With a 400w Mh you won't need a heater in their, why risk it? ...you have mild nute burn cut back you nutes by50% for the next month, then slowly increase nutes by 15% per feed, but right now your plants are due a flush ....to my blog: http://forum.grasscity.com/blog/1093/entry-9829-flush-baby-flush/
Thanks vostok for your comment. I will do a flush. But about lowering my nuts. I did 1/4 strength then 1/2 and only 1 time full strength. Also iguana guice is organic so it should be harder to get nut burms? Right? Sent from my SM-P601 using Grasscity Forum mobile app
