Leaf edge or tip browning is often caused by salt buildup in your soil. I would but the pot in a tub of water, emerging to the soil surface for an hour or so, then remove it and let it drain. From now on when you water, apply enough so that about 20% of the water applied, can be seen exiting the drain holes. I am assuming you are using a soil less potting mix, preferably bark based, and well drained. Al

Keeping the pot emerged in water for an hour won't damage the roots, will it?

No submerging for an hour will not cause a problem. The object is to flush out the potting soil of accumulated salts from previous fertilizer applications. Too often fertilizer dissolved in water is applied to dry soil and not flushed through the pot drains, thus an accumulation which causes leaf edges to burn. Al

Thanks a lot! Will try tomorrow. Also I just noticed my incorrect vocabulary in my last post so I apologize for that!
