Hi Everybody My plant looks healthy but there are small red spots on the top and spots on the back on a few leafs on the top of the Main cola, it’s in the 4th week of flowering. Can you please help me to find what it is and how to treat it? Thanks

Hello So i think the spots on the front are getting big and deep enough that they're showing through the back now too. To me it looks like the rusty spots from calcium deficiency. Often a calcium is accompanied by a phosphorus deficiency, but is sometimes down to the ph being far from 6.2 which is where calcium is best absorbed. However me personally, I noticed a big difference in my plants once I started using a calmag supplement regularly (at least once a week), i figured my water had enough but the leaves were much healthier after getting a more steady diet. So possibly look into the ph, adjusting your amount of Ca, and then if any other nutes are too high they're locking out.👍

Most I can say, ifmyour feeding by what the fert label say you have lockout, you need to flush the nutes out and refeed at half them dose your flower nute label says and watch new growth, the damage will get worse now on those affected leaves so dont watch them to get better. Cheers

Dont know how much your feeding,what your growing in, if you feed all the time without a break, we know it's a deficiency but is it from lack of or to much feed. Lockout or starving? INFO really helps us help you friend. Cheers
