Leaves turned dull bronze and dropping, noticeable webs appear.
The most likely culprits are red spider mites. They are most active between March - October and love dry environments. Take the infected plant out immediately. Make sure to check all your other plants for cross contamination. Remove the plant from the pot and wash out the soil until the roots clean. Clean your pot thoroughly. Repot the plant in fresh soil and keep quarantined until the plant is re-established and new growth appears. Ensure the soil is kept moist to avoid new infestation. Return the plant to its original place once you are confident the problem has been conquered.
Deformed, dull green leaves with silver discolouration on the leaves and small brown spots.
This is caused by tiny insects called thrips. They can be hard to spot, so to confirm for sure, separate the plant, taking care there is minimal contact with neighbouring plants, grab a piece of white paper and shake the foliage on to it, which should reveal the insect.
Once confirmed, wash the foliage of the plant thoroughly under a tap, washing away as many insects as you can manage. For the second stage mix Neem Oil with lukewarm water and apply to the plant, wipe the leaves after 8-10 minutes. Ensure you do so in the evening when the plant is not exposed to the sun, as this may burn the leaves.
Do not feed the plant with fresh meat or dairy.
