Nute Burn?

I had pests (thrips & leaf miner) but they have all gone now, after a couple strong feeds i got sum yellow burn spots & leaves curling upwards at the tips...

Is this nute burn?
Im hoping it is as im 99.9% sure ive got rid of all pests!

Thanks in advance...

Someone please check out the second picture...whatever it is its spreading fast!

Im thinking nute burn from micronutrients?

Are those tunnels? leaf miners coming back?

Back off your nutes? flush your medium?

do you foliar spray?

Def not leaf miners coming back, no folair spraying apart from organic pesticide when the lights are off

Im 99.9% sure its over feeding, should i just feed plain water next time or will it okay to just give light nutes?

if you think you're burning them then back off the nutes completely. Flush the pot with 2-3x the amount of volume in clean PH'd water. Then wait and see if the new growth looks healthy.

If you think you are burning the plants certainly don't continue to add nutes.

Cool thanks, i havent even PH tested my water yet cause supposedly Bio-Terra doesnt need it (organic medium)

Im gonna buy a PH tester 2mro out of curiosity to see what my tap water i like after i filter it, should i get anything else at the garden centre incase my PH is too high?

Thanks guys..

pH test the runoff after you water. pH up, and pH down is what I have, but I wound up not needing it. Definitely do a flush of 3 to 4 times the size of your pot. ie. a 1 gallon pot should be flushed with 3 to 4 gallons of water.

Ok i got one plant in an 11ltr pot, so i should flush with 33 liters of plain water!?
That sounds so insane, what about overwatering?
Surely half my soil will be washed away, roots exposed etc...

Getting 33 liters of water ready is gonna be a bitch & im gonna have to take the plants into the shower or something, my runoff trays arent that deep lol

I appreciate the advice but i think im gonna just water with plain water, back off the nutes for a week...ifit gets too serious then ill flush
