Starting to see some light yellowing in between the leaf veins. Growing is promix hp. Watering with tap water ph'd to 6.5. Temps run between 75-78. Humidity at 75%. They are 11 days old, and have had a dose of Homegrown Cannabis Co's seedling booster that has an NPK of 11-40-13. Using AC Infinity's s44 Ionboard 400-watt LED grow light, at their suggestion for seedlings which is 18 inches at 40% power. Could this be the beginning magnesium deficiency? Or am I making a big deal about nothing?

Are you watering the whole pot?

Probably not. For their first real watering, they all got a 1/2 gallon of 6.5 PH tap water. Our water here has 185 PPM. I did get runoff, but only like 1/4-1/2 cup. Was trying to not overwater them the 1st time, and did notice some dry medium near the otter edges.

Over watering is watering to often. But when you water you should be saturating the pot

I'm pretty sure that I figured it out. My runoff PPM's ranged from 1200-1500. So I checked my nutes and I read the chart wrong. I was supposed to mix 4 grams into 8 liters of water. I mixed 4 grams into 1 gallon. Don't know what I was thinking. Maybe smoking a fat joint before my 1st ever feeding was not a wise decision. So I believe it's overfeeding. Glad the nute was a mild seedling booster or I might have been in real trouble. Flushed with PHed water until they read 550-600 ppm then gave them a light feeding after the flush.

just note for next time growing with promix hp, as long as you use organic nutrients, than you don’t have to ph or anything, there’s ph buffers in the promix..
i’m assuming your ph stuff is synthetic so you’ll have to use it the whole grow..
you also have some light stress, i’d raise it 10 inches more..

Even if my water is at 7.7?

my grows/cloning/starting seeds methods are pretty simple really.. and i don’t seem to ever have problems as long as i’m in control from the start..
meaning i’ve gotten infested clones before from a friend and had to deal with crap like that but otherwise everything else goes nicely and i don’t think i can make it simpler than it is now..

ok. is it ok if i add oyster shell to the soil or azomite ?

why? oyster is basically adding calcium.. azomite is good stuff,
do you have your own thread? as i don’t know all info on your grow..

I had read others who had done this and they have pretty good grows. no, i don't have my own grow thread. i am starting a new grow and have seedlings. i will start one and i'll tag you on it so you can see. thanks
