Looks like calcium deficiency starting on lower part of the leaves. .1ml seems low but I'm not sure the source that you are using. 1ml per litre of water should help correct this in 7-10 days.

Curled leaves and brown spots Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Leaves keep turning brown and yellow It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

Burned upper leaf edges Hi! Dark spots appeared on some upper leaves overnight. I don't think this is the cause, but I did a pretty heavy defoliation the day before. the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish. what could this be?

Strange Shape One of my two Super Lemon Haze Auto plants is growing just like this. I didn't use nutrients for the past week trying to see if it returns back to the normal shape. The other plant is growing fine, also watering with no nutrients in a soiless. Any ideias on what can be happening?

Weird leaves My little plant looks a bit sad, leaves are a bit deformed and have different color kind of spots, does someone know what the issue might be? I was thinking it’s from low temperature but I’m not sure. Thanks for any advice!

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.

Leaves always droopy?Is it normal for some strains to have droopy leaves? It seems like no matter the time of day or water schedule my leaves never quite perk up like they did on my last grow. The fan leaves on this particular plant are massive so maybe their weight won’t allow them to perk up??
