@Rookie808 What are you growing in? What are you feeding?
fox farm ocean mix, and i WAS feeding GH, but my plants always acted like they were gettin nute burn. I was using half strength too. the sun is just so bright in july that they just soak it up waaaay fast. first summer ive grown, 2nd of my life. ive been using filtered tap water, but not RO water. Ive only fed them 3 times, and theyve been outside now for 2 weeks. 2 plants grew huge. 2 plants stayed small, and one in the middle. all planted at the same time. weird.
so as an update, one plant (these are white widow x big buds and 1 northern lights) had curling, brown leaf tips... rust colored... on otherwise green leaves. dozens of leaves fell off, i cut a bunch off too with sterile, sharp scissors. so much new growth grew back that it almost looks perfectly healthy and green everywhere. at one point, i thought it was going to die.
another plant has no rusty curling tips, but many yellow leaves. i think i may have been underwatering... my skills at determining moisture in a 10 gallon fabric pot arent great. ive been watering more, getting more accurate, and its the biggest bush out there. i topped the hell outta my plants so theyre more spheres than trees.
i also learned that spinosad isnt enough. i got sick of my lack of success and went to the trouble of using neem oil. wish i wouldve done that from the jump. holy shit the few bugs on there went running for cover. id find one or two leaves theyd gather on an hour later and just remove the leaf altogether. Heres a video of what it looked like under a small microscope for the iphone... i see aphids, but cant recognize the others 100%. can anyone else?
ill take pictures of my plants tomorrow to see if anyone can help. maybe it IS a magnesium issue someone else mentioned? good god are there a lot of variables to growin herb... its intimidating the amount to learn...
