Leaves going crispy from bottom up

[SchmoeJoe]

Hmmm going to have to do some research. I run a hydro store and give advice a hundred times a day i cant pass on knoledge that i havent verified. Honestly not saying its wrong but it just dosnt sound right. Thought a seeds genetics were pre determined before they even pop. Thats what makes fem seeds possable. Fem dna+fam dna= fem dna
Poped 100s of fem seeds all into solo cups for first pot. Never a male or even a hermie

It of course wouldn't cause a properly produced fem seed to become male. There's no genetic potential for it. There are a number of things that can influence sex in regular seeds. On page 20 of Jorge Cervates' Growers Bible he stated "Environmental factors start influencing sex the moment the seedling has three pairs of true leaves (not counting cotyledons)". The section then goes on to list a number of factors that can influence sex in either direction. It was adapted from the archives of Dutch Passion Seeds with the permission of the owner, Henk.

I can't find the article about the taproots bottoming out causing more males. I know I've read that but it isn't in the books that I currently have. One of the things listed from Dutch Passion is "any environmental stress" which would definitely include becoming root bound. Cuccuberts, if I'm spelling that right (melons,cucumbers,etc) will die if they're allowed to bottom out. Transplanted trees can die if they aren't properly lined up with the soil level. These are obviously just a couple of examples and there are sure to be plenty of plants that aren't so particular but it's definitely not so far fetched to think that restricted roots in a young plant is an unnecessary stresser that will potentially have a negative effect on the ultimate genetic expression.

Of course I wouldn't expect you to pass on second hand info without verifying it. I wouldn't have even mentioned it if I hadn't read it in a credible book. Of course not being able to find it isn't helping my cause.

Fem seeds are possible because some plants don't have the male chromosome. The pollen fron that plant wont contain male chromosomes either so neither will the seed. The reason that some people get males and hermaphrodites in packs of fem seed is because some seed producers don't go through process of eliminating the plants that have the male chromosome. In other words, as I've already said, properly produced fem seeds won't be effected at all because they are fully female.

A lot of female plants from regular seeds will still have male chromosomes that can be expressed in feminized seed made from it. If you've done hundreds of your own fem seeds without males or hermaphrodites then they were either from properly produced fem seed to start or you've been lucky. As far as never having had this issue with solo cups, how deep are solo cups? 4 inches? 5 inches? More than 3 for sure.

youre a savant heh,

A savant is naturally gifted and able to pick up their particular skill with little to no effort. I've been putting in the work studying and practicing growing weed and plenty of other things since the 80's. If you're going to try to talk shit at least make that what you're saying makes sense.

Can find no information on stress causedon tap root root binding causing male plants. Keep in mind the grow bible is way outdated and writen during proabition. Little real study has been done untill the last 20 years and even now it is restricted in most states. The jurry is still out. Looking at many posts abought the 16 oz bear cup challange i see no evidence they posted abought more than normal male plants caused by afore mentioned root binding stress. Back to the sick plants i to would start fresh. By the time they are healthy new sprouts would already be past them if dont correctly

 

[Dynamo626]

Will keep in mind if i ever plant non fem seeds.... Ha never gona happen lol. If it happens ill plant into half gal instead just in case because yes it is easy not to over water. And it is also silly to use cheep soil for such a large investment in time and electric when the difference in price is only 15 bucks a bag at most

I haven't been able to find the original publication where I read it either and I always tell people to treat a lot of what they read in the older books, and even a lot of the newer ones, with a degree of skepticism.

That said it is a standard in practice much pretty every other field of agriculture to make sure to minimize stress during the germination and early veg periods. It's pretty much the same as how people who go through significant physical stress when they're young will likely be impacted later in their adult life. As an example I've never heard of anyone but weed growers starting seeds in paper towels.

How do you feel about stress in general? 'i bet youse analyse stuff'

Oops not now.

um.. first of all. what is happening in this thread? Second. Still haven't figured out my problem from any of these posts. the weird thing is, i have used this same setup, same soil, same techniques for a long time and never had this problem before. I've thought that maybe the soil I usually buy from canadian tire is different than it used to be. it's just cheap soil, and the most recent purchase of 20 bags or is when i started to have this issue. some plants made it through and once they went into the flower tent they were fine. I only had a tiny fan in my veg tent at the time, but my autos are in that tent and they all seemed to do fine. I've also noticed with this new batch of soil that some of my plants are growing warped ass leaves. like twisted leaves. maybe the ph of the soil is all out of whack? I should test it. I have plenty of seeds that I have bred over the years, but this particular batch is a blueberry cross i was hoping to breed so i really wanted to figure out this issue. Wanted to cross that blueberry into my nypd, green crack, and chocolate haze.

Lots of tangents in this thread, for sure. It most likely is lockout from the ph being off. If you don't have a soil ph tester you can use a regular pen or test strip using a slurry of the soil.

Does anyone know what this spots are? This is a white widow autoflower in DWC, it is about 18 days old and these spots are working there way up the plant taking over. I have changed my water and I am using GH 3 part system with cal mag, for each gallon I added 1/4 tsp of micro, grow bloom and 1/2 tsp cal mag. The water was ph at 5.7 but does drift up pretty quick. At first I thought I had a cal defenincy but seems to be getting worse. I started to think it was rust so I got some sulfer based spray called Defender and this also is not helping. Any suggestions? Oh and I have a northern lights in soil rite becide the white widow and has no issues as of yet

Sorry buddy, didnt mean to troll you,
You should relax though.

 

[Dynamo626]

twisting leaves is a sign of ph being out of wack. never had the problem before. i blame the cheep soil. maby got a bad batch. cheaper products usually dont have much in the line of quality control

All I've been doing is laying information. You started off by calling everyone in this thread bots. Then you specifically started calling me out with sarcasm.

Trust me, I'm relaxed. As an emotionally mature adult I'm perfectly capable of calling out a jackass without raising my pulse.

Lol yea get it all out of your system man.

I understand fully where Ludi comes from. It seems like if you ask a question on this site, or any other, the people all come in like they are experts, but all they know is the common knowledge that can be read about or found out on the internet. Everyone is too busy riding their own egos and acting like experts. Rarely though do I ever get a problem like this solved. If it ain't on the menu, well we don't know how to cook it! I find this with life too. Everyone's so smart. everyone's so good. big ego syndrome. There is very little honesty and sincerity in the people's personalities. Every person you come across is just a bot. A factory made assembly line dufus. Fist bumping you and calling you bro, jumping on the latest trendy bandwagon. Tattoos, fruity hair cuts, coffee, bacon, screamo music, wiggerism, just to name a few. don't forget retro converse shoes and 80s style green sunglasses.

I appreciate the responses don't get me wrong. None the less, my problem was not solved, even though there was a slur of information given. I realize that Ludi may have struck the first blow, but to swing one back make you no better. "But mom! Davie started the fight!"

Just felt like I wanted to point out that Ludi might have been referring to that sort of thing with his "bot" remark. If he/she is, then I fully understand.

in either case. bickering and shit is just lame. we are not children. no need for that. I don't mean to offend anyone. There was a lot of interesting information given from various people.

I've ordered some coco coir, and I'm going to go with that and see if it solves my problem. I'm so sick of buying bags and bags of soil anyways. its ridiculous. I live in a small town too and people know me and look at me strange when I buy 20 bags of soil in the middle of winter xD

With regular seeds it matters more about seedling and veg temps than the length of the tap root...

Also please get rid of that soil or at least add A LOT of perlite on the next transplant. It almost looks like its clay.
