i agree, the signs usually appear during bud because no one adds nitrogen cause it makes your buds burn like shit... give it age old kelp because its a really small dose

I havent been feeding it too much, so i think it could be a defiency, but other wise the plant is nice and green, but some of the foliage is starting to lighten up to a light green.

I plan on feeding her in a couple of days with 1-9-9, with also molasses, liquid kelp, castings(the 1 % N) and some dolimite lime.

Would i be correct in this feeding to correct the purple leaves and the newly light green leaves?

Thanks, swisha

PS. I supercropped it about a 3 days ago so the middle of the plant that is lighter green is ultimately the lower growth, its white widow

Swishatwista.... The color purple can show up when nightime (or lights off) temps drop in the upper 50's. As a plant finishes, it draws all the soluble NPK from it's older fan leaves. A completely natural cycle. This causes chlorophyll to breakdown (loss of green color). This can show up as yellow or with some strains, purple, maroon, blue and even black.
.
Your plant looks fairly healthy, a small bump of Nitrogen will probably dail this back in. I shoot for a N level of 2 to 3 during the last half of flowering, then no ferts the last two weeks, to ensure smooth smoking buds. If you have been using the 1-9-9 mostly, you are too light in the N dept.
.
Vita Grow makes a great dry fert 17-0-0, made from calcium nitrate. Most online hydro stores carry it, if I recall correctly, it's labeled as Part B of their three part dry ferts. A pound of it, runs like, $ 5 I used to use this when I did chem / hydro growing. It's cheap & effective.
.
Half a teaspoon of it and one teaspoon of epsom salt to (2) gallons of water, makes a nice N only fert (with cal & mag in proper proportions), great for dailing flowering plants back in. Mag-i-cal (Technifloria) and Cal-Mag (Bontainicare) are basically this same mix. Just premixed and more expensive.
.
Use this mix on your watering day, then wait two days before resuming your normal feeding schedule.

Hope this helps.....

Damn, yea i fed her the tea with an NPK of about 4-10-9, but the purpling increased pretty rapidly on the leaves it was already on, as well as a few other large fan leaves. The plant is also increased in its amount of light green leaves, could i have over fed, which im thinking what it is, or something lockin out the N.

Any advice would be great, thanks guys
