    Hey guys first time closer grower here. Got 2 girls that are 6 weeks old showing some serious discoloration leaning toward nitrogen dificency.

    There in 1 gal pots with vital organics soil(local shop makes it) transplanted 4 weeks ago. I've been feeding them every other water using Botanicare mainly. Last feeding was a little under a week ago and I upped there nutes to 8mil growth 2mil karma 1mil hydroguard and 1 Mil bloom. Just flipped them to flower as well.

    Temps have been around 75 and humidity at 60

    All ears to any ideas!

    I think you may be feeding them too lightly and too far apart.
    Or that soil doesn't have enough nutes on its own.
    Either way it looks hungry.

    1 of the first tell tale signs of N Deficiency is Yellowing of the Leaves, from the Bottom Up.

    I like to use 1/5 concentrations of nutes, and water every time. Also make sure PH is good.

    Id also think about bigger pots, that looks like it has potential to be a nice plant. Nice short internode spacing. It just needs attention.

    I don't use those type nutes so I cant comment on them, oother than I like to use weak mixes, and feed each watering, or maybe skip feed the 3rd, Maybe, depending on how they look.

    Thabks Jim. Did forget to mention that I was phing to 6.5 after nutes were added. I agree with pot size as well! Got a feeling it's N dificency. Just wanted to make sure it wasn't nute lockout. Before I start adding more nutes

    The 2 girls in the left are in 3 gal rest are in 1 gal. All planted the same time. Remarkable what 2 gallon difference in pot size will do for your girls!

    It looks like a Nitrogen difficiency to me, but I definitely agree with the above posts about feeding too lightly, and a bigger container for your plant.

    Im feeding them to lightly? Doing quarter strength of what's recommended by Botanicare. Should I step it up to half stregth? Or more? Don't wanna burn the girls

    How often do yo feed at 1/4 strength ???? 1/4 is not much more than the 20% recommendation vs manufacturers recommendations. As I said, once they are really growing, I use 20% solution, and feed most every watering. If your watering 2x a week, but feed 1 time, I would try 2 feeding, and then 1 plain water, as yours is 5% stronger than I use vs fert recommendations, and I sometimes skip the 3rd feeding in a row, but that's also not set in stone. If theyre growing well, not sign of burn, I may feed 4-5 times before plain water. Also using smaller containers, will probably make the salts build up faster. I usually use 10-20 gallon containers per 1 plant

    The nutes I use recommends 1 TBSP per 1 gallon water, and water every 2 weeks... I use 3 tsp x 5 gallons water, and feed everytime, or as needed ect.

    Jimi has good advice.
    He's even a little lighter than me.
    I use 1/3 strength every day with plain water every 4th. Always water to 20% runoff.
    Occasionally skip a watering day and dry them out.
    Your plants need more food.
    It looks like your soil is depleted.

    My schedule has been quarter strength every other water. Finding myself watering them twice a week as well.
    Great advice guys. I'm going keep my feeding at quarter stregth and double my feedings. Also grab some nitrogen supplements asap.
