First this is my first grow. I have no experience at all. I am growing 3 Auto Haze plants. I think I am nearing harvest. Many Trichomes appear cloudy. None are amber. They sprouted 11/3/22, so I am about 11 weeks out A few days ago I noticed light green leaves on two of the plants and darker on the other. Some thought it was a phenotype difference. It seems there is a nutrient problem. Now one of the plants seems to be much more affected than the other one. The other plant looks is getting a bit lighter. Watering has went well. Ph around 6.7 Rh 45-55% Temp day 72-80 night 62-70F Soil is a mix of perlite and used flower soil and Nature's Living Soil I use Fox Farms Trio about half recommended dose. I have supplemented with 1/2 tsp Epson salt, tbsp wood Ash and 2ml Mg/cal/ gallon for a few feeds during flower. Yellowing is mostly upper leaves and some mid leaves. Yellowing migrates from tips to base of leaf Minor burning on the tips. Stalks are purple but I noticed this months ago and this may be genetics. Ignore curling of sugar leaves top cola. These also had light stress. My thoughts are possible Phosphorus excess. I use 2-3 ml/ gallon of PH down which is Phosphoric Acid. I also gave them about 4 feeds which included tbsp of wood ash in water. This is supposedly 10% Potash which should give K+ and P+. I did read that Phosphorus excess is rare and it is hard to give too much. ? K+ excess for same reason. Maybe the Ash. Lower leafs I think should be involved and are not. Sulfur deficiency I have supplement w Epson salt so I doubt this and also the yellowing appears to begin near tips of leaves and migrate back the opposite of this appearance. Maybe I have a nutrient lock out from salts but I only feed 1/2 dose fox farms 1 or 3 x a week So far I have done a larger watering with no nutrients to help flush anything. I didn’t do a real flush because I'm not set up for managing all the run off water and don’t want to lose all nutrients in the soil but I very well may be wrong. I just gave them all a feed with the recommended Fox farm nutrients which is twice the concentration they normally get. Any one with any ideas? Do I really need to do a flush with gallons of water and get a shop vac? Should I ride it out? Should I harvest soon?

I am growing 3 auto flower Amnesia Haze. Started with auto flower because I thought it was better for a beginner. Now I'm not sure. We used paper towel method 3 seeds popped. 1 was a dud. We still planted it but it never popped. We initially planted in small peat pots in a seedling starter tray. Seeds were from seed supreme. We transplanted from early seeding to roughly 3 - 4 gallon ceramic pots. 1 hole in bottom. Never have gotten any run off yet. Afraid of over watering and I check soil w moisture gauge. We use Barrina 2000 fUll spectrum Led. It's 200 watt. Starting to push ppfd to 8-900. About 13 inch from top of canopy. We use low stress training. I cut some tomato metal cages smaller and we use small pipe cleaners for training. We planted around Nov 1 st so we are 6 1/2 weeks in. Used living soil and supplement with Fox farm trio. Give nuts about every other watering about 2 x a week. Also added a 1/2 tsp of epson salt to half gallon w 1 watering. Recently decided to try maximizing pH w sulfuric acid. Have a cheap pH and soil moisture tester and well water was testing a bit over seven. Now trying for high 6 pH. Added organic rev about 1 tsp with 3 waterings Also used sensi mal cag twice. About 5 ml altogether. Water about every other day Created grow room from empty closet in garage. I have a carbon filter And 195 cfm fan in a space that is 8x4'. Only about 3x3' is used for the grow in this space. Also use a humidifier. Keep temperature in the low 70s and try to keep humidity around 55- 55. In early veg and seedling I kept the humidity a bit higher. Anyway so far thing are going well in early flowering. may have gotten a little stress early w stunting. I think a stressed it a bit a couple times w too much light. A few leave curled a bit. Iverall happ at this time Currently awaiting an ec ppm tester because I'm not sure what they are getting with well water. Anyway just wanted to share my experience with my first grow
