Spots, Help!

Please help me. I can't tell exactly what's going on with my plants only one is having issues right now.

I'm going in FFOF soil only and using the FFOF trio nutes and molasses. I am a little over 4 weeks into flower. My water is R/O with calmag and nutes is probably about 1000ppm including the molasses as well. I usually PH my solutions around 6.3-6.8 and I wait until dry to feed/water. The topsoil started to look a little old and really dry so I added a fresh layer of FFOF on top yesterday when I watered with plain water and molasses. Hopefully that reintroduce some healthy organisms.

Yesterday before I watered I saw a lot of spotting on one plant and need help figuring it out. I've been in a forever battle with nitrogen toxicity due to this super hot soil and I do plan on doing a big flush next watering to release as much salts as possible.

Wish I could help but not sure what’s wrong.... just try to improve conditions and let them grow I hardly put much nutes anymore .. bump!

Consider using Lucas formula. Sufficient nitrogen using it especially during flower.

Looks more like a bug or fungal issue to me. Holes in a couple leaves.

Sounds like you might be overfeeding a tad too but if it were a nute issue then a lot more leaves would be involved.

Look good otherwise.

Checked for bugs. Don't think there's any from what I see. I'm kinda rough with my trellis net and moving the plants around so it could've been from that. And it's only on that single plant out of the three. I did gave my fan really close to that plant so it could be wind damage as well.

Neither banging around or wind damage is going to make spots like that. Did you do any foliar feeding maybe?

Not a deficiency issue at least and a couple of bad leaves does not a problem make so I'd just watch it's nothing that spreads and carry on.

Good luck with it!

No foliar feeding because I was always scared of burning my leaves. Haha. But I'll monitor it heavily

The grow I'm doing now is the first one in two years that I wasn't battling mites and they always won. Horrible pests but not a bug to be found this grow and I'm in the 7th week of flower with a dozen plants of 6 different strains.

I never spray my plants unless it's to battle bugs. Good roots and good food give them what they need imo.

Hoping to pull a couple lbs of these girls and not looking forward to all the trimming.

I think I may have a nute lockout due to soil PH. I used. Soil meter and the PH looks to be around 7. The spots I think are getting worse. I think it's a P Deficiency

I think I may have a nute lockout due to soil PH but I dont really know so I shouldnt do anything based on that information since , well I dont really know. Fixed it for you.

Maybe back off on the nutes to 7-800 ppms cut out the molasses till last two weeks of flower and then use just a little if doing so, which is just to feed the microbes. Oh yeah get some microbes.

I get these spots sometimes I think it might be molybdinum (spelling) but I dont really know but stay the course and just monitor it. If everything else is ok you will get through this.

Microbes are your friend.

I didn't say I was going to do anything I was just making an hypothesis to what it could be. But yes I'm going to be watering with plain water for awhile

My spots..Which is a deficiency due to me not changing out my water and adding fresh nutes. Not worrying about it as they are in veg.

You need the microbes and I would feed water feed water or something just watering for "awhile" is not what I would do. And in flower no less. unless I was in the flush stage. then it would be just water some molasses and microbes then the last week it would be just water or something close to that .

What microbes would you recommend?

RAW brand bloom, use it in veg and bloom. Very little like an 1/8 tsp per gal once a week. / maybe a heaping 1/8 tsp once a week

Then when you get to the flush stage (if you flush) you will have a microbe population and not really necessary to use it in the final weeks.

If you use the Fox Farms Trio you will be constantly killing your microlife with the chemicals. The Big Bloom is organic I think, so that one wouldn't hurt them.

how is that

Big bloom is the only fully organic nute out the trip. He's right about that. Now I don't know much about microbes but I did read that the other nutes do kill the microbes over time because they're synthetic salts and you'll have to replenish them by top dressing more potting mix or just the microbes alone.

Right now I'm using molasses to try and feed what microbes are there now in the soil.

You should check out "Teaming with Microbes". I read that and learned a lot, and he explains it way better than I ever could. It's around these sites. Armyofsprout's right about the salts building up. You couldn't live if there was too much salt in your body either.

EWC tea is great to add microbes too. But if your soil is full of salt buildup, they might not be too happy. Even just top dressing with some EWC adds goodness.
