Do you think it will do any good at this point? I'm like 2 weeks from harvest and I was going to completely re-design my room after this grow. I suppose I can just get a couple 5 gallon buckets for these two plants and throw them away after this grow. Damn, I wish I would have thought this out before running to town. I'm 25 miles from the closest grow shop.LOL I think its time for some 5gallon pots eh?
Leaves turning down, edges yellowing and eventually dying out
- Thread starter sfrenger
- Start date
Masp, I checked the ph and it was 6.2 so that wasn't the problem, I checked my tds/ppm and it was at 1400 after I added the cal/mag. I don't have soil, this is a hydro grow. The other plants that don't have this necrosis going on don't have roots that have grown clear up the sides of the 3 gallon buckets and all around the net pots. I can only assume that the roots being crowded have attributed to this problem. I have added cal/mag and have checked the ph, and I have checked the ppm and they were all within specs. Now I need to see if anything changes with the cal mag running through the system. If nothing happens within the next week or so, then the new 5 gallon buckets will be the next step. I just need them to survive and keep growing for another couple weeks. Wish me luck.

All my good vibe to you! sorry I messed up about the soil, sometimes u loose track of things. Btw yor water is currently 6.2? 'coz that would be in fact the issue.
Masp, Everything I've ever read states that you want your ph between 5.8 and 6.0 and the occasional 5.5 to 6.5 fluctuations shouldn't affect your plants. Should I assume that you are right and everyone else is wrong? I did adjust my ph down to 6.0 though after I mentioned the ph being 6.2. It is now 6.0. I did find a big spider mite infestation on one of the Ice plants I had growing in the room. Yet another clone that I got from someone else. What the fuck is wrong with people that they can't control these little bastards? I have a systemic pesticide that I use at early veg that knocks the little fuckers dicks in the dirt. Bayer Advanced 3-in-1 Pest control, Disease, and mite control is the best shit I have ever used. States that it's safe for vegetables as long as it's not used within 30 days of harvest. Sooooo, had to chop one of the 2 clones I have growing and cut off several budding branches off of my extrema ladies then spray them down (minimally) with neem. I will spray them in 3 days again then hopefully that will keep the mites at bay until I harvest my big ladies. This grow has been just one big clusterfuck after another. No fucking wonder weed costs so fucking much to buy. God I hope it gets easier.

What was the yield from the last crop that has shown this? how many grows between were perfect?
When all has changed and nothing has changed the Gardner stands in the middle controlling the change.
I'm not trying to be crass but when every thing does not work the way you want just stop and think of what is the same in all of the issues.
22 ounces on 6 plants, this is only my second indoor hydro crop, so there have been no perfect grows
The only two things left to change are the nutrients and the buckets. I'm changing the buckets and entire grow room to accomodate larger plants for the next grow so we will see if that fixes the problem. If I am still having the problem then I am done with Advanced Nutrients and I'm going to go with FloraNova series.

Yes my friend you and everyone that told you that is wrong. The ideal range for hydroponics is from 5.5 to 5.8, if it rises above 5,8 you have to adjust, or top with water or nutes or however you do it. or else you'd be locking K, Ca and Mn, right the way. And that comes from theory and practice mate
Masp, Jorge Cervantes says in his book (Marijuana Horticulture The indoor/outdoor Medical Grower's Bible, copyright 2006) in Chapter 12, page 299, "Marijuana grows well hydroponically within a ph range of 5.5-6.5, with 5.8-6.0 being ideal."
No disrespect, but I tend to have a little more faith in the guy that wrote the book on how to grow cannabis. Now until I start reading in other places that others are having problems with a ph of 6.2, I will probably still consider that not to be my problem. I really do appreciate your input and telling me about the roots getting stressed. I'm sure that is the problem. I will keep giving the nutrient solution cal/mag and try to keep the ph at 6.0 for another couple weeks. I hope that resolves the problem until I get the larger pots and lines in the room. I can see with the mite outbreak that I'm going to have to bug bomb the room after my harvest then spray all the openings with some serious bug spray.

Nevertheless your plants are crapping out while mine are doing sweet, No disrespect it can also happen to me. I'm not talking about the maximum range but the sweet spot or the optimum proven range that works for everybody. You may consider that in spite of what theory says, your strain could just dislike the shifts, or have a narrow PH range.
It's your crop and I'm just trying to help, you could just say thanks I'd consider it, instead of being stubborn quoting a book I read many years ago.
Cheers.

Masp, if you read my statement, you would see that I thanked you for all your input and agreed with you regarding my roots. The ph is the only thing I disagreed with you about but decided to adjust my ph down to 6.0 just in case. I thought your statement wasn't unjustified and this was obvious by admitting that I had adjusted my solution. I will not give kudos until I believe you are right. I don't agree about the ph but I do agree about my roots being stressed from not draining well enough. Maybe you are just looking for a big ol' attaboy, but I don't give those until I know that's the problem. I have followed your instructions because they can't hurt. My leaves have stopped dying off, but I don't know if that's because of the cal/mag or because I started watering my plants less. Either way my plants haven't gotten any worse. They haven't come back, but they havn't died off either.

Didn't like the outta boy part, I wasn't expecting anything from you, just wanted your plants to grow well, if I'm helping you I'm also helping my self, that's how I roll. I reckon I suck at diplomacy, but if I come back that strong is just for the sake of argumentation not to boost my ego. I also bow my head when I have to and I will if I'm wrong about your plants- Btw I was wrong, it's better to adjust at 6 not 5.8. Get your conclusions from the chart. I'm out. Peace

Hey man, it's all seriously appreciated. I need all the help I can get but have to take everything with a grain of salt. I have never had a problem growing in hydro until the very end of flower. I will try to find some more information, but have decided to just harvest my plants a week early and start the new super lemon haze plants out in a fresh clean grow room with big pots. I will watch the ph and adjust down when it hits 6.0 or there abouts. Advanced Nutrients will make it through one more round of hydro before I decide to switch to FloraNova series.
Holy freakin' shit. Just fired up a nug that I cut on the day I started flushing my plants. This was a small nug from the bottom. I'm speechless. If this shit tastes and feels this good without a cure, then I just can't imagine how it tastes after a months cure. The smell is of lemons and karosene. The taste is incredible. It's like a mixed fruit iced smoothie. The high the high the high.......INCREDIBLE. It came on hard and quick, like two 16 year olds popping each others cherries. Nice mix of body and head high. Definitely more cerebral for me. MAN, I just can't believe how fucking high I got off that nug. God dang am I glad I was watching the trichomes. Couldn't have picked a better time to harvest. Wooo!!!!!!!!!!!!!!!!!!!!!!!! Pictures of the finished crop some time next week.
Wow, I found a shitpot full of seeds on some of the lower branches of these Extrema. I didn't ever see any bananas on them either. I thought I had a new mother plant, but I can't be having seeds growing out of thin air. Will try one more batch from my mother plant before I decide. Here are a couple of pictures.
