20 years the same way .claening ,etc ive done all of that ....thats why imfreaked. if i dont use kool bloom right away,,,buds never form...it just keeps growing like its in veg. this is probably the 4th time ill be starting over .....i had clones going in the 3 " cubes ...then when i put them on the slabs the roots turn brown and die. ive always had slight dificulty in fwr but never in veg ,,,now i do. thats why i went to the DWC. hopefully a new system will work. i was told ive been overwatering. through this whole thing my roots have been terrible. there have been timesin the successful past that the roots came out of the bags right into the res. maybe ive just lost my green thumb
