Yellowing and browning HELP please
    #661416 - 03/07/13 10:15 PM (3 years, 8 months ago)



Hi, this problem has been happening for about 3 weeks. Now is day 40 of flowering. the lower branches of the plant with buds are now turning yellow and brown as that fan leaf.

I've guessed it was nutrient burn for a while and kept flushing with the limitations I have. Now I've come to think it may be a combined deficiency in nitrogen, phosphorous, and calcium.

Anyone would could help this fart out?

Thanks in advance, FromTheWest!

Yeah looks like a number of deficiencies.

Flush and give it a 1/4 dose of nutes

Alrighty, though I only have some nutrients that is miracle grow with a high nitrogen concentrations. So I heard that it doesn't allow the plants during flowering reach full maturity with it. Also, I have only been feeding it molasses.
