Nute lock or nute deficiancy?had some yellow leaves start to pop up on one of the girls. Looks like a nute lock that we will address with a PH water flush and then slowly wrk them back up onto the feeding schedule. Didn't check my Ph and my guess is Ph went too high in the soil.. Thoughts from my gurus?😇

Yellow spots Did these yellow spots appear on the plant, only on this one, could it be because of dry soil? Or lack of NPK?

New growth gets lighter in color Looking at the pictures you can see new growth on both plants is getting lighter in color each day. I’m thinking nitrogen, maybe? Complete day by day photos are in the diary. Thanks

To my outdoor growing gurus.. How do I schedule a regular nute feed????doing an outdoor grow and dealing with a consistent rain schedule every couple of days. Can i supplement a feed and give more water (think that's a bad idea), or do I wait until the girls are thirsty again to give nutes? Possible too much rain stunting growth?

Deficiency?Could anybody help point me in the right direction please? Are these plants showing any deficiency? If yes, what is it? Noticed that some leaf blade edges look lighter and the older leaves are showing some yellowing between the leaf veins. Thanks in advance!

Epsom salt as fertilizer. Whats your take on this folks?Epsom salt will not release hydrogen ions in water so my guess is that it will thus not affect PH. Making it a nice controllable source of Mg that would be not negligible right? How effective would that be to treat Mg deficiencies? Anyone has experience with this?
