Is it too early to trim all the water leaves off except for top 4? The large water leaves are effectively blocking light.
I would defol the bottom of the plant. Clean that up and it’ll make some space between the soil and the leaves. Make it easier to water too.
@Growdoc plants are doing well for the most part. Last Sunday I noticed they were getting light green. I realized I was not giving the correct amounts of big bloom. I refilled the reservoir with I gallon for week 4 of the fox farm feeding schedule ppm 1100 ph 6.8. I started noticing some things and wanted your opinion on what it might be.
What soil is that in and do you have any real life runoff numbers?
That is fox farm ocean breeze. Self watering it has not dried out. The bottom 2 inches of the pot is damp. The girls are drinking a gallon of water every 4-5 days. I wash the basins and fill with water and week 5 of the fox farm feeding schedule. I was shorting the plants the first 2 feedings. By 50% of the big bloom. Sunday Morning I gave the correct amounts ppm 1100 ph to 6.8. I have not top fed these plants in weeks. How should I proceed with getting runoff using the self watering system? Using these pots has taught me that I was grossly underwatering in my prior grows. To be truthful I don’t understand watering to run off. Is it 1gallon of water ph to 7? Pour in pot till you get about a cup of runoff to get real readings? I’m getting very frustrated.
Runoff numbers consist of watering to the point that some water drains thru the bottom of pot, catch that and test for ppm and ph. Self watering bases don’t typically have any runoff.
Nice looking grow you got going @tangman I agree, they do look hungry, which you’ve already identified and increased the ppm’s. I’m not sure when you last fed them, it can take a few days to see improvements. Look to the new growth.
When I watered to run-off with Fox Farm Ocean Forest soil, my run-off pH runs high. I have different parameters than you and all effect the final pH of the soil. I would try to keep the pH in your bases as close to 6.5 as you can. PH above 7.0 can start to lock out nutrients. I’m seeing what could be a little Ca deficiency happening maybe, not sure. And are you pHing before or after mixing your nutes, cause you want to do it after. 
Here’s a pH guide. I have a better one somewhere but this is all I could find at the moment.
Here’s another:
You probably already had a pH chart beings how this isn’t your first rodeo. I was just cautioning from my own experience. My run-off pH kept running high so I was putting in low (a couple points lower than the low end of the range) in an effort to drive the soil pH down. Not only did it not work in my case, I introduced other problems as a result. After investigation, I found the actual soil pH was not as high as the run-off pH and I was chasing a problem that didn’t exist.
So this is the first time using self watering bases, huh? How are you liking them so far?
It taught me that I wasn’t watering them enough. For that alone I love them. They drink what they need and so far I don’t have to let them dry out. They get a fresh solution every 4-5 days. I read somewhere that I should add some hydrogen peroxide to the reservoir. I’ll try to post pics each week. I plan to give them a good trimming to expose the bud sites underneath the water leaves. The interior of the plant is too dark.
You don’t generally flush bottom fed plants except in emergencies. Algae is no big deal, I got it on mine now. Only the tan bags though, black don’t have it. You may want to throttle back on your ppm, 1200 is on the high side in auto waterers, it tends to run a bit higher than input, and so does ph, I have to mix mine at 5.5 to get 5.9-6.1 at the pots. You may need to adjust for that if your running a res, or are you filling each pot by hand?
I fill each reservoir separately. I found my probe and went from top of pot to middle and found what you talked about. The ph was just over 7. #3 and #8 will be ready for a clean refill. Will PH as recommended
. I plan to turn to flower in a couple weeks. They are as tall now as they were my last grow. I am considering going full hydroponic. Looking forward to recommendations to prep for flower.
16 days since flipping to flower. Girls have been drinking a gallon every 4 days. On week 8 FF schedule with bud candy added. 1100ppm PH to 6.1. @Growdoc @d-Jawz @BobbyDigital
Looks like you got things dialed in. Those ladies are showing they really have been liking what you’ve been giving them, that’s for sure!!
Looks like a couple of the strains want to be a little stubborn about showing their buttons, huh? Great job, growmie! 
Day 31 flower and some issues of yellowing leaves and burnt tips. Washing reservoirs and giving a fresh supply of nutes PHd to 6.2 usually solved the yellowing in a couple days. Now it seems it’s not helping. Plants 1, 4 and 7 are yellowing even more with 4 and 7 not consuming much water. 2, 5 and 9 are nice and green with 3,6 and 8 starting to get a lighter shade of green. Looking for help here to figure out why the 3 are yellowing so much? What can I do to stop the yellowing? @Growdoc @Lostgirl
I’m still learning auto bottom watering but I’ve only gotten them to 1.6 EC in the res for Autopots, your feed strength could be causing some nitrogen lockout from the looks, but you might need to do a slurry to get some idea of minerals in the media. Even at 1.6, I had painted nails.
I have absolutely no experience with Auto pots or bottom feeding etc. so I’m the last person that could assist in advice on that aspect.
Looking at your leaves it could be several different things. It’s definitely having a nitrogen fit in my opinion. (Lack thereof)
I don’t know if you paid attention but normally a nitrogen lockout will start consuming nitrogen from the leaves starting at the bottom working its way up and it happened super fast.
1.) If you’re looking at a nutrient lockout such as nitrogen you want to look at your pH both in and out and dial it in.
2.) look at your supply of nitrogen in both N & calcium that you’re feeding make sure it’s adequate to its daily consumption need.
3.) excessive use of magnesium and or Epsom salt. There’s a thin line to having enough and too much magnesium. Magnesium will lock out nitrogen went over used in a heartbeat.
4.) check your metering device and be sure your calibrated perfectly.
5.) be sure you’re not over-watering. This can create root issues that lock out as well. Good watering practices always a must
In my non professional opinion those are the top 5 things I would concentrate on checking as any of the four will cause total yellowing from lack of nitrogen to your plant
Sorry I couldn’t be of more help
I ph’d #7 reservoir and found the ppm at 545 and PH at 6.7. #4 665ppm ph 5.74. I watered these plants at 1050ppm at 6.2 ph 4 days ago. Not understanding why one ph went up and the other down. Getting really frustrated not knowing how to solve why 1/3rd of the grow is having issues
Different phenos will do that sometimes, if your ppm was near 500, it seems to be hungry. What media?
