Its not FFOF it is just some random potting mix. I don't think its heat stress, although my box is a little hot. Only thing is only one of the plants is showing the signs, the other is not.is this fox farm ocean forest soil? maybe your pH is low i hear ffof has a low ph. also make sure it's not heat stress
I'll give them some nutes tomorrow, but what is odd is that N deficiency should only cause yellow. Not the brown spots.you might have just watered that one more then the other - this flushes all the nutes out of the soil if there was any to begin with.
that one also looks a little stronger (larger) which would require more food - if you do the above it should correct your problem.
Supposedly they are from the same bag (GDP), but i don't really believe it. They could just be different phenos of GDP. One looks more indica dominant. Is it N or K that is missing? Either weay they'll get it from FF Grow big.View attachment 2435347Are they the same strain?
They look the same, but if they're not, it's possible one wants more K than the other.
I had one last grow like that, but one was Sativa dominant, the other was Indica dom.
Keep an eye on your root growth also though, around 15 days was when mine started showing signs of crowding.
