Hi all i have 11 plants from seed on the go at the mo. 6 white rhino and 5 AK48. The Plants are just over 4 weeks old and were started with potting soil. they They have been potted up twice and where last potted up 2 weeks ago in biobizz all mix. I thought they would last for quite a while without ferts but have started showing yellowing leaves is this due to nit def.
On saturday night i gave them 1ml biobizz grow per litre of water. any advice is much appreciated.

read this mate its not a rule because all plants are different . but its a start

Cheers for the reply Jiffa.
Did have a problem with temps at first but sorted now 25-26 lights on 17-19 lights out.
Ive been water every 3 - 4 days when the soil feels dry/crisp on top but maybe a i should leave them longer ? the last watering was Saturday with 1 ml grow will up to 2ml next water.

shouldnt need it yet , do the pots feel light ? read the post by ot1 mate that will put you on track with the nutes

im not a soil grower and dont use biobizz someone who is will let you know what to feed them to bring them right
