Hello everyone. Ive been reading this forum for a while now and decided to join up in hopes of learning to successfully grow my weed. This is my first grow and I have a problem with one of my plants that I cant find an answer for. I'll try to include as much info as I can but I'll probably forget something!
This is a White Widow Auto that is 8 weeks old.
*This one is planted in a 5 gallon smart pot with FF Ocean Forest with ~25% perlite added.
*Nutrients started off with the Technaflora recipe box but my last feeding was with Masterblend/Epsom Salt/Calcium Nitrate at 2.4g/1.2g/2.4g per gallon.
*Im only feeding once per week with ph'd water as needed in between. PH adjusted to ~6.4.
*I switched to the MasterBlend this last time to see if a different nute would help the problem but so far it hasn't.
*The problem is the brown/rust colored patches on the leaves. I've looked at photos from numerous websites until Im going nuts trying to decide what the problem is. I thought phosphorus deficiency was the closest match but some pics kinda favor magnesium deficiency. I don't think it's rust because the patches are not brown/rust on the bottom of the leaves.
*I did a flush with ph'd water last weekend. The runoff was as high at 1300ppm but I was able to get it down to around 400ppm after running about 20 gallons of water through it. My well water is 155ppm out of the faucet so that should work out to 245ppm runoff.
Here are some pics that hopefully someone can identify what the problem is. I don't want to lose the plant so close to being finished.
Thanks in advance for the help!
