Rosseting leaves... Help
- Thread starter OSBC
- Start date
Pics man? more info too, what lights-heights/rig/enviro from the veg to bloom rooms & anything else ya can think of, might help. my guess would be light/enviro stress from the little info youve given, but its unlikely you'll get an answer without the relevent info, picture speaks a thousand words.

this may be a dumb question but what does it mean when a leaf rosettes?
*edit* nevermind i wiki'd it
basically like a dandelion does, all the leaves come from the same node height near the ground, is thats what your plants are doing? if so thats pretty weird!

IME the twisty leaves at the new growth that you are talking about is Usually a PH issue or the beginning of, or too much ferts...but thats not always the case
just like that if you never gave em any ferts before and then you shoot em with 900 ppm(1.8 ec) which is pretty much max feeding then its likely you might have given em alittle shock with all those nutes...just a thought

I adjust ph @ 6.0- 6.2. Water and food.They start doing it soon as I put um in the big room they got fed same gh 1/2 strength 3 days before transplant, @ transplant i gave um 5ml rhizo 5ml ultimate thrive and 5ml diamond nectar.. Which ive used manytimes. Maybe the transplant to 3 gal from 5 in pot and going from t5s to hid the next is shocking um a bit?And the half strength gh they got tonite was very little I'm keepin um a bit lite so not to swamp um, want roots to spread.. The stems are strait and leaves r drooping.. I'd like to figure out why.. Maybe low rh? Bout 30% from what i can find zinc def can cause rosetting aswell as calcium.. But I don't see how cuz they are purfect till I put in the big room w hid.. Same happened last run... They grow out of it but it's buggin my why it happens.? Only thing I can think of is I used to use gh veg at full strength 15-10-5 then go to full bloom5-10-15. At 1200 ppm. these two runs I've tried to run the gh chart which says cut in half for soil dtw.. 900 ppmAnd I feed water feed with both
The bunchin leaves aka rosetting.. Is buggin me.. Aswell as the stems are firm and strait with the leaves drooping.. Ya lites are 3ft away now gona drop um after a few days.. Thanks for ur input Joe.. Would u take a look in the infirmary at my other post.. White fungus on rapidrooters in my nft system plants are dieing..
Thanks man
Thanks man

Same here. Seems to always be linked to an issue with pH, which is why I go for a range. I have also found that preference for pH range can be affected by growing temperatures, as when I've seen this occur most often is when my growing conditions are too cold. Have had to work hard to get my indoor spaces warmed up because I only use them during winter.
So, I also see slight reddening of the petioles, this is a sign that phosphorous is not being utilized properly. I've never used any Sunshine mix, so I can't speak to how you might go about getting these issues resolved outside of working to shift pH feeds upwards a bit and downwards. If this were coir I would tell you to allow a broader pH range, 5.8-6.2, and ya know what? I think that's what I'm going to advise here now, let it range down into the mid-5s, see what happens.

Looks like a def pH problem....too low in my estimation. I'd feed light nutes at 6.5 once and look for improvement. If not getting better, I'd grind up some dolo lime real fine and use .5 TBL per gallon to drench them with lots of runoff.

What is the proper ph for sunshine#4 .. I normally run everything at 6.0 to 6.2 some say go 6.5 and others say 5.8 or lower! And is it a good idea to add 1 tsp of dolomite lime per gal of soil ? To buffer the soil ph.. My understanding is the lime is ph 7. And it will keep it from rising past 7 and buffer the soil in general to keep it more stable.. Is this correct..? And what are your thoughts on gh dtw feed schedule? I have had good results running the hydro schedule in sunshine at 6.0 to 6.2 no lime in sunshine w a feed water feed schedule.. It seems since I have went to the dtw schedule which is half the strength of the hydro iv been having all sorts of issues.. Ya think the half strength is not enough nutes to keep um strong and healthy??

and again from over watering, and if feeding every 2nd watering then i would not go over 900-1000 ppm max for large heavy feeding plants
i dont go over 700-800
if only feeding once a week (feed water water feed) then 900-1000 ppm is okmaybe higher dependingon size of plant andhow the individual plant can handle it

Definitely do NOT use such cold water, it needs to be warmed up to at least around 65*F for proper utilization. The room temps you're reporting are not out of line, IME/IMO.
Dolomitic lime is different from things like hydrated lime, which I believe drives pH down. Dolomitic lime definitely not only drives pH up, but helps to keep it up via its CaCO3 & MgCO3 (calcium carbonate and magnesium carbonate, respectively), both mineral compounds make water alkaline, as in resistant to pH shift. So what it will do is buffer the pH UP, not down.
As for the plants, the first two look as though any one of the following could be the problem, but leaf turgor is the real test/proof here. Underwatering--leaves will be limp and have no turgor. Overwatering they may be limp, but might not be (i.e. will have some leaf turgor). The other scenario where I've seen them being held downward that way is when conditions are just too cool, but the temps you're reporting would make me tend to discount cold as a possibility, which puts us back on over- or under-watering.
The last plant is right on the edge of being overfed, but it looks pretty good to me.
Many people forget that leaf appearance, as in angles they're held, tacoing or canoing, folding, etcetera, may be a response to ambient conditions with specific regard to temperature and relative humidity. Look up vapor pressure deficit in order to gain a better understanding of what I'm talking about.
