@hazer7, they look very hungry. When a plant is short of nutrients it takes the nutrients from older leaves and uses it to make new ones. All those dying yellow leaves at the lower part of the plant means she is really hungry. You can see the same thing on my "Enigma" diary - I cannot feed her enough because she is in a tiny pot.
Your plants need more food I believe so.
@UnorthadoxDude, i saw it your enigma seems look a bit funny xd. thanks for comments i was feeding them with half scale for last two weeks. i uploaded new photos you can see they growing so fast to up. i have no more vertical area for them
