Hi! So, my plant started to get orange rust spots on the lower fan leaves, that is now spreading to the other leaves. Im pretty sure its a pH-problem. Ive watered it with tap water that ive left for a few days before watering. \nI will get pH-sticks in like 2 days, before that I cant water my plants because the water has the wrong (too high I think) pH. Will it be too late if I wait 2 days? I attached a photo of the plant. Its just getting worse and worse with the rust spots, and it has spread to the small, new leaves. \nHeres the picture: https://anonfiles.com/file/036e93be03a2df2bf34c6862321ba61c \nYou cant see it on the pic, but its a rust spot on the new small leaves in the middle aswell. The spots are more orange IRL. \nIts an autoflower, about 2-3 weeks old. Grown in soil with CFLs. \nWhat should I do when I get the pH-sticks? Flush soil and water with the right pH-water? Please help, I dont want her to die. \nThanks in advance! \n(Sorry for bad english.)
have you been giving them fertiliser? It looks like nute burn to me if so put them in a clean tub and flush with water till the runoff looks mostly clean
Its getting worse quickly!! The photo in the thread start is about 5-6 hours old, and now its already worse. One new leaf got a lot of rust spots, just in those hours.. Please help, what can I do? I cant check pH level. Pic: https://cdn.anonfiles.com/1403182757147.png The leaf in the blue ring has rust spots now, a lot of them, which it did not have earlier today. The leafs that already had rust spots looks worse now. GAAAH, what to do?!
With reference to you pic. "Almost dead" is normal of an indication of a plant that has advanced nute burn indications on top left are typical of early to 'normal' nute burn right center is typical leaf phyllotaxy(its ok, plant will grow out of it) right-right is normal nute burn Understand that "RUST" is a very serious horticultural disease, and very difficult to get rid off once you got it, and with the amount of fussiness that cannabis gets it would be rare but not impossible to get. Treat you plant for nute burn cut back your feed until you see a positive improvement but first a flush, to my blog: http://forum.grasscity.com/blog/1093/entry-9829-flush-baby-flush/
