Please help: rust spots, holes in leaves

What is the temperature and humidity in your grow area?
The spots look like it maybe calcium deficiency, Image are quite blurry.

Hey sorry about the issues... Are you growing in soil or other? I grow in soil and I had the same thing happen to me...I checked no bugs...pH was relatively correct and after google and chatting here it led me to the roots.....I flushed and then let dry dry...like super dry before next water or feed and started using hydrogaurd for root health. It seemed to help correct my problem.

They look like they are hungry for everything to me, esp K, CaMg & Micros as it is affecting the entire plant, not just tips or lower leaves - brown spots are often a sign of K def, which interacts with CaMg
Maybe drop the pH to 5.6 allow it to drift up to 6.0 and add a drop of H2O2 just to make sure the root zone is clean and well oxygenated
Whatever you do to rectify the problem, the tips will perk up first so that's your indicator as to whether you are improving the plant/rootzone or barking up the wrong tree

might want to revert back to veg lighting hours until you get her back to the peak of health.… nothing good happens when you initiate flower on a chic thats already weak or compromised.
but to really help we need more info
What is your grow media?
Did you amend it with anything?
How often do you feed?
What nutes are you using?
Do you have cal-mag?

I firmly support what @Phytoplankton brought up. Go back to the vegetating stage ASAP and fix the problems. It might take 2 or 3 weeks but that is not all that long for two reasons.
One is that you have already done 9 weeks so what is another 2 or 3; especially if that extra time means a healthier and larger plant.
The second point is that once flowering starts it is pretty much to late to fix problems, especially ones concerning the growing of the plant itself. These problems will mean a smaller harvest and the quality will suffer.
I do not grow with a hydro method even though it interests me. Maybe some of the other hydro growers will know but I think that if the pot was filled up with more of whatever the roots are growing in then the plant has a larger root mass. The roots are where plants store a lot of the extra starches and sugars they need. Plus once in flowering the plants tend to slow down the development of new roots so what they have when the flowering stages starts they pretty much have all they are going to have.

I realized there were holes in the leaves a little over a month ago. I sprayed Neem on them for a few days I wasn't sure it was helping so I sprayed 3 n 1 garden spray on them then insecticidal soap for a few days. It's safe to say the foliage was wet for a while could this be rust fungus
@Rexer @West Hippie @Verbalist @LKABudMan any thoughts? I'm with the masses that there are multiple issues going on and that going back to veg is the best idea.I realized there were holes in the leaves a little over a month ago.

I wish I could personally help with the Hydro system but I am also unfamiliar as I am a soil girl.
It does resemble rust fungus to me, thinking some insect issues you may have had earlier on along with a need for K and Cal-Mag.
Do you have/had humidity or heat spikes in the tent?
curious about that as well. i'm wondering how the roots are doing.
@KapnKush -- we would like to know if you are dwc or rdwc, or a passive hydro set up. calling something hydro is very generic now. it covers dozens of differing grow styles and approaches.
then lets see a pic of your nute line up. flora runs as a 3, 6 or 10 part system. plus you will need calmag and maybe an enzyme cleaner. there's a good chance you are missing crucial parts.
Hi @KapnKush
Everything is salvageable from what I see. But the more info you can send, the better we can help. And I will add my voice to revert to veg, get the plant back up healthy, then transition back to flower.
The water temperature for your reservoir?
Any root protection additives? (Hydroguard, Z7, etc)
Can you tell us how your mixing your nutes? And in what order, include everything please.
Is it possible to show a picture of the roots?
Any chance that water/nutrients have been left on the leaves?
And what PPM/EC is the reservoir at right now?
PH fluctuations, I see your running at 6.0. While that is in the range for some nutrient absorption, it's not ideal. Unless specified to do other by the manufacturer, PH to 5.5, let it drift up to 6.3 before resetting. It's important that the PH drifts to allow your plant the ability to absorb its nutrients within a range, if you look in my signature, you'll see a link on PH and hydroponics, it'll explain the importance.
Don't rush to make changes yet, your instinct will say "do it", have patience, get the required info, then take the actions needed.

I'm sure there's a lot of great people on here it can help you out looks like you need to get it on a good feeding schedule and check for any critters do like I did move everything out of your tent wipe it down with bleach let it set 24 hours and then spray it down with some hydrogen peroxide let it set for 24 hours then move your plants into a happy tent. After you find someone on here who will hook you up with a good feeding schedule I would first flush them. And then introduce nutrients as soon as you flush. I would also clean up that undercarriageTried many sprays nothing is working and I don't see any bugs
Same here as far as growing in soil.If it was a soil grow the usual recommendation would be to start with something along the lines of a Cal-Mag product and something that will boost the amounts of Potassium (K) the plant is getting.
My guess is that the holes and missing chucks of leaves are definitely an insect problem. Since it does not look severe there is a good possibility that something, maybe a caterpillar, chewed some pieces of leaf or ate the holes in the leaf, and then formed the adult insect and moved away. I have had that happen several times on my outdoor plants.
I did a google search using the search term Rust Fungus On Weed and there were several articles that might be helpful. Rust Fungus usually does not affect a plant until it is into flower. Try rubbing some of the brown spots off with a white tissue or cloth. If it rubs off there is a good chance it is Rust Fungus. If it does not rub off then time to consider that there is a nutrient deficiency.
As mentioned it is easier to fight these plant problems while the plant in still in the vegetative stage. Once it starts into flowering we are faced with treatments for fungus, mildews and molds that might not work as well or will cause damage to the flowering buds.

What size pots ? Are you using LED or HID?Tried many sprays nothing is working and I don't see any bugs
