I apologize for the bathroom pic, but it was right there.

I think it looks fine though you may want to start feeding nutes. Ocean Forest will last about 3-4 weeks without needing anything. But looking really good otherwise 👍.

[AFsingledad]

I just started adding Nutes today and half strength and it is the end of the 4th week. I see some pistols coming out on both plants. I trimmed a couple of the really bad leaves off the one that's rough. Its not on all the leaves, but maybe a quarter of them this is what I am seeing. Wanted to be able to take a good picture. Again the other plant looks fine. Could it be this one shot up so much faster it was wanting/needing more nutes? I take this as a positive thing that I have two plants not doing the same thing. This first grow I am just trying to learn as much as I can from the community.

If it's starting to flower it will definitely be using the nutrition in the soil. There's not a lot of p or k in ocean forest they need some bloom food.

[AFsingledad]

I can see that and thank you. The nutes have helped.

[AFsingledad]

My healthy girl up front. I think she looks good.

Day 28 and 2nd feeding of the Fox Farm nute trio and they are responding well. I went at half the recommended dose and they appear to be doing alright so I may keep that dosage unless I see I see some issues. The problems I had with the one appear to not be in the new growth so hopefully it worked itself out. I took the humidifier out and I am sitting at 45-50%. Looks like uping the PH to 6.5 and giving some nutes helped out tremenously.

[NAKEDGARDENER]

I would keep the nute level as it is, honestly I do same with the ff nite trio and also keep feed at around 6.5 nd they too are thriving and in week four of flower. Keep it up, they doing well.

[AFsingledad]

Thanks. So far no deficiencies, but she is starting to explode and flower now so I worry. I plan on keeping it the same unless I see anything that concerns me.

[AFsingledad]

Can someone tell me what they think these brown spots are. Only thing I can think of is calcium deficiency to many nutes. I am into week 7 and week 2 or 3 of flower. I been feeding the Fox Farm trio and didn’t start until the end of week 4 once I saw pistols. I also added CALMAG at beginning of week 6. Now I have brown spots popping up in the older/larger leaves halfway up the plant. The spots seem to be more along the veins of the leaves. I did notice very light-yellow tips on some leaves which would indicate nute burn. At this point I don’t know if I need to add more CALMAG or do just PH water in case I fed to much. This is my first grow. She is a little tall and skinny because temps were low to mid 80s a times during veg and light may have been a little far. You live you learn.

[AFsingledad]

I used nothing until end of week 4 and then I used all three. for 4 feedings/2 weeks. On the last feeding, I cut out the grow big. Is it because I used the Grow big and shouldn't have?

[AFsingledad]

I know the FF had enough to get me through 4 weeks so I didnt use anything. Last feeding week for and into end of week 5 I used all three. Week 6 I cut out grow big and added some calmag. End of week 6 I noticed spots and now its week 7 and I just gave water.

[NAKEDGARDENER]

Grow big leans toward more nitrogen and is more for veg state after switching I stop with grow big and focus on phosphorus potassium leaning nutes, which is more for bloom. Also I lower my ph to help deliver more iron and other minerals which seem to be better taken up at a ph of say 6.30 . There is something about those spots on Gwe site but I can’t load it on my phone right now.

I am stumped. I did add some bone meal a couple weeks ago. Probably pointless considering it takes a while to break down. Then week and half ago started adding CALMAG. Don't know it it could even be calcium. This also started with the two largest middle fan leaves and slowly is going to other leaves. Nothing at the top yet, mostly in the middle. I am stumped at the moment what to do. Starts off very small yellow and brown dots on veins. Most spots are on the veins.

Well, I did a full flush. I think possibly I had too many nutes. Since doing the flush a week later it has not spread anymore and buds are fattening up nice so I think I am ok now. I switched to Bloom only.

[NAKEDGARDENER]

AFsingledad, I forgot which week you are in, I too had to flush mine, since my ph had got low due to the nutes I had been using, all I use now in week 8 is molasses and PhD water at a ph of 6.70. Have you done a ph run off test as well recently?

[AFsingledad]

I just finished week 8. I did a flush and she is looking almost ready. So I think maybe end of week 9 I will be harvesting. I just flushed with PH'd water and giving it water only this next week if needed. Even after I flush and after I got a 6.5 run off a few days later it was back to 5.8 or so. Something with the Fox Farm the run off is low. I heard if you check the actual soil it is different and has something to do with the buffers in the soil. I am not sure. I don't think I will be using FFOF on the next one. This all caught me by surprise because I thought it was a 90-day seed to harvest, but this is going to end up being a 70-74 or so seed to harvest.

[AFsingledad]

I am on day 56. about a quarter have turned to amber. Trichromes still look all clear. I know I am getting close to doing a flush or hard water only, but questioning when. I may just be days away until. I have heard when have the hairs or whatever are amber and trochromes start to turn cloudy. Then do the flush.

AFsingledad, beautiful pictures.
She still looks like she is still growing to me.
