Whats causing this necrosis on leaves - plant doing fine otherwise..bugs vs. Ph

She's an kush variety that showed her first signs of flowering last week. Shes's a beaut, about 4.5 feet, but wtf is wrong with the leaves....

A month ago, the plant was stressed in veg for about a week due to ph, the necrosis showed up then went away, i thought i fixed it but its back and now on the vast majority of the leaves. The plant is still growing beautifully, but the first time it got stressed it stopped growth all together for a full week. Now i am just trying to keep my baby healthy....

Im thinking ph problem again or bugs..... Not too sure....

Has anyone seen this before or knows what it is??

Looks like bugs to me, but I'm no expert.

looks like a nute deficincy or burn to me as all insects I see eat the leaves from the edge towards the center

This is definitely bugs. I've seen this many times in my outdoor grows.

Mist it down heavily with a strong mixture of Dawn dishsoap and water a few times per day, rinsing with plain water after 30 minutes.

If that fails to work, you might have to go with something a little stronger (unfortunately). I've *never* used any chemicals to cure bug ailments, just the above mixture and for really bad infestations, spiders and ladybugs (which can both be bought online in bulk for cheap).

Edit: out of curiosity, can you snap a couple of good pics of the bottom of some of the leaves?

Ya I'll get a few more pics. I'm starting to think it's being caused by ants or something eating the roots..

Bugs for sure. Something is eating ur baby

bugs, some do poke holes in the leafs and not eat like a rabbit . 100 % sure. get some spray asa fucking p

Yeah deffo something is eating them - those leaves are being munched on for sure. Is no nute or PH problem, etc at all.

Unless u managed to identify which insect it is & bought a specific spray, then i'd also agree that Spek9's washdown sounds best idea to me at the moment. If u leave it unchecked then until some other environmental factor kills the bugs, they'll likely just keep eating.
