Hi Guys,
My plant looks pretty healthy. However about 2% of the leaves are going soft, then they loose their green color - going browny- skin colored. Then they drying up and dying. This is all starting from the tips of the leaves.
week 3 of 12/12. EC 1.0 PH 5.8. Temps 70-85F. Bubble Bucket. 1,000W HPS.

Seldom does Bird make any sense, they're just guessing that "something organic" is your problem. If bird knew, they wouldn't be so vague. They don't know.
Personally, I see your temp is a little too warm and your feeding too much fert, so it looks like a combo of the two. Try to get the temp down if you can and cool it on the excess ferts. This is what I said in post number 2.
