heya guys, had a plant under 600w 12/12 under a brand new dual spectrum bulb and was called away for a week, the plant got pretty damaged and dried out. About 5 stems are nice and green, the rest (it was lst'd) are a light brown, think they're wasted. Is there anything i can do to revive it, ie misting it every hour? Would it be better to cut off the dead leaves?
ps is there any visible difference between too much / too little water and heat damage?
Heat damage is evident by crispy, crumbly leaves that are close to the light. Typically it is localized, in only the spots that are close to the light.
Over/under watering generally shows up as wilted/dried leaves, with an overall droopy look. Check the stickies in this 'sick plants' board for more info.
I wouldn't bother misting her too often, you'll just create too much humidity and hurt her more. Don't bother cutting off the leaves...just pick them off when they're ready.
What exactly happened? While you were gone, did the plant grow up too close to the light? Was she underwatered?
I suggest just giving her some TLC...maybe some nutrients if she's due for some, move the light farther away, etc. If there are parts of the plant that are definitely dead (gray/light brown stems) they probaly won't recover, but if she turns around she'll sprout new growth after a while. It's just like re-vegging.
You mentioned that there is water sitting at the bottom of her tray...do you mean she is basically sitting in a puddle of water? This isn't really good, it can cause the soil to stay too damp and the roots to rot. From what I've noticed it's best to leave everything around/under the pot dry, just have the soil hold the water for her.
