What's wrong with my ladies?

[Mikegetshigh]

I'm currently growing 3 different strains of clones (organic). One of the strains' leafs began turning brown 3 weeks ago. I thought it'd be over nutrition so I watered with water only for two weeks but the problem still exist. Im using roots organic and I've fed them aerated tea (bat guano, vermicompost, blood meal, molasses) in the past but I'm not sure if this is due to overfeeding. Can someone tell me what's wrong with my ladies and what I need to do. Pix are included. Thanks in advance.

Have you given any magnesium (epsom salts)? They generally need a dose at 21 days flower. Might also be calcium deficiency. If you haven't got some CalMag at hand, it might be worth getting some.

If it's not that then i'd re-check the water ph to make sure it's in the right range (5.5-6.2 for soil).

Like b8man said, check PH, might need some CalMag, don't over water.

Good Luck

A really good way to recover any nute burnt plant ...is to leave the leaves on....!
..and yeah . No nutes until you see a recovery..?
