there just hungry! there almost a month old and haven't eaten yet, give them a 5ml per gal dose of the grow big to start and they will perk right up. i always used the ff products as well. BTW liquid karma and thrive alive work great when used together with the fox farm fertilizers. also with the grow big and especially the tiger bloom you will have to use ph up to bring the water/ferts ph up to 6.0. the only problem i have found with the ff products is that they are WAY TOO ACIDIC to use without adding some ph up. just my $.02
