Cannabis Troubleshooting

Has anyone had root aphids? I'm not positive if they are root aphids or fungus gnats, but I need to figure it out fast cause their multiplying faster than rabbits. Anyone had experience with either?

This is a new problem to me I have a few seasons under my belt and consistently yield excellent results. I scored four clones so I put them in a fully decked out grow tent (400W hps air cooled, 150 Cen Fan, 150x600 Carbon Filter, 4 x 15 ltr dbl pots in a Recirc Sat system) The tent is well controlled and stays between 25- 28 degrees with 45- 60 % humidity. The nute tank is 50 ltr and has pump, heater and air stones, water temp set at 22 degrees. I use rain water and set to an EC of 1.2 approx and PPM 0f 800. Dutch Master Advance Nutes with silca an zone added. Medium I use is perlite with a feed schedule of 15 on 3 hours off... All this to me seems fine but the cl…

Hi! On Wednesday, I noticed the leaves at the bottom of all 3 of my plants had turned yellow. Today (sunday), I had another look, and the leaves above have started going yellow on the edges as well. On the leaves on the very top, little specks of yellow are appearing all over as well. I was thinking a magnesium deficiency but I'm not sure. (Sorry about the picture quality) Also, on the other plants, a couple of the bottom leaves have curled up and died?

Hey all. My poor little bubblegum sprouts have been through a lot this week. I had them set up to be fed every other half hour, and as such they showed signs of over-watering. I stopped watering them for almost the entire day, and now have them set to be fed 4 times a day, for a half hour each time (half-hour units are the smallest I have to work with). Now the poor little guys are getting more burnt looking spots on the tips of their upper leaves, and show limited signs of recovery from the over-watering. Now I'm going to be gone this coming weekend (plus Monday), and I don't have anyone to entrust with their care, so I'm stuck with the timers. I'll post pictures, but th…

Hi all... the plant I wish to make a mum out of appears to be ill. Her leaves are very yellow and thin (see pic). She currently resides in a DWC 10L bucket with netpot. On weak veg nutes (canna), bioacids, root conditioner and superthrive. Her roots are not like the other ladies either. She's very "stringy" - with lots of short roots coming off main roots and a light brown colour, whereas the other ladies have nice vermicilli-like roots which are creamy-white. I have checked the pH and it's ok. Is it likely to be a Magnesium deficiency, and if so, how do I go about fixing her? I know it involves epsom salts... but how much, and should I flush her first? Any help would…

hi guys and girls, I have discovered some small white/yellow insects that seem to me like thrips. They are all around my clone tray and underneath the heat mat but as far as the ye can tell - not yet on the clones. They are crawling and 'hopping' like fleas which suggests to me that they are prepupae moving into adults? The clones are in RW and have only just shown roots and are still delicate so I am unsure whether to dose them with my trusty Pyrethrum? Any suggestions? I was taking a pic but batteries dead - maybe in a few hours... Jimbo

Hey all. I've got half-month old Bubblegum sprouts that have been growing beautifully in rockwool, and just today I noticed what looked quite a bit like burn marks on the tips of the leaves. Did I have the light too close? It's just a 60 watt fluorescent thats been hanging maybe 3-4 inches (8-10cm) over the tops of them. Moved it to about 6 inches (15cm) away today. Could I have misdiagnosed the issue?
