Hey all. Found some, what look like eggs on the underside of one fan leaf? Removed the leaf and had a good look over the plant, no strange bugs hanging around. Any idea what they are, what they're from and should I be concerned? Thanks in advance.

This is something I haven't seen before, I am looking after a few plants for someone and the bloody mice seem to be burrowing in through the drainage holes and making tunnels through the coco. Just wondering if anyone has had this issue before... The coco is sans perlite and as yet, most of the plants haven't quite got their roots right down to the bottom of the pots yet. I cleaned up and refilled a couple of pots and set some traps. Today the trap has been covered in a pile of coco as the culprit chose the pot right next to the trap.

One of my plants is struggling due to what i believe is gnats. The plants leaves are wilted like they have been over watered but only on certain areas of the plant (plants outdoors and about 7ft high), other areas look completely healthy, there is also some yellow blotch like stains on some of the wilted leaves and the middle fan leaves are yellowing and dying. I know a picture would help but i dont think that is possible unfortunately. Ive laid out a few yellow sheet sticky traps and have caught what look like gnats to me so ive been to every bunnings around my area and none have eco-neem in stock, it seems everyone is after it lately. So i figured i would order some gna…

Hey folks, my plants are going well... although i have noticed a little browning starting to take place at the roots, aswell as some kind of green (possibly fungus) forming on the rockwool. My plants are always in cooler conditions, have good airflow as i put them outside in the sun throughout the day, and under the lights at night time. PH is 5.5 im using seasol, canna coco A & B at the moment, 2 x 10ml hand feeds per day i think i chose to large a size of rockwool and i would have less chance of root rot etc if the rockwool wasnt in the picture. Is it to late to remove the rockwool? how delicate are the roots at his stage of growth? and would it be possible to g…
