help diagnosing this problem appreciated.

Fox farm trio, cal mag, silica blast
Temps 75-78
Humidity 45-70%
Lights are 22" from tops,
Lst training
RO water from water mill.


This particular plant showed those symptoms before I Did a flush about 3 weeks ago slowly raised the nutrients to about advised 3 tsp GB, 1 tsp cal mag, 1/2tsp silica blast. Still growing like the others just seems fucked lol. Thought it was mite damage but i cant find any(i have a scope x100) and ive treated with neem oil, and and doing so right now. Any advice appreciated, want to figure this out before i jump to.flowering and these ladies are getting big. Pics attached

Doesn't look like anything serious to me, I think you're good to go into flowering

What's the PH of you water in and PH of run off? Got a TDS meter?

Been feeding at about 6.1-6.3, run off is at.about 6.2, my ppm meter recently stopped working properly, but before then.i was.feeding at about 1600 ppms, then water. Feeding about once a week.

PH seems stable, but 1600ppm? Way too high, you're burning them.

Did you recently increase the ppm? High ppm going in and it's building up in the soil.

I had some yellow leaves below and that lookedblike nitrogen def according to most pics. thats why increased from.900 to 1600 ppms. What do you advise? Another flush?

A decent flush with plain PH'd water should bring the ppm back down to a manageable number. Go easy on feeding and get the TDS fixed or buy a new one.

My cousin did the same thing. Feeding to much (high ppm)with literally no run off. Feeding every other watering and had leaves getting crunchy, burning. Ran a PH'd gallon through the pot and run off was reading well over 2,000. Flushed many more gallon through, PH down to 800 and they pulled through to a decent harvest.

Well bro, pretty soon someone is going to come along and tell you that you have Tobacco Mosaic Virus and then someone else will tell you that cannabis can't get TMV and then get really mad when you don't believe him/her.

Next, someone totally different will come along and tell you that you have broad mites. The TMV denier will return and be super mad and then you've lost your thread. Sorry bro, seems to happen a lot.

Ive done tons of.research and.encountered that aswell in threads, but also from what ive seen, my plants have similar aesthetic issues that were very similar to plants whom.people tested for the virus and it came out negative,.in fact ive yet to find a thread where there was a test.for.positive so i thought it was probably unlikely since the plants seem to be growing really well. Im not sure

Could be the start of root rot

Something to do with the neem oil?

1600 ppm is extremely high. I never feed over 500 ppm or .5EC and plants grow nice and green!
