Not sure if this is a bug? Lts of stuff blowing around my tent and dog hair and god knows as its an open tent.

Had exact same problem last grow. Linked here: https://www.autoflower.org/threads/orange-brown-spots-on-leaves-day-23.75297/post-2224629

I think its micro nutrients and prob magnesium cos ive seen CA problems in my other plants.

Any ideas? @Waira Last time you thought it could be Ca or micronutrients cos of the RO water....given the nutrients and super soil composition i would have hoped we were good.


-Medium/grow method: super soil. transplanted from a 50% peat, 25% perlite, 25% vermicompost at day 14. Problems existed before transplant.

-Feed and supplements used: Neem cake and Organic Veg dry amendments (clamshell powder, bonemeal, alfafa, seaweed, compost, worm casting). Seaweed foliar everyday. White clover planted at transplant.

-Water source: Reverse Osmosis bottles. PH of water about 6.5.

-Strain and age - Biscotti Mintz (17 days from sprout)

-Climate: 60-70% RH and temps always 22-27c


- Light used: Mars FC8000. 40cm distance and 25-35% dimmer

Can't really tell what that is but it is to early to have nute deficiencey.Don't over feed and use a little calcium and keep ph corrrect.

Thanks, appreciate your time. Im leaning towards Ca and micronutrients. Could be an entire PH problem too. Yikes.
 
Your last picture with the spot of leaf discoloration is just that. I have an entire leaf that’s half like that and half normal. Kinda like two face from Batman. I wouldn’t stress that to much. My plant is going strong even with that and so is yours
