Top of my 40 day old Blackberry Auto has gone light green. I am using 1000w of HID lighting and this is the tallest plant so I suspect light proximity, but I'd love second opinions.
Hey buddy. That immobile nute def. Micro nute def. You need to add a micro nute that has all the lil trace elements autos need because of their ruderrails. The micro I've found that's the best and has the widest range of micro nutes is jungle juice micro, or just get a GEH micro from Amazon. Good luck pal.
@SeedsNStems,
Here's hoping :) It's certainly not the biggest plant, but I was mostly looking for purple and i got that in spades so I don't care in the slightest.
@SeedsNStems,
If you check out my other journals, the FastBuds Purple Lemonade is what I'd so far recommend if you are just looking for purple colours. My tent is 26-27 C and its still bright purple at week 6!
