THE TIPS OF MY LEAVES ARE YELLOW AND SOME LEAVES ARE COMPLETLELY YELLOW AND SOME BOTTOM ONES ARE CURLING! Wat up. I have 9 Master kush plants from feminized seeds off nirvana. They are 20 days old. I had 15 originally but 6 perished. I am using 2 600 watt HPS cooltubes, and Fox Farm Ocean Forest potting mix. The light schedule currently is 24/7. They are in 3 gallon pots. The average temp is between 75 and 80 degrees and humidity is usually around 30%. The temp sometimes jumps up to 85 degrees when the AC is off. I have watered them between 8 and 10 times during the twenty days. I have been judgeing when to water them with a moisture meter that i bought. The first few times i watered them just with a spray bottle. Now i water them with about 100ml of water. Is this too much or too little? I fed them for the first time 2 days ago with Botanicare Power Plant Nutes 3-1-4. It said to use 7ml of the liquid per gallon of water for seedlings, so that is what i did. I put exactly 7ml into 1 gallon of distilled water and gave each plant about 100ml. Was this too early too feed them? Have i been over watering or underwatering? Are these anyof the reason why my plants are turning YELLOW? Please help! i am very concerned for my plants. here are the pics

id say 1200w of light is very strong for them to start from scratch with and especially at 24/7 light,tone it down at bit,18/6 is all good

check soil bag or whatever for info,should say how much feed it has
