after relizing i couldnt buy any superthrive cuz its on recall i went back to wallworld, (Did ya know,Now you can buy worm castings in a spray form at walmart) just spray it on your leaves,soil once a week..
idk..I just seen it.thought id ask,since it was on the topic here,and ya looks like a slight nute burn.nothing to be too worried about.just add some more water to whatever your useing for nutes...dulute it down a bit.
as long as they dont turn brown and fall off your good..and i highly doubt they will from your pics..
I was going to ask the same about your last pic and its top..looks like you topped it??
but them pointy leaves look like they are cuz of the strain,do you know what they are,or they bagseed?
i would quess a sativa strain of some sorts..
if they are bagseeds..what was the weed like..did you fall asleep on the couch or can u still kick it and not be dragged down? thats a good way to tell the diff between sativa and indica strains...indicas-are couch lockers..and have fatter leaves.
and just curious..that looks like a small grow space,with hps..hope you got some vents in the top of that closet or a ac unit in that room the closets in...
