Possible Humidity Problem

[privatepile]

The plant is abot 5 weeks old now.

Im still using 20/4 light schedule.

The reason the plant is so small is Nute burn when it was young and incorrect light spectrum for 3 weeks.

The problem is that some of the leaves are drying up.So bad that they are crumbling away.The leaves are still green so its not nute burn.

I dont know what my humidity is but i reckon the air is too dry.

I was thinking of adding a wet face cloth behind the fan or else spraying the leaves with a mist of water.

Here are some pics

That plant is way too deep in the pot.
The soil does not appear to have any lighteners.
Re-pot into good soil and raise the level of the base of the plant up to no more than 1 inch below the rim of the pot for better air flow. That is a classic suffocation symptom.
BTW the leaves can still be green with fert burn, just the tips get scorchy.

The other plant is higher up in the pot and there is no problems with it.
