I thought it was over watering but I'm not sure. It looks like it could be a phosphorous deficiency. Nute burn? the pots too small? Top looks pretty nice and green, whole plants a bit droopy though. What type of medium; soil or hydro? soil What brand and type of soil? moisture retention generic potting soil brand (dont have the bag anymore, need better soil) Indoors or outdoors? indoors What strain? sour grape How old are the plants? sprouted oct 6th What type of lights and how many watts? CFL's approx 5 of them around 30 watt each, 5000 to 6500k How far from the lights? about 2 inch, maybe a little more What is your watering frequency and source of water? RO filtered water, when the medium is dry about 2 inches down, worried about over watering so I've let it be dry for a few days What, how much and when was it fed? NPK? very sparingly was given very diluted nutes What is the medium/runoff pH and PPM if in hydro? dont have a tester yet What are the temps and humidity in the room? 60f 60hum What size pots? its a 2 liter Any bugs? Look real close. There was little white bugs and little orange crawling things, there was also fungus gnats, used h2o2 a few times to kill them.
You need a ph and ppm meter. to give you an idea of what 50 ppm will look like, 1/2mL of nutes in 2 gallons of water brings me from 30ppm (straight from tap) to 80 ppm. Using fox farms hydroponic grow big. You need very little to no nutes. Try using just plain old water for 2 weeks. The soil already has a lot of nutes, it might even be too fertilized with no nutes at all, and in that case your plants will die if they aren't transferred to "cooler" soil. Good luck.
Some overwatering for one...go by the weight of the pot, not by sticking your fingers in the soil. Also, what do you have for nutrients and how much/often exactly have you been feeding?
18-21-21 directions say 1 tablespoon per gallon of water, half a galon for a tomato plant shorter then 2 ft and 1 gallon for tomato plants taller than 2 ft. This is obviously way too much nutes, I used about less than half a teaspoon per gallon. I did give the big boy some of the nutes once it was older then 2 weeks, but I didn't think it was that much, I was also flushing and misting with h2o2 at the time to get rid of pests. Its either over watering, or too much nutes is what I'm thinking. I flushed her with two gallons of michigan city water. Some of her roots were also exposed, so I added some more soil. My other plant is starting to yellow on the edges of a leaf here or there, how should I combat it before it gets as bad as the other one? And also, its much worse than it was yesterday on the big plant, some of the leaves are completely yellowed with brown blotches. To finish up, i sprayed and poured about 4 oz of a diluted h2o2 mixture* on each of them to help oxidise and kill pests. * 1 tablespoon 3% h2o2 per 8oz water Is my best bet to get different soil and transplant both of them?
Between the soil that you dont know what is in it and the heavy feed they're likely overfed. Youve flushed with 3x's the volume, now let them be and give them a chance to recover. Next time get some more appropriate soil.
Did you cut the 2 liter in half? Talking about exposed roots, it may be time to transplant into a larger container. If so, you could gently wash away the old unknown soil and replant with good soil. Sent from my iPhone using Grasscity Forum mobile app
