HELP! Jack Herer in Week 9 of Flowering Turning Yellow

flush and harvest before it gets worse.

sacpirate, Flush both plants?

It looks like the ones that are burned are ruined though. No need to harvest that crap. If you want to still do that you can flush the shitty ones and harvest

no only the shitty sick one bro. its a bit more labor intensive but u can do it. u gotta first remove top feed drip line and raise the plant off the tray/table so it doesnt get any unwanted flood water from the lsd nutes. now simply flush by hand multiple time daily and catch the runoff and discard it. this way u dont dilute the ressy. its not ideal but ive made it work in the past.

It honestly looks like you don't know what you're doing as far as hydro goes.

If you've been running at 1200-1400 ppm what has it been returning back to the res at? Also I don't see you mention your pH anywhere?


My guess would be that you've been burning the shit outta these plants for a while.

I used to use a wilma4 recirculating system with hydroton and I very rarely got above EC1.2 which is around 650ppm at 500scale or around 800 at the 700 scale.

These plants look over fed, and pH could be a real problem due to the deficiencies and burnt look to pretty much every leaf.

IMO I would drop your ppm down to either 500 or 700 depending upon which ppm scale you're using and see if the ppm increases after 24hours of feeding. If it increases then reduce down further.

Are you familiar at all with hydro?

Thanks for that honest, yet hostile, response, jondamon. I am familiar with hydro, but am far from an expert. The pH has been a consistent ~6.0 the entire time, which is optimal for nutrient uptake. Sorry for not mentioning it before. The big issue is I was seeing how far I could push these plants. They were loving ~1500ppm, so maybe you had a different strain that liked 700ppm. The issue here is that I pushed it too far by going above 2000ppm, but didn't realize this until the burn set in and it was too late. And now I"m paying for the consequences. At the end of the day I have to experiment myself to see what the limits of my particular system are, so although I'm not happy about the JH, I'll live and learn. I've cut off the Jack Herer from the nutrient reservoir and am flushing her out. I'll harvest her ASAP... I think I can still get some decent bud from her. Meanwhile, the LSD is still dominating and the nutes are cut back to ~800ppm. I'll harvest her when trichomes begin to turn amber, so at least there's that.

Make sure you check your res after a full cycle for an increase or decrease in ppm.

If it goes up, then cut back on ppm

If it goes down then increase ppm.

IME though there aren't many strains that can take that kind of ppm without it being heavy ppm's in veg.


I was just being honest.

I personally feed just enough. That way plants perform well and you don't get any osmosis happening in the root zone.

No offense taken! I'm trying to learn here. I'll definitely play it more conservative next time around.
