Hello moving into veg stage. Im a second time grower indoors. Have 4 Gorilla glue #4 in soil. Moved out of small containers two weeks ago. Now in slightly larger than 5 gallon. Soil is mixture of FF ocean FF frog Schultz top end potting Schultz top end top soil and perlite. Translate went perfect and they started to take off. Two weeks ago three days after reporting I started the first and only dose so far. Was FF wholly Mackerel and B-52. I used A third of recommended three days later a small drink of plain water. Then when I water I put 3 or 4 drops of Schultz plant food recommended is 7 drops. As you can see they started to take off but the last two days they haven't grown and the stems to water leaves has turned purple red and the inter veins of the leaves are red. The main stock only in upper section has purple red running vertical. Ive tried looking it up but not having much success. Any ideas
