hey im pretty sure this is nute burn, i just went from some 10-10-10 to 10-50-10 for flowering and about a week into it i started getting this stuff, and the leaves at the top are getting a little more brittle it seems as well. and for flushing them out, is there a good time in the light cycle to dump a buncha normal water on them? and should i water every other time with the plant food? or dilute at first and just use it every time

theyre under 4 4ft florescent bulbs btw and about 10 days into flowering

If they've looked like that for a few days and haven't gotten any worse I wouldn't worry about flushing them, they are minutely nute burned there and flushing the soil will do more harm than good (flushing shocks the plant). If it gets worse then worry about flushing.

ok thanks, also would it be beneficial to add a small amount of hydrogen peroxide and molasses to my nut solotution when i water? i been reading alot about people using that

hey so ok, another week or so has gone by, the leaves that had the nute burn originally havnt gotten any worse, but new leaves commin up get a little burned too, but it still dun get worse, are they still just gettin used to the big bloom ferts i switched em too?

In the four years i been growing ive had nute burn three times and each time it started right at the tips and was consistently on all of them.Ive found a very small amount of burn on the tips tells me they were getting maximum nutrients.My last grow netted 76ounces off 7 plants.

hmmm k great so keep the same nute mix im using now then? since thats really all theyre doin, small burn on the tips when they first develop then they dont really get worse once the leaf is fully established, and wtf?! over 4 lbs from 7 plants? u sure? damn
