problem with sunflower leaves.
i use miracle grow potting soil to grow all my plants in my container garden.
my 3 sunflowers are about 2 months old and over a foot tall (no head yet). their first set of leaves turned yellow and shrivled up yet they were moist. so i cut them off because i read somewhere it's normal and that's what u should do. but now, the second layer of leaves on all my sunflowers are turning yellow too. one of them has yellow leaf tips with brown spots. another has yellow specks all over the plant like tie dye. and the last sunflower, has the second set of leaves torn and slightly yellow, with one of the leaves having a brown dry spot.
i repotted them about 10 days ago into bigger pots. and according the package, miracle grow feeds plants up to 6 months. i water the plants every other day because to me the soil feels dry by then. theyre in direct sunlight and i don't see any any larva on the leaves. this morning i did see a brown spider on one of them. could it be spider mites?
thanks in advance.
