Orange/Brown Spots on Leaves - Day 23

[IndoorTropics]

Problem: Couple leaves on 1/5 of my plants just started to show weird orange markings. I just watered with straight RO water. i usually add calmag but skipped this time, as last time i think i got minor N burn on 1 plant (another strain actually). Cant be sure if orange marks were there before i watered or not, really not sure, but definitely very new. The weird leaf formation (PIC 4) is not new and has been there some time and i didn't think much of it before. Prob not related. Just thought Id mention it. Been battling few fruit flies but seem to be managing them well with traps and occasional heavy dustings of DE.

Medium/grow method: 6 gallon local super soil / just did some leaf tucking yesterday first time

Feed: and supplements used: biotabs full range + calmag + DE + rotblock

water source: RO bottled water

Strain/age: Northern Cheese Haze - Mephisto

light used: 300w Mars TSL2000. just yesterday i added another 250w (Mars SP250). both at 26-28". lights 24/0. i only switch off few hours once a week to foliar feed Rotblock.co

Climate: temps between 24-27c. RH - 45-65%.

Additional info: Fan blowing good breeze over them into 1 side open tent. 6" extraction fan and filter. using aircon 24/7. tropical equator climate outside.



EDIT: SPREADING TO OTHER LEAVES QUICKLY AND TO OTHER PLANTS GIVEN A DECENT SIZED DOSE OF CALMAG AND FOLIAR FEED JUST NOW. ANY MORE ADVICE? IS THIS A CALCIUM ISSUE MOST LIKELY?

Here are more closeups of the effected plant and all other plants together.

PIC 6 = northern cheese haze
PIC 7 = chemdogging

Hope everyone had a nice holidays. Can anyone please confirm if this is likely a calcium prob for me please?

The 2x Cheese Haze are suffering much more than the 2x Chemdogging.

I watered with heavy dose of Calmag and then did a foliar feed yesterday.

Brown spots spread slightly since i woke up but not too bad or as fast as it was spreading till i treated.

P.S The tear in leaf in 1st pic is my mistake..

Patterns, locations, and appearance makes it look like they got roughed up and scarred.
Did you do some aggressive pony tail or leaf tucking?

The spots with the silver backing..(3rd pic down, 1st post). those are bugs and most likely why it is spreading. Not to worry too much, i have those kind too. You probably live close to orchards or agriculture. They dont infest, and i dont know how to rid of them.
I dont even remember what they are called. Theyve been forgotten about more or less since they dont pose any much of a threat....
I feel like i should know more. Leme do some looking and see if i can find more info on them.

I honestly dont see a def issue.

Very interesting. Thank you so much!!!!! Thrips description maybe makes a lot of sense:

- Starts with "dry spit" on the leaves.
- turns to orange/bronze spots
- crazy tropical equator climate + i live next to water (behind huge wall)

here are some more pictures from right now. there are now holes in the leaves so something is surely eating me up!!? and it is spreading quite quickly but luckily im around and monitoring them 24/7. trying to figure out a treatment for these now.

I am day 25ish from sprout. I have cold pressed neem oil but it seems this requires several rounds of treatments before being effective and cannot be used on buds so worried if i will have to stop using it then later get problems again and nothing can do then. I have read about Pyrethrins and this seems a nuclear blast option. maybe i should grab some urgently and use this + in the meantime do a neem oil foliar??

Any thoughts? Situation is deteriorating and spreading fast. Can anyone else confirm these are thrips? @Waira @Arthur

Honestly brother, turning a good strong fan on them,not harming, will keep them at bay. Ive always sprayed a preventative regimen so i rarely see em spread except later on in bud if they are present at all.

I spray alternately neem, trifecta, and green cleaner.

Thanks. Now a heavy breeze blowing over them.

I have found some Beauveria bassiana and am going to get ahold of this today. is organic and should work from what i have been told..

frustrating as looked with magnifying glass but seen nothing. the holes in leaves look very similar to these 2 threads below on another forum but nobody has an answer, my affected leaf tissue seems to mostly start out white (like glue/spit on leaf) then it turns brown/orange and with bite marks in places. read it could have been leaf stress from aggressive leaf tucking (possible - did this few days ago first time). otherwise thrips...and maybe some calmag issues at same time due to stripping plant with straight RO water...another option is maybe wind burn? really though?

any help appreciated

HELP! Tiny holes in leaves!

There are tiny holes in my girl’s leaves, I’m assuming something is chewing on them but I haven’t seen any bugs on them. I’ve been spraying them with Neems oil. Anyone tell me what the problem is and how I can fix this? TIA P.S. Plant details: They are Amnesia Haze Autoflowers and they are...
