Hello, I have been seeing a friends crop because i take care of it, he has very bad cancer tumor and cannot walk or move very decently without being hurt. I have purchased Serenade Disease Control, House (R) Insect Repellant. Also a OMNI Spray bottle of a of mix Coco agent and Einstein Oil. He bought them as clones, healthy as ever, no signs of pests or disease. about 2-3 weeks into growing, there were some signs of displeasure. Leaves begin to rot, curl up, and show a weird color. So i am not a biologist, yet, so I do not know all these diseases even though I can research them. Too time consuming. So please anyone help me so i can do something about this problem. Pictures included All grown in a greenhouse. I believe they are 4-5 weeks old, 1 strain - NO signs of disease or pest control. Sativa, 10 inches. tall. 1 strain, Indica, Triple P OG - Some signs, not much. 8 inches. 1 strain ? Maui Wowie - Very bad results 10% leaves are in horrible state. 7 Inches tall
it doesnt look like a pest or desease problem. im guessing it is a ph problem. first check your ph and make sure it is in the correct range for your medium. you should post what soil or medium you are using. any fertilizers you are using and at what strength compared to manufactures full strength. how often you fertilize and water. as well as pictures of the plants and a description of where the damaged leafs come from. all of these details will help make acurate diagnosis. it is imposible to tell just from a few leafs layed out on a table. the more info the better. if you look in the sick plant section there is a sticky thread with a format form for posting. fill it out and post it back here. with asmuch information as possible the more the better. i want to help you friend get some high quality medicine. i am unable to make a educated diagnosis with the infromation you are posting. i would hate to say you are over ferting when it is the opposite.
I'm using Roots Organic. for nutes, im using bionoicare vegative, bat guano. for pesticides, House insect repellant, Serenade Disease control, cocowet and einstein oild.
