as for kat, that does look like the begining of nute burn, can we get more specifics on the grow? what nutes are u feeding with at what strength? how old is the plant? it looks to be about 3 - 4 weeks old. if it was me i would be feeding it on a veg schedule with about 35% nute strength, and probably flower her in a week or 2. it doesnt look that serious and ur plants are looking nice so dont worry too much. just a little more info and im sure u'll get the feedback u need.
Feeding it GH 3 series, just doing the 1-1-1 ratio. Fed her 1/8 nutes about 1-2 weeks ago, then added another 1/8 or so a few days ago. The water hasn't been changed x_X. Should get some soon though fosho'! I'm unsure of its age, but less than 3 weeks ago as a "clone". She had zero roots and when I first lifted her, water gushed out like a waterfall...
Thanks for the response and compliments. I'll be sure to relay them back to her.
Hey whats up dude, my plant is kinda like yours almost same height, just a couple inches taller, but I noticed some of the tips are starting to turn brown, not really quite sure what it is either.
