First run of autos and organic soil no nutes: orange rusty looking spots

[Cbeazy95]

So these plants are 6 week old autos. Grown in super soil. Solved early over water issue. And magnesium diff. About ten days ago some of them started getting really bad orange spots on lower leaves. Got really bad one plant. This plant started flower about a week ago. They look really puny still. I've tested my soil. Plenty of main three nutes. Soil ph 6.5. Help. Feeding every 3 days no nutes only to water and liquid seaweed.

Hiya Cbeazy95 I ain't no journeyman, but I've seen this, so while it kinda looks like possible bug sign in the first few to me but that last pic and what you described says you are running out the cal/mag issue still. Top growth looks good, that's what's going on right now. Old growth is showing what you did wrong two weeks ago. Might be working it's way out of lockout. Stay the course would be my suggestion, work your nutes back in real slow once you see some perk. And search for "castile soap bug spray", it's safe on veg and bud. Get it going as your best remembered habit now and forever. . Don't be a me. CHeers, gl mate!

That was gross, OMG sorry! Here's one of your problem...this plant had those leaves on it till it was 4 feet tall with 12 big colas, grew right past. I left them on as proud battle scars.

I don't see the signs of any bugs, but I do see a magnesium deficiency. The common calmag supplement is made for exactly this problem. Get some asap.

You Said your soil is 6.5. how you test it. What is the ph of your water? Coz it s look like a ph fluctuations to me.

 

[Emilya Green]

If he is running in supersoil, which doesnt care about pH, and he is not giving nutes that need to be pH adjusted so as to be mobile within the soil.... IT IS NOT PH. The soil pH is not even a factor and measuring it was a waste of time. This is nothing more than a magnesium deficiency.

depend if he's ajusting his water with some ph down or up. that could kill the benefic bacteria responsible for buffering ph in supersoil. if there is not enough of those bacteria, yes he needs to check the ph . or if the soil is at 8 , or 5 , its a bit too much for me even in supersoil . chlorine can kill tose bacteria as well , so be sure there is not in it. making a compost tea could help to get some of this bacteria that help buffering, it is never a bad idea to make one just to be sure . but yes normally you shouldnt check the ph in organics grow, if you do everything right.
