What's wrong with these leaves? Bugs??? (PICS)
Comments (1)I think your assumption is correct. If you overwater even once it seems, some leaves will curl - nature's way to give you a clue! The curling is usually on lower leaves and they will remain curled. So long as you are not continuing to get more curling, you are probasbly fine!...See MoreWhat's wrong with my Mango seedlings?

Comments (7)I'd live with the curling just fine, the burning of leaves is my problem, because they fell afterwards. You can see the top 2 pics and how the green color is turning to black. I'm almost pretty sure now it's spiders. We have plenty of them here, and I've crashed at least 5 tiny ones today, I've found them hanging from the leaves with their strings or whatever that thing is called. I've used all sorts of soil. Sandy one and I mean just sand taken from clean sand-dunes, sand plus potting soil, pure Ukrainian potting soil alone, and sand plus clay plus potting soil...etc I've started to give them an organic fertilizer and spray them with a pack of minerals. At the beginning I made their pots drench with water just to fill in any air in the soil, as I used to do with the citrus seedlings, but it seemed that it was a huge mistake. So far everything is in pots and not in the ground, because I live in an apartment, and the piece of land to be a little farm for my experiments is still a barren land and has no wind cover, which will be deadly during the summer and the coming autumn. The temp hits 45-48ðC in the summer, and 12-18ðC in winter. At night in winter it drops to 0ðC sometimes but not for long, and if it's a barren land than a -2ðC has been recorded. Also, winter is really dry here, and even the summer of the last couple of years had been dry as well. The pots right now are in the shaded balcony, and the temp there is around 27ðC, and I don't think they're hardened enough to be fully exposed to our harsh weather. Looking forward to hear from you and your experience....See MoreIs there something wrong with my tomato leaves (pic)
Comments (7)Yes it looks like some sort of contact burn like some spilled fertilizer of something. But the rest of the plant looks fine so a few damage leaves are no problem. Within a month or so you will see all sorts of leaf damage/spots develop - it's the nature of the plant getting older and the weather - but most are no serious problem and fruit production isn't affected. Go easy on the fertilizers until it blooms and begins to set fruit. Then give it a good feeding and then back off again for a month or so. Too much fertilizer is worse than too little. ;) Dave...See MoreWhat is wrong with my Dahlia? (Please see photos)
Comments (10)Are you seeing any positive effect after spraying the Neem oil? This is a serious infection! I can see the webbing on the first image, now that it was pointed out. I've never seen it this bad. Here's a post from a dude on a 'roll Em up' site about growing pot, (amazing what dahlia growing tips you can get on those sites!) which has very interesting commentary on fighting mites with Neem Oil: "so here are a couple things about neem oil... i use it and swear by it so ill give you my personal experiences with it...first i've used neem oil under HO satellite IV floros on a 24/0 crop with NO problems.. i didnt have any burn from the water or the oil magnifying light... no ill side affects at all.. so if you are using floros i would venture to say you'll be fine spraying during a 24/0 light schedule... just move the lights when you spray so you dont spray the lights themselves... make sure you get under the leaves and the "inside" of the plant just as well as the topside of the leafs and "outside" of the plant... like was said those little bastards live under the leaves so take time to spray well... secondly neem oil can be root fed to your plants as well.. during the entire time i have an infestation i feed neem to my plants... ill explain what neem oil does and why root feeding is good in the next paragraph.. but i feed each plant about 6 ml per gallon of water every other feed.. you can just incorporate the neem into your regular feeding schedule... only do this if its soil though... i wouldnt recommend it for hydro... here is how neem oil works.. neem oil is NOT a spot killer.. you wont spray your plants today and be gone of mite tomorrow... expect about a 2 week battle... neem oil works a couple ways.. first if you can spray the eggs well it covers them and suffocates them... no more eggs.. when the adults eat the neem oil it messes with their hormones... it makes it so they cant reproduce and lay eggs.. immature pests that eat the neem oil dont reach adult hood and are never able to reproduce... thats why spraying the plant well is so important.. you want to make sure the mites have no choice BUT to eat the neem oil... root feeding work very similar in that the pests hormones get ***** up when they suck the juices from your plant, but it also deters them from sucking on your plant because the neem oil tastes horrible... it also contains some trace minerals so its actually good to feed your plants,, i personally will root feed my plants every other time during and infestation, and spray them every 2-3 days.. the spray i use is 3ml neem oil per 1L of water with a few drops of biodegradable liquid dish soap... usually following this over a 2 week period.. then just go down to spraying once a week as a precaution... ill do this up to the 4th weeks of flowering.. havent ran into mold problems yet, or had neem flavored buds, or any other side affects due to the neem oil... its always worked for me.. like i said.. it just takes about a week before you see progress, 2 weeks before the infestation is gone... but its a natural way to get rid of them... if you want an immediate solution get some NO PEST STRIPS from walmart, lowes, home depot, ect.. they will work in a few hours and kill both mites and eggs... but it is a chemical strip (not a spray)... personally i dont want to think that what im inhaling was treated with a chemical... NO PEST strips work tho.. just make sure you arent in the area because they arent anything you want to breath in... also AVID and FLORAMITE are instant working sprays, but again they are chemical... chemical = instant, but it is a chemical you are using on your plant... natural = longer time fighting the pests, but its not chemical.. just depends on you... also.. a couple smaller ways of helping slow down their life cycle and battle them is; 1) keep humidity up... they hate humidity... spraying with cold water will help by raising the humidity, spraying them off the leaf surface, and they dont like cold.. which brings me to number two.. 2) drop the temps to between 65 and 70 if you can... it can take 10 days for mites to reach maturity in cooler humid temps, but as little at 2 days in warmer less humid places... each female can lay 100 eggs a day... they are 75% females anyways... in the right climate they can very very very quickly run your garden over... so until you decide how you are gonna deal with them and they are dealt with making the enviroment as unhospitible to them as you can will help slow their growth..." simpsonsampson420, May 13, 2009...See Morespartacus
