Hey Guys, I really need your help. I'm a first time grower. I have 20 G.S.C (18 days old) in SOLO cups (with drain holes) in a 5x9 grow tent with an 800 PhytoMAX LED light from Blackdog on a 18/6 light cycle. I'm growing in Fox Farm Light Warrior Seed Starter. When I first planted the seeds I watered the soil with PH'd RO water and added 'Root Enhancement' + 'Zym' (Pure Essentilas) to that water per manufacturers suggestion. Someone on this forum suggested that I stopped using nutrients and RO water since it was stripped from micro nutrients. Following his advice I decided that next time I watered (I used the cup weight method) I would do 10 plants with PH'd tap water and continue the other 10 plants with the Pure Essentials nutrient schedule to see the difference in growth. Everything was looking good after the feeding then 3 days later some of my plants stated dropping and started getting brown spots on their lower leaves. I wasn't sure why this was happening but after doing some reading online I thought it could be overwatering (drooping leaves) or underwatering ( drooping leaves plus browning). With that in mind I decided to water only 10 to see which of the 20 would recover. The 10 that I watered seemed to plush up the next day but the brown spots and yellowing leaves continued. Now they're back to drooping again with the same leave symptoms and spreading to next top leaves. I don't know what it could be anymore. I don't think it has to do with under or overwatering. Nutrient burn? but 10 of my plants I stopped the nutrients and they're getting the same leave symptoms. PH problem? I have a PH meter and ph all the water I use. Calcium deficiency? Tap water has calcium in it doesn't it? Nitrogen deficiency? I'm assuming the nutrient schedule that's telling me to add this, this and this on week 1 of vegging would have the nitrogen ratio that a plant in week 1 of vegging would need? Should I flush all 20 of them? Transplant to different pots? I don't know what to do and really want to jump on a solution ASAP Can anyone point me in the right direction to saving these babies? I've attached some pics on they started browining and how they're looking now Any help would be really appreciated, Thanks!
Ur plants are 18 days old? I would get them out of solo cups and into bigger pots. I am working on my first grow also and after 2 weeks or so I noticed my plants were not looking so great getting them into bigger containers made a huge difference. Not positive that your problem is the cups but transplanting them into bigger containers def won't hurt. After transplanting mine looked much better the next day
I'll give it a try. Do I keep using the same soil?(Fox Farm Light Warrior Seedlings Starter) I have a bunch of Vermifire soil that I was planning on using when I transplant. Sent from my SM-G925T using Grasscity Forum mobile app
I'm not sure I used FFOF from day 1. But as I said this is also my first grow, but my plants looked way better once I transplanted them. Mine were dropping just as bad as yours though and transplanting turned them right around.
