Well, you didn't say how much and often on the foods but more than likely that is the ever prevailing cardinal sin of cannabis forums that is acting like the devil.
Good luck,

When they were in solo cups I was feeding full dose recommended at 2-3t gallon on the Grow and started to mix in some of their organic big bloom, which is more like a plant tonic, at 1 Tbls per gallon. They were lovin it with lush green rapid growth. As they were in the solo cups and 5 weeks old they were thirsty so I had to water daily - feeding every other day.
Once I transplanted to the FFOF soil amended with 1/3 perlite did I start seeing problems. Here's my thought, they were already so loaded up with ferts that when I transplanted to the soil with nutes in it it was just plain overkill. Also, the roots were a bit bound and not the vibrant white I was looking for after being in the cups for 5 weeks.
They are recovering it seems now and most are 12 inches under 18-6. Do you think I should wait a bit until they can spread their roots a bit before flowering or will the 16ounces of roots they currently have suffice for the beginning of bloom and additional synthetic bloom nutes ie Tiger Bloom and Open Sesame? They did develop quite the root system in those cups - it was a solid lb of roots in each. I have watered them twice in the last week since transplant and they are in 2 gallon containers.
I am still seeing browning on the leaves on some of the girls older growth, new growth looks good.
As always, thanks for your support my friend.
