
