ok ive been growing for a while and have asked some specific questions already and just came up with 2 more. they are pretty much cross board so if you dont know the answer to one of em pls answer those you can. any help is appreciated! 1. I read that leaves which curl over, especially at the ends and are brown are a result from over-fertilising them. My leaves curl down slightly at the front but are not brown and i doubt i have overfertilised seeing as i only planted a few of these sticks like 2 weeks ago with nitrogen in them. could this just be a natural reaction to the weight of them growing too fast? 2. Is it obvious when I have an insect problem, like a big one or does it creep up on you really sneekily? cos i read that the worst case are small white pathces on your leaves as a result of a particularily nasty insect. I then proceeded to panic and checked all my leaves to find i couldnt tell the difference between the small little pollen dust that falls on them sometimes and what could be an insect attack.
