Hey y’all just joined so I could figure out what’s going on with my first grow.
Im on Week 5 with my six autoflowers (3 different strains; lemon pie, strawberry pie, orange sherbert)
They’re in soil mixed with coco, perlite and organic dry amendments.
600 watt LED (currently at 75% intensity and 50cm above the top of the tallest plant)
2.5 gallon fabric pots
I’m using two small humidifiers because without them the humidity is about 30%
A couple weeks ago I noticed the leaves were curling up so I figured it was nitrogen toxicity (I put a lot of the auto grow living soil which is high in nitrogen, just dumped it all in the mixing tub instead of measuring the 2 tablespoons per gallon).
To remedy this I added a lot more coco coir to the top soil. This made it seem like the soil was always moist so I didn’t water for a long time. I also read online that curled leaves could be caused by overwatering.
I used to water 300ml every 2-3 days in veg.
Once they started pre-flowering I upped it to 500ml but now I had extra coco and thought they were overwatered so I’ve been waiting 4-5 days between watering.
The bottom leaves started to turn yellow and I took them off. The plants seem shriveled up and much smaller than before so now I’m thinking they are UNDER watered instead.
Today I gave them all 1 liter of water and I’m hoping things will improve.
I also used an epsom salt foliar spray a couple days ago. Maybe I put too much.
I feel like the first 3 weeks started off great and they were thriving but now they seem so small and flimsy looking.
I probably should’ve took these photos before removing all the yellow leaves but there were about 2-3 large leaves per plant which looked yellow and droopy so I removed them.
I also included the Max and Min hydrometer stats in the pics. The humidity got really high last night because I left the side of the tent open it’s not usually so high.
What do you think the issue is? Underwatering?
