Hi there. You may be running a tad to high on the Ec for an auto. I find if I push above a Ec of 1.4 I get problems.

This is nutrient burning, not a pH issue. Autos don't seem to like too much feeding in my experience. True nutrient lock out does not occur unless the soil is above 7.5 or below 5.5. Hope this helps, Organoman.

Clawing/Yellowing? (def not over watering)Anyone want to take a guess at what's going on with the clawing/yellowing? Very highly doubt it's over watering. It's slowly been showing more signs of it the less I water and I'm pretty heavy on perlite. Also using the lower recommended amount on the nutes.

Spots on leaves after giving water without nutrients I fed my plants last week. I have an intake fan blowing cold, humid air from outside into my tent and my plants are only drinking once a week. I gave pure water yesterday Ph'd to 6.3 which is same as 3 past feedings. I didn't give enough water for runoff. What do I do now?

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Leaves Curling Up I've seen some weird leaves on the Moby D... they look curled up and most of them have only 3 leaves. Can it be related to the LST ? Should I be worried ? Thanks for the support !!!

Leaves curling up My Moby D is showing some strange leaves (kind of curling upwards). Is this normal ? Should I be worried ? Also most leaves seem to have only 3 leaves. Maybe I’m too hard on the LST for this one ? Thanks in advance for the support guys !

Nutrient burn or light damage?Burnt tips appeared around week 3. I think the bio tabs are a bit too hot for this plant. The plant is growing at a good rate so I don't think a lockout is occurring. Burnt tips across most of top of plant. Could this be light damage? How to proceed or do I even need to worry?

Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.
