Update , it’s spreadingNow then brothers, I have an issue. Yellow spots on old leaves, should I flush with water? It in flower, pre flower? It’s only on about a dozen leaves.
help me . I’ve given it a 1.1/2 litre flush of ph 5.5 water. Now what ? Hey you guys 
I think it’s either , cal overload or N, the worst leaf. Oldest growth , soil ph 6.1, temp 25/30 c, humidity 55/70, . What do I do?
Got nine autos in tent it’s the only one in pre flower only one with yellow spots. I’m thinking it’s either cal or mag or n. Rox . Just fishing for opinionsAre these bugs?
Looks like bug damage, but I'm not 100%.
Hope you get it figured out

How's their calcium? What kind of medium do you have? Nothing tiny going on underneath those leaves? Inbox me if you'd like to discuss her moreRust spots in 2/3 week flowering. Bad /ok/ good ? What to do ?
Soil/coco/perlite, equal mix. Humidity 50/80 .Biobizz full range daily as recommended , rtw , temp day24/30, night 21/24, 20/4 cycle, s/f 1000x4, 28” above. Some pests little flys n something black a bit bigger look like Beatles not a lot but some . Epsom salts once a week with bat poo . I do put cal/mag in every 2/3 days. Have looked under leaves no critters stuck to them. I do have a couple that look half eaten. Ph in 5.8/6.1 out 7/8 . Tent 4/4/6 c extraction ,
spray with neem tonight, just in case , First time .got nine in tent only one with problems.
I would avoid using neem while flowering. Might want to look into Safers soap, or a mix of alcohol/water. Not really good to be spraying anything while in flower, but some are a better option.
Ca lockout from excess P(the spotting). She looks overall overferted. Overly glossy leaves with clawing indicating nitrogen excess. I know how damage from thrips looks and it's not that.Rust spots in 2/3 week flowering. Bad /ok/ good ? What to do ?
Exactly what I’ve been treating it as, . Always good to get a second opinion. Thanks . You have I helped immensely. Was about to do something risky. But now I’ll give it a day or two, see if it comes bk round.
although uncertain, I believe you may have a nutrient lockout of potassium. N-P-K are all mobile nutrients. If the deficiency starts at the bottom of the plant its a mobile nutrient, top is immobile. Ph water to 6.4 before application. The plant can only absorb nutrients in a specified ph.Update , it’s spreading

I agree with the lockout... Possible from inadequate ph (you said 5.4, raise to 6.4) or overfertiization . Having nutrients balanced is just as important as the ph level. An abundance of one nutrient can belittle or throw off another. Think of N-P-K just as you would the p-h-level. The plant will grow substantially better if those values are kept in check, Ph and NPK
I it lockout. Keep doing it . I just forgot again. Living Groundhog Day. It’s hard work having the short term memory of a goldfishI agree with the lockout...
