Deficiency? Pls Help!

I agree with @highaltitudeorganics, put nutes aside and yes it looks like pest damage check the underside of the leaves as well, I think it might be Thrips or White fly I had this exact same looking symptoms a couple of weeks ago and it turned out to be pest.

It's too much.. It's like a crazy amount of growers use too much.. Cannabis does not require crazy amounts of nutrients.. It likes light.. And water that's what does a lot of the magic.. The nutrients get absorbed through intake of water.. Light is probably your biggest problem. You lack light.. Your plants are fairly tall with a lack of outward growth.. Get some more lights or improve your lighting situation. Your buds will finish small and your final weight will be low mostly because of two things.. 1 you are using too much nutrients and the big number 2 your plants need more light.

We are looking at thrip damage here guys...nute inputs aside.

You need a ph and tds tester so you can feed your baby at the proper ph and tds. I always check runoff values coming from the bottom of the planter, that tells me what I should be doing at the top end. Lockout happens with to many nute or improper ph. Defficiency happens when not enough food. Checking your runoff water tells you what the plants have available to them and checks the ph in your medium.

Lay of the nutes man.. your soil is packed with with it... More then it needs. It will slowly need less nitrogen also so don't feed it anything anymore. Otlr your be left with the impression that otherthings are wrong and get in trouble. unless its potassium i would had anything . Even then. I would let it ride off

If your ppm were at 2000+ not to long ago i really dont understand why you would even top dress at this point... Like do drugs mention what you have is an excess. And what caused it was your adding of to much water solube phosph... And this cause a calcium lockout du to improper balance... Little more often is better then more everynow and then... Thats a lot of table spoon. 2 weeks ago your run off was very high remember.. you are in soil not hydro... You flushing your soil won't reduce may reduce salt nutrient and solube ones. But the thrut is that all that organic nutrient don't show up much in ppm reading becaus they are not salt.. so if your ppm are at 1200 not bad but yiu have to remember that they are boosted by all that topping that dont show much.. so your nutrient are way above what the plant need in phosphorus. Nit much to do other then lower phosphire intake. Since you are more likely going to creat other probleme trying to re equilibrate this and the damage you see will never heal... You can rinse off if ppm is wrong and give a more alcaline water abive 6.5 7+ for one watering which make magnesium and calcium more availlable then lower ph below 6.5

May be too much nutrients, you are growing an autoflower buddy, these require less nutrients so the dosages you are feeding at along with the top dressing are making them have a K(potassium) overdose wich can cause other nutrients to lock out. If you top dressed, stick with water for a couple waterings and see if they get better, increase the little bit the water volume to make sure there are no build ups, and if you decide to usr bloom liquid fertilizers, just use minimal ammounts since you already top dressed. but May also be just calcium deficiency. Where exactly are these symptoms showing, from the bottom upwards, or starting from the top? Stay lit growmie.
