Hi everyone, another newbie question here. I’ve checked previous threads and it’s looking like mag deficiency but I’d really like an expert’s opinion. I’ve come too far to mess things up now! The strain is blueberry kush, from feminized seed. Planted in a homemade soil mixture using LED lights. I’ve only been feeding fox farms tiger bloom mixed in dechlorinated tap water for the last several weeks. The ends of the leaves are curling slightly and a few of the leaves are “bleaching “. I’d appreciate any advice on remedies or if it’s a normal aging process, thanks!6C378C2E-81A6-44BC-A93F-BA3E4CC4A2A6.jpeg96A07372-A27A-4016-9715-6B9A1DBB78B3.jpegDFBA319F-4981-40F2-BA63-8BADB9A7E548.jpeg

Bloom boosters like tiger bloom can acidify the rootzone, especially if too much is used. I would check your pH of your soil, if its low you will want to shoot for a higher input pH. It looks like Calcium deficiency (rusty speckled leaves) or lockout and possibly some Magnesium deficiency.

Tiger Bloom has a lot of Ammonium compounds in it which can cause an acidic situation when they're in excess. I would discontinue the bloom booster at this point and just water your soil normally.

They look great otherwise, I'd start by making sure your rootzone isn't acidic. The most accurate way would be to use a glass soil probe but other methods are slurry tests and or testing runoff (least accurate in my opinion, can really have you chasing your tail). If the pH is high then feed an input solution that is at least 1.0 pH higher than your target rootzone EC. e.g if the pH is 4.5 and your target is 6.0 you would want to feed a 7.0 pH water solution until things balance out.

Did you add any Dolomite Lime or Oyster Shell to your homemade soil mix? If so which ratios?

Thanks Calvin, I appreciate your advice! I added lime when I mixed my soil. I have a soil ph tester and will test it out in a few minutes. I will definitely discontinue feeding and go with just water. I am quite proud of her and would hate to mess up at this stage of the game. Thanks again!

Ok, just checked the soil and it’s at 7.5 ph so I definitely need to adjust that

Yessir so its actually opposite of what I was thinking. I usually go 1.0 pH value lower or higher than what my target is. So if you are at 7.5 and want to be at 6.5 in soil I'd give them a one time feeding with something like 5.5 pH solution to even it out to your goal pH.
