Hello all, These germinated about 12 days ago. I put them in a bubble bucket that I made myself. There is an airstone in the bottom. My tap water ppm is 100. I added some rapid start which only raised the nutes to 120. I have good well water. As you can see, spots have developed on the first set of leaves and are starting to appear on the second set. This is a strain called Jack Herrer. Sativa dominant. the other is a hybrid betwween northern lights and big bud. This plant is staying very short where as Jack H is towering over it. im thinking its because sativas are naturally taller plants. Anyway, If anyone out there is good at diagnosing plant problems, i would appreciate some advice. i had them under an LED and a 150w hps. I have since removed the hps and am using just the LED for now. I thought maybe the hps was too strong causing the spots. I had it about 2 feet above the plants. I wish someone would give me a step by step fool proof method from germination to veg because I always seem to have a hard time with seedlings. Anyway. Thanks and best regards.
Funny you mentioned that. I was thinking that might be the problem. I'm nutrient shy from my last grow cuz I stunted them by giving nutes too soon. I dont think it can be nute burn right? Thanks for the advice man!
I think it is a cal/mag def,but a 12 day old plant shouldnt normally have any defs under cfl,hps etc. Led`s somehow make plants use more cal/mag,so these nutes need supplementing throughout the grow. Good luck.
