I've read these and yes they are very good but I'm still not sure what my problem is. The leaves start getting yellow spots then curl up and die. They are in Fox Farm sView attachment 1790000oil and are in the 4th week of flowering. They have nice juicy buds and are getting very sticky. Any ideas of what my problem is? Pics attached. I am feeding with Botanicare Pro Bloom 1-4-5 20cc per gallon.View attachment 1789999

i think this is awsome yet simple guide, very convienet. thanx very helpful. i was just wondering 1 thing= how can u always differentiate btwn nute deficiancy and lighting? like if the light is to far (for cfl's in my case) the stem can get spindly, or w/ no fan ...no? or like in my case 1 had fertilizer burn...1 had been burned b/c of bulb. the color i can tell the difference 4 that. but sometimes i wonder how much is light w/ cfl's and nutes. btw i gave my plants nutes when they were to young but they recovered. so i understood the yellowing part. but curling , cn that happen b/c of light/heat?

thanx in advance....best wishes & happy growing

Hi all! Any ideas what could cause this? These leaves are not on the very top so I don't think it's because of the heat from the light. I have a 250w CFL(red) about 6 inches away from the top of the plant and the temperature is about 26-28 ℃. It has been fed about 9 days ago when watered with Biobizz bio grow half amount of what the bottle says. I would start feeding with some bio bloom but I'm not sure what causes these brown dots on the leaves so I don't want to overfeed the plant if that was the reason. Any ideas guys? I really appreciate your opinions! Thank you!

My lowryders keep dying! I'm thinking it is too cold, it gets to
50 by the window at times, -27 outside this week. My other plants
are dealing with it but they were outside. Of three seeds, one
did not come up, two came up and died in a day, one was all moldy under
some plastic wrap over pot. Pretty pricey
seeds. Opinions? J
(just started a seed in a pot, inside a old crock pot that keeps soil at 90 degrees. will see.)
