Plant Moisture Stress - Symptoms and Solutions

Ya thats what I figured thanks, already read page one and most the others. I'm pretty sure over/underwater isn't an issue but i have real low humidity so I'll try to fix that thanks again
 
Also, UB, thank you for welcoming me to RIU! i'm loving soaking up the info like a sponge... or plant ;D hope all is well. We have officially topped and trimmed some bottom stalks, and now, the long wait... and hard work to keep it all right. I'm very excited and a little nervous as the process is new, but it's looking great. I'll post a few more pictures, maybe you can take a look? Also UB, i hope you weren't offended by my attitude towards you're bluntness. I do appreciate it, no matter if i dislike what i hear. I think I can learn best from reality, not some inflated ego stroking... I do hope we can continue discussions! Thanks again for all the help, and i say this from anyone who hasn't thanked you, because you religiously check the forum, and respond accordingly. it's a lifesaver to the newbs biting their nails over nothing, and anyone else in between.... Thanks again UB hope to hear from you.

unsure if this will even get a reply but can someone look at these pics? https://www.rollitup.org/members/fr...e-kush-grow-picture114229-overfertilized.jpeg
i'm doing a coco/hydroton grow with Purple Kush clones, and I have a feeling they're over fert and overwatered, so what i did was i flushed them with 6.0 pH water at 10-50ppm for a couple days until the runoff water read 650ppm and 6.0pH...

What lead up to this? What was the EC you where using for the last waterings leading up to this?

How often do you water? I've used both coco and rock wool but never together. I usually mix perlite with coco and even tried with hydroton. I've switched to soil for everything.
 
Been doing some reading, and it sounds like this is probably my problem.

I'm just an occasional bongsmilie person, don't really know anything about growing. This is the first time I've experimented with it, found a single seed in the last stash I had and decided to plant it after leaving it sitting on my desk for a few weeks.

Leaves started pointing up after a few days, then curling a bit as you can see in the photo, and reading through this thread I'm guessing maybe overwatering (I've been pretty careful not to) or low humidity or something? I dunno though, I've been poking around through these and other threads looking for something similar in photos, and I haven't seen it. maybe one of you cats can confirm for me. Hasn't really grown much in the past few days either, it's about 8 or 9 days since it sprouted.

What type of light is that plant getting? I pulled a seedling somewhat similar to that out of a tub of soil. It had been in there dark for at least 3 days. Its cotyledons were standing straight up like yours, and it was a very pale green/yellow color like yours.
 
Two 5500k 100w equivalent CFLs about ~2-2.5 inches from the leaves on ~18/6 or so. About 3500 lumens between the two, I think. Not enough?

You only have 46 real watts of light here. You're going to need more. Check your home depots for 65w cfl's. 42 is the lowest I would go if they dont have that. Two or three 65 watters should get you on track for veg. You may want a bit more for flower though.

Thanks, I appreciate the info. I was worried it was something more problematic.

As long as you're not inducing moisture stress and you have a normal root system, low RH should never be a problem. The root system will compensate for the "extra" transpiration rate by taking in more water, it's an internal cell turgor thingie, a balance based on supply and demand.

We water by hand once a day, now. We went from 3x, to 2x, to now once per day. We jumped from around 500 to 1000 or more PPM which I think burnt them. We just flipped to 12/12 and are weaning off Veg Nutes, going to Flowering Nutes at around 600 and then pumping upward to maybe 1200 we will see what they can take. Also think overwatering might be an issue now, some algae grew, which is an indicator, and some leaves are still cupping.

Light is on for 18 and the table is fed 8 times aday.. "3".. Here is my mix General Hydroponics FloraGro 2-1-6.. FloraBloom 0-5-4... FloraMicro 5-0-1... mixed at 2.5ml to 4.5L with a total of 35 l in the Tank... 4" netpots with a mix of 95% dolamite and 5% Hydroton... PH has been 5.5--5.7--and 6.0

These little girls are White Rhino and they were cloned in a easy cloner... All was good untill the move to the table... 1 week old in the table now and plants are anywhere from 3" to 9 " tall... ok now the bad.. I have been acting like a new dad with this setup so this is why I need help..
Here is a scan I took of 2 of the worst leaves, I can take more pics if needed..

Thanks for the help and I look forward to a responce..
