red tips!!! 2-3 weeks from Harvest!

[jimmyrauch]

soil, 12/12, 400wt hps, canadian xpress - coco bloom and super thrive.

they have gradually gone red over the last 2 weeks. other than the color they look healthy.
they are a native outdoor strain, so i doubt it is a nice purple indicia coloring.

sorry about the pic quality.

i dont think its a problem
normally the leaves die off kind of eats it self at the end of flowering

Phosphorus. deficiency, slow and sometimes stunted growth. The leaves develop red or purple color starting on the veins of the underside of the leaf. Generally the tips of most of the leaf blades on the lower portion of the plant die before the leaves lose color. Lower leaves slowly turn yellow before they die.i would Remedy with any P-containing fertilizer ,but as your only 2-3 weeks before harvest then i would give a 1 off feed of phosphorus containing ferts at 1/2 strength........then it,ll be flushing time over the last 2 weeks(dont worry if no improvement, but it wont do any harm giving it a feed of "P")

Affected leaves do not show much recovery(especially so late in flowering), but the plant should perk up, and the symptoms DO NOT progress.

As its a bit late for your baby to really see any difference, but keep this as reference for future grows, handy info

Really would'nt worry mate as your grows nearly done.
