These plants are 4 weeks and 3 days into 12/12. You can read more about the grow at: http://forum.grasscity.com/grow-journals/132093-original-haze-grow-2-pics.html The leafs in the "middle" of the plant are yellowing between veins. The veins of the leaf are normal green. The fan-leafs are also a bit pointy on the edges, pointing upward. This is shown on Picture #2 This picture kind of shows it, but it's been coloradjusted from a picture taken with lights on and therefore very yellow. The result may look a little different from what it looks like. It tends to happen on the plants directly underneath 3x600W. Approx 50 cm from top, with glass between. The room has approx 77 Fah = 28 Celsius when lights on, and 64 Fah = 20 Celsius when lights off. Bottom leafs are droppy (can bee seen on link on top of page), but they don't receive a lot of light either, because of canopy (Picture #3). Feeded approx 1/3 gallon water = 1.5 liters every 2-3 days (with nutes). In 18 liter = 3.5 gallon spoil pots. Pointy fan-leafs: Droppy leafs: Since plants are still 3 weeks from harvest now, and starting to get more and more yellow before the pure water period (drain) is about to start in 1 week, the question is if this is normal?? Anyone?
Mate one thing thats worth doing is flushing and dumping once a week in flowering ... it makes a massive difference ... you get a shower nossel gun for you garden hose and completly flush out every pot thouroughly ... let all the shit run down your lines into the resevoir and dump the lot ... start again with fresh nutrients .... this prevents toxic salt build up and makes sure you have the correct ratios of all your nutrients.... Nutrient pens only measure the total dissolved salts not individual nutrients ... so by regularly flushing and dumping you make sure everything is sweet ~
