Leaves turing brown on tips and transparent

Post by Benben11benben »

I'm growing in a closet of about 2 x 2 foot by 6.5 foot in height. I have a zkittlez auto fem plant growing in coco with perlite and such its 2 weeks old. I only use small amounts of cal mag and ionics range of grow boost and bloom nutrients. I have standard 4 inch intake and intake fans as well as a small desk fan. I have recently changed from a 45w led to a mars hydro 300w true watt about 140w and have recently been seing brown on the tips of my leaves and today saw the leaves curling down while the edges are still in prey position. I doubt bite burn as I use less than half the reccomended dose and the light is about 35inch away from the plant which is higher than the reccomended so I'm not sure if it's light burn? Any help apreciated i have it on 20/4 light and have pics but can't figure out how to upload lol. Tia

It's almost like the change in light has stunned and burned it but i don't think the mars would have that sort of power from that height. May just start again

Hey Benben,

Can you please let us know exactly what you have been feeding, the amounts of calmag and when. What PH are you feeding at?

Ionics great. Flush them with fresh water, restart feeding with an ec of 0.6 mate, ignore calmag till they grow a bit.
