Have a troublesome grow indoors. First grow since 2014. Did 2 dry runs with 6 inch plants through flower. Seeds were from 2010 black market cannabis. Plants looked perfect the entire way. In fact lower leaves didn't yellow at all through to harvest, but they were tiny plants in 2 gal containers.
I started some plants from a seed bank. Bubblegum and Super Skunk. Grew them mostly outdoors in soil for the first several weeks. (It was a bad situation because, while my black market plants were all the same size, as with every grow I've done, these expensive seeds weren't. All different rates of growth in the same environment.)
Eventually transplanted the bubblegum (4 plants) and super skunk (2 plants) from soil to coco to grow outside in an extremely hot environment (Average 110F for two weeks x 2 episodes). Plants were transplanted to 10 gallon containers prior to the high heat assuming they would finish outdoors and so I could water heavily during the hot spells. Plants had one episode of yellowing leaves outdoors, possibly due to a phosphorus deficiency caused by too much sun) that appeared to be remedied by strict control of PH (5. and adding Flower Fuel (1-34-32) to the VPS products I was using at the time.
Unfortunately one super skunk and one bubblegum started flowering a few days after the longest day of the summer (with over 14 hours of light every day), and a month before I thought they would start, so, because of our monsoon season and knowing bubblegum molds, I moved all 6 plants indoors.
Now the plants are in a 4x4 in 10 gallon containers. Using a VS KS5000. About 12 inches off the canopy and set to 100%. PPFD is over 1000. Plants were trained to create a horizontal canopy and even though I lollipopped, the canopy is still thick, but light is reaching leaves that are now turning yellow, where as a week ago only leaves way down in the canopy were yellowing, and that appeared to be from a phosphorous deficiency.
When I started noticing a possible phosphorus deficiency fairly quickly in the tent, I added Flower Fuel to VPS again (PH 6.0) and fed that for 3-4 feedings. Nothing changed really, except the leaves didn't appear to have the previous brown spots on yellowing leaves.
As mentioned above, now I have leaves receiving light that are yellowing, but the latest leaves do not appear to have a phosphorus deficiency. Looks more like it might be a nitrogen deficiency. All 6 plants are at a different stage of development. One Super Skunk appears to be in about week 5 and the first to flower Bubblegum looks a week younger. The rest are in weeks 2-3.
So, before I loose this crop after all the work of getting them this far, thought I would ask for help. I did turn down the KS5000 to 75% to see if that would help. PPFD is around 600 to 800.
Added Co2 via wine yeast and sugar water a couple days ago. Do not have a CO2 meter to measure CO2.
Do not have pictures. Will take some when lights are on again.
I just want to say...WOW. That is a LOT of moving and some complicated stuff. I have to say, I think most people make growing this wayyy to hard. Harder than it ever has to be. My plants (3 different strains) which were started together were all different sizes when planted outside. No big deal, now that we are toward the end of Veg, even the smallest plant has caught up and is incredibly tall. We have some 9 ft monsters after I topped them throughout the grow. I make sure that when I plant them in the ground they get the best start. I amend the soil w the best organic ingredients I can find.. After that I feed 1x a week, slowly increasing the strength & amount I feed as they grow. It all works out. I just trust the plants.. If a plant has a problem, I try feeding that ones a little more and waiting a week to see the change. It has worked wonders. I'll attach pics. I learned from growing a veggie garden for many years about plants. At the end of the day this is a plant, and a pretty forgiving one too. I don't ever check ph or anything. My veggies grow well here, I amend my soil w compost at the end of the year and prepare for next year. If peppers and tomatoes like it, cannabis will too. That's what I have found. I use a dry feed and cal mag...that's it. PICS Below: we have small autos in pots growing along side our photos in the ground. Planted at different times, so we have different harvest times. The very large plants were first plants to be planted in June, they were tiny.. now some are literally over 9 ft..even w toppings...
