mrhat2001 started grow question 3 years ago
Guys been going great until I checked today. My top leaves turning grey white and crunchy on 2 plants. 3rd plant ok. What do you think too much Kool Bloom? To much heat from the light?? I don’t think it’s the latter I decided to flush for 2 days to clean it out??

Hey man I know im late to the party but that your lights doing that for sure , its burning up the chlorophil in the leag and its drying out and then you can basically crumble it . All the classic signs are there man even the leaves being bent upward into the shape of a taco . Thats how it will start out small bending upwards until its very exaggerated and then they will dry out turn brown/white and crumble up like a dead leaf would if you found it outside . I advise that you raise your lamp to 20 inches from your canopy this will greatly reduce the heat on your plants . If raising your light isnt an option you need to get more ventilation in there to cool the light down and reduce the over all temp of the room . When you start to see damages like that you can also be assured that some of the THC content on the top parts of those buds will be burnt and less potent then some other parts of that plant . Over all its an easy fix you just need to raise your light or get some more ventilation in there and you will be back to rocking and rolling in no time. I would also advise you trim away all those dead leaves in order to prevent any unwanted pests from making themselves a nice home this will also encourage and increase air flow around your plant . I hope this information helps you understand what happened to your plant here , the signs that lead up to it and the ways you can fix it :) - Happy Growing!
