3rd Grow - First Auto Grow - Leaves Curling

they all look a little nitrogen hungry. Go back to photos man. Autos are a never ending headache. you can grow photos with the light 12/12 from seed and they end up about the same size as autos and only take a couple weeks longer.

 

I'd swing on over to Os's autoflower thread.That's were many of the autoflower experts hang out.

Did you top dress with worm castings and kelp at the first signs of flower? They look hungry to me. They also look thirsty, maybe dry spots in your soil mass. I'd top dress. And then slowly water 1 cup at a time every 5 minutes until you see a tiny bit of run off. Then resume normal watering in 3-4 days. Your soil may have went hydrophobic and slowly watering will fix it. You can also add some aloe to your water as well. 1/4 cup whole leaf blended or 1/4 teaspoon of 200x powdered per gallon of water. Aloe will help your soil become less hydrophobic because it contains Saponins, they act as a surfactant or wetting agent.

 

Thats super slow but i agree, slow watering is not talked about enough. personally when i top dress, i get the whole top wet, wait an hour or so, then slow water until runoff. ive got a fancy transfer pump with a showerhead that pumps about a half gallon per minute which i find to be just about perfect.

 

I'd suggest top dressing with around 4 cups of casting and 1/4 cup kelp meal mixed together for each 5 gallon pot. Your dry pockets can be anywhere in your soil mass. I've experienced dry areas in the center of the root mass and on the outside edges of the pot. It occurs most frequent with smaller fabric pots on the outside edges.

 

Your welcome ka_tet3tr. Alfalfa meal is usually found at animal feed stores or you may even try pet shops. I get mine from a local feed store. As for Kelp meal, we use ascophyllum nodosum kelp. Not all seaweeds offer the same nutritional value.
