Questions about my plants. anyone please feel free to comment

ok so i didnt know where to post this because i have hydro and soil, but my concerns are mainly about my hydro setup i started the 4 indica plants 3 weeks ago the clone was added 3 days ago and is the largest of all of them. the clone is purple cotton and the seedlings are 21 which is a hybrid of blueberry x sweet tooth. growroom is a growlab gl120 4x4x6, my lighting is a 400w MH in a suntube, two 60w cfl and the blue 12in. t5. i have a 170 cfm fan cooling the MH and attached to a gremlin activated carbon filter. temp is about 80F humidity ranges from 40-65. my worry is the hydroponically grown ones i started them all in rapid rooter plugs but the only one to really grow is the soil based one. i feed them general hydroponics nutes in the ratios of 1/4 tsp floragrow, and 1/4 tsp flora micro per 2 gallons of water ph balanced to around 5.5 the npk ratios are 2-1-6 and 5-0-1 respectively can someone please tell me what i should do if anything?

The hydro ones are too light green and would benefit from a bit stonger mixture. I'd go with the regular veg mix directions. You should get the 3rd GH bloom mix and add that as well. I'd just remove those smaller cfl. They're probably not doing anything although you may have too many plants for the one 400 hps to handle once they get big. I grew 8 oz with just one plant and a single 200 hps. I bent the plant over and let all the side buds shoot up to full buds very close to the light.

I use general hydro also start your rooted clones at the ratio of grow 2tspn micro 2tspn bloom 1tspn then after a week bump it up to 3-2-1 I think you need more nitrogen

per gallon or whole reservoir for that ratio?
