im on my first grow running 250 watt mh lamp in a small tent intending to grow 2 plants. iv germinated about 6 plants (just incase i screw up) but now i dont know which ones to save. a few have yellow spots on the new leaves and im worried they will be the weaker ones. im unsure why theyre even there it seems strange they would need nitrogen after only being in new organic soil for a week. opinions? could they actually need nutes already? sorry for light feedback and blur on pics
im watering about every 12 hours at this point which seems a bit much but the house is pretty humid at the moment and its hard to control.
well, i wouldn't worry about it. you're not doing anything obviously wrong so it may just be due to the complexion of nutrients in the soil which would have a more pronounced affect in the early seedling stages.
its called debco organic mix doesnt have any good information of the packaging besides saying PH balanced. im trying not to overwater but the soil drys out all the way down so quickly
Then transplant to larger containers and they won't dry out as quickly. Top dress with a worm castings "slurry", vigorously shaking enough worm castings in a small amount of water, leaving the castings sitting on top of the soil. When they get 6" to 8" high, feed them with kelp meal teas once a week, making this by soaking a quarter cup of kelp meal (not extract - kelp meal) per gallon of water for 3-4 days to several weeks, stirring occasionally.

fantastic thanks for the advice. a few of the other seedlings are showing more severe signs of yellowing and the weather here is about 33 degrees C which is pretty dam hot so i might invest in a few more fans maybe even put the setup in a cooler room will update with pictures when iv transferred them into new pots
i couldnt find ANYWHERE that sells kelp meal or worm castings in fert or anything (tried a bunch of agriculture shops) but while i continued the search i put them in new pots and used blood n bone organic fertilizer and it has helped alot. theres a few spots on one of the plants but apart from that they're doing great from my knowledge.
