Beginner hydro waterfarm problems overwater? ph?

Just transplanted this MK Ultra into the WaterFarm and now the leaves have begun to droop a bit, purple stems. PH was around 6.8 at time of writing, adjusted it to 5.5 For the first day I had the pump running 24/7, noticed the droop, (assume overwater), so today I adjusted the plant to get watered for 30 mins 4 different times a day. It has not been 24 hour since I lowered the watering time. Would still like to hear your opinion.The lights are 4 foot T8 6500k (My 600 Watt MH will be here in 2 days).So can you give me any advice on whats going on with this girl?

Looks cold.

Yeah the plant even feels cold, damn winter time. Put a small space heater in the closet and set the temp to 72F, we'll see if much changes overnight. Thanks

Yeah post an update pic, bet it perks right up!

She looks great no worries , just getting use to her new home. Where was she before and how much was she getting watered ? Just as long as the watering schedule has not drastically changed i'd say give her a few days. Good Luck.

Happy Growing!

Ok update pic, my 600W MH (22" away) came in today and I just put it up, plants have been under it for about 1.5 hrs in this pic. The room did seem to warm up nicely with the 600 haha, I do think it was a bit cold, avg was around 68 degrees day/ 65 night, maybe to cold. We'll see how she reacts under the big boy light. Thanks for the responses fellas!@cocakola the plant was in soil before she went into the hydro bucket on Monday (3rd day in the waterfarm, today being Wed).

Some of the leaves on the top are folding upwards like tacos too...

So I adjusted the pH from 6.8 down to 5.8. Abiemt temp around 88F, cant do much about that till my 6inch CFM comes in. Secondly I added a bucket full of water with a towel hanging out of it to add so humidity to the air, the relative humidity has been around 15%, would like it around 40% if possible, we'll see. Any advice is welcome, thx. I've been tinkering with my setup too much over the past couple of days, I'm gonna let it stablize over the next few days, just monitor the pH and adjust if necessary.

Ok, 5 days later and she is as perky as a virgin in a strip club. I just maintained the ~5.5pH, the timer waters her for 30mins 4 times a day, seems happy. Nutes are at 1/2 strength, will bump them up next week to full strength. I will be putting her into flower in about ~2.5 weeks. Thanks for the input.
