Okay, here's one. I've got some White Rhino and some Mint and an unknown Indica growing in soil. They are currently in the veg stage, 18 hours a day, under a 1k metal halide. Temp stays steady from about 74f lights off to about 78f when the lights are on. Humidity is about 40% with plenty of fresh air.
They start out looking good and growing like I would expect, but recently, the newer growth is all starting to turn lime green, the leaves are curling under, but not curling and cupping/canoeing like a typical nute burn. All of the new growth is remaining very small and the stems a somewhat purple, while the stalks are even more pronounced in their "purpleness" and are quiet woody. I've been feeding them with a good veg fert at about 800 ppm, but I have a feeling my problem, once again, is the Ph of the soil. Last time I checked the runoff it was only about 6.0-6.2 maybe a bit lower. I don't want to try and just throw more nutes at the problem, and when I first prepared the potting soil I added the recommended amount of dolomite lime to help bring up the soil Ph, but it doesn't really appear to be doing the job.
I also don't want to start throwing epsom salts at it if it's an Mg lockout problem caused by the low Ph (unless thats the best solution). If you think it's the soil Ph that's causing this problem, do you have a suggestion on how to get the Ph up? If you think it's something else, I'm interested on your input about that as well. Could chlorine in the water be locking out something? For the soil I used a 50/50 mix of MG and Organic MG, for what thats worth.
I went to soil over the summer so I wouldnt have to fiddle with the nutes and water like in hydro, but Im getting frustrated with the weird growth pattern. I really need to get these in the flower mode soon as theyre getting too big, but have been hesitant to do so until I figure out whats wrong them. The one unknown plant, which is clearly more indica than the others, seems to be less effected by whatever is going on.
** A couple of more things, the leaves are really ridgy, kind of like a Ruffles potato chip, but obviously not as pronounced. They're not flat and smooth as they started out originally. They also appear to have lost they're luster and look (not feel) somewhat dull/dry, but not crispy. They just aren't nice and green and supple as a healthy plant would be.
*** As suggested by OregonMeds, I started more frequent feedings with fertilizer which has greened them up a bit, but the leaves are still small, curling under and ridgy.
Thanks in advance for your help.
