Top leaves curling under

Looks like a bit excess of nitrogen, red stems could be genetics

 

Wow haven't seen anybody use coconut water in a long time. It is actually very good for plants and lots of nutrients. Try cutting the watering with coconut with 50/50 water to coconut water ratio for a week to see if that helps. Good job by the way, plant looks good.

 

Did you up pot size to the 5 gallon with fresh ff soil or did you start out in the 5 gallon cointainer?

 

Are you using the coconut water mix every watering?

 

Try using more water to get about 20% run off each watering for a week to help break down the FF nutes in the soil. If you tested your ppm run off i bet it is on the high side right now. I dont believe its the coconut water blend your doing since you already are diluting it. FF ocen forest can run hot, and help dilute the HOT side of the soil is to water with 20% run off till the run off ppms get to a desired level.

 

Nice job! It dont look all that bad really but i agree with what was already said,,i do have a question tho...when adding ur molasses do u just put it in cold water? If so try n use warmer water NOT HOT to melt it a lil that stuffs thick and can cause lockouts actually and by the time it can get fully broken down ur plant will be chopped anyways,,but can be good to add to super soil's that have to cook for few months

It wont give you a good range of ppm thats why FF ocean forest is labeled a HOT soil due to nutes in it. A lot of growers, myself included mix it with FF happy frog to make the soil less nute HOT. Watering with some run off will help leach the nutes out of the soil to bring them down so it wont be so nute heavy. Since your in flower you will need those nutes so dont leach out to much, just a few run off waterings at a time and watch the coloring and curled tips to see if they recover. Another indicator of your plant being nitrogen toxic was the deep dark green leaves.

 

If your strictly staying with a organic grow, then I would wait on filling the rest of your pot with fresh soil when your nutes in your soil get depleted. If you add the soil now your going to make the ppms higher and burn the plant.

 

Since your not lacking nutes the lighter color sometimes happens after your lights have been off, they should green back up in a few hours. Also the leathery, dry feeling is more than likely from the nitrogen toxicity. Just leach for a few waterings with the 20% run off, keep eye on ppm run off and keep watching how the plant reacts. Also leaching the nutes out with the 20% run off will rid the plant of the high nitrogen and the plant will loose the over abundant dark green coloring.
