Nice looking plants boys! I'm on day nine of my flower period, but man did I dodge a bullet.
I became concerned that I had not given my plant enough food and I gave it a small bit of nutrients during what would have been a regularly scheduled watering.
It wasn't long before some smaller under growth turned yellow and died, the edge tips of leaves began to curl up, the terminal tips of many of the leaves began to turn lime green, and other leaves became brittle and developed spotty brown regions. Likewise, claw leaves began to appear in the growth tips and there were no signs of any significant stretch. Clear signs of overfeeding it seemed. I flushed to what seemed a satisfactory level and hoped I had done enough to fix my mistake.
My biggest indicator was that it seemed as though everything was happening all at once, all of a sudden.
Growth seems to have resumed, stretch hasn't taken off (I wonder if it will, yet hope it does). I've noticed no more deterioration and the claws seem to have grown out as well.
Looking around RIU, I've noticed a lot of bad nutrient advice. Be it lockout or deficiency, there seems to be a considerable number of misinformed, inexperienced growers simply repeating things they've heard, but never seen. I would have liked to have taken pictures and documented the episode in order to contribute to the community, but the camera is MIA and the phone takes terrible pictures under that HPS.
Either way, here are a few pics of what things are looking like now that we're back on track.
