lol are you a grower who uses red spectrum in veg? dont believe these growers telling you using red speck wont hurt your fem seeds! you only use reck speck or HID when first flowers start to show!
how many times do you feed them a week? how maney times do you hit them with water a week? RO water or tap.. i had the same looking problem with my plants found it was cal/mag deff one of the two i use RO water. i just hit it with some molasses in every feeding for a week and they jumped right...
lol can you feed compost when the plants need a certain vitamin or carbohydrate? composte only get threw the plant at a certain time you have to think pk spike and other carbs when wanting to get swollen frosty nuggs.
this all depends on what your growing in, all i grow in is soiless mix no nutes so when you grow from soil that has nutrients in it you have to wait till them nutes go threw the plant its all in what you know.
