4 and half weeks into flower now and the fan leaves are getting dark little spots on them and they are shading on the edges brownish/red, also the leaves popping out of the buds are starting to shade brown/red but no spots....what is happening? here is a pick
Here are some more pics.... one on the left is 4 weeks in, and the rest are 4 1/2 weeks into flower.....should I stop using the big grow and do a cycle of tiger bloom? the big grow is mostly worm castings and bat guano...
You definitely have some problems, what happened to your fan leaves? Looks like nute lockout and PH spotting to me. Check the soil PH and also put some PH 7 water through the plant and capture some of the runoff out the bottom, check the PH of that runoff.
Get back to us on the PH plz.
Could it have been heat? My 400watt HPS was like 10-12 inches from the plant, it was pretty warm, not hot but warm.... so I moved it up to like 17-20 inches maybe that will help, who knows....
Get a thermometer and actually check the heat at the top of canopy, right under the top leaves. you can manually check too, feel the top fan leaves between your fingers, they should feel cool to the touch, if they are warm they are too hot.
