Please help.....its spreading daily

[luden9219]

she is in her 3rd week of flower. Im using Fox Farms potting mix and Fox Farms GB, BB, TB. I have over 200 watts of mainly 2700k cfls and a few 6500k.

First noticed this about a week ago and thoiught nothing of it. Now it has consumed 3 full fan leaves and 2 more are looking damn bad. Check the pic!

run off ph was at 4.8 2 days ago and after some flushing its stable at 6. Im scared to add nutes or not becuase I dont want to make the wrong move.....sometimes doing nothing is better????

From the sticky diagnosing plant problems....

pH Fluctuation

Both of these leaves in figure 3 and figure 4 are from the same plant. It could be over fertilization, but more likely it is due to the pH being off. Too high or too low a pH can lock up nutrients in the form of undisolvable salts and compounds, some of which are actually toxic to the plants. What then happens is the grower then tries to supplement the plants diet by adding more fertilizers, throwing off the pH even more and locking up even more nutrients. This type of problem is seen more often in soil mixes, where inconsistent mixing of the medium's components leads to "hot" spots.

This would be my immediate guess based on what you said about your pH. I would say not to fertilize (as does above) and just try to fix your pH. It could also be some kind of nutrient lockout, caused by the pH, but I can't really pin point which one. Good luck.

Thanks for the info. Now that Ive flushed and things seem a bit more stable should a feed her?

The brown spots and rusty colored leaf death is still spreading. The buds look great and are still growing new life but the fan leaves really are looking bad.

I dont want to loose this plant for be forced to harvest prematurely. I need some input!!!
