Need Help Diagnosing Plant Problem

Hello. I have been trying to figure out what is wrong with my plants for a few days. After research and a lot of time I still have not been able to fix the problem. After researching online my plants look similar to pictures I have seen online of Phosphorus problems. I just wanted to see if anyone can take a look at my pictures and give me their thoughts. The temperature averages around 78 and humidity in the mid 50's. I have recently flushed my system and haven't added any new nutrients yet. The problem still exist. Thanks for anyone's thoughts or suggestions.

Could we see some pic of the whole plant?

Looks like the ph is off balance.

Ok. Here are some pictures of the plants.

these look like some larger clones that you have transplanted recently correct?

They look very similar to what mine are looking like and i am trying to figure out what is wrong. I may have a PH of about 7.3 which i think is causing the problem, i need ph down.

(but i am a first timer so i have no clue )

Yes the plants are recently from clones.

My ph is normally around 5.5 to 6. From what I have gathered that is the range for the ph in an aeroponic system.

Both of you, we need to know what you are using for nutes, More or less everything you use and do would be helpful. Thanks

The plants are in a 4x4 ft grow room. I have an aeroponic system that has a 5 min cycle timer. I currently have a 144 3w led light. The light cycle is 18/6. I have a fan that runs to circulate the air flow. I have a an inline fan hooked up that sucks out the hot air. The nute I use are general hydroponics flora grow, flora bloom, & flora micro. As far as the nute amount used, I use the recommended dose per gallon for the vegetation growth.

be careful with fresh planted plants apparently. I have heard it is better to start off with 75% the recommended dose at first, and slowly work your way up to what the nutes recommend, (you can always add more nutes, its hard to take out)

I dont want to steal this guy's post so i wont talk more about mine, but i managed to get my ph to 6.5 somehow, the water naturally went to it. I hope they pull through, its like having a sick baby =\ you worry.

Hmmmmm OK what are the water temps and you are mixing the nutes correctly by not mixing them all together at once ?

Looking at the whole plant its seems to be on just a few leafs but starting to make its way though out the plant. Make sure you PH is correct you want it at 5.8 but 5.6 -.6.0 is ok. Do you use hydrozyme? if not get some you should have some in your system at all times. If these were my plants I would foliar spray micro 1/8th tea per quart everyday until things change also when you are at the hydro store pick up some seaweed extract and rotate the 2. If you ever think about changing nutes try dyna gro its clean and easy and works killer on hydro. Thats all i got man keep us updated.

imo its K def. Try just flowering nutes for couple of weeks. If it is a k def ,plant will be dead within a month if u dont correct it.

Thanks everyone to all your input. I have since did a new flush, added recommended nutes and mixed the nutes correctly. Hope they turn out ok. I think after sparkafire recommendations they will turn out fine. I have ordered the hygrozyme, seaweed extract, and dyna gro. I have done research on all 3 products and wish I would of been using these a long time ago based on reviews. Thanks again.
