Hi everyone I was hoping someone could help me with my seedlings they are about 3 weeks old and growth was stunted because im pretty sure the light was too close, I pulled the light back and now they are looking better. One has shribbled leave and its cotyledon have pretty much died off, I was wondering if I should give it some weak strength nutes to pull its self through or is it too early? the other one is droopy has purple tinge on the ends of its leaves and also has a stain looking thing on one of its leaves. I have another 2 but they look pretty fine. I think they also could be shribbling because i was bringing in cold fresh air, direct from window? maybe thats what has caused the purple tinge?
i usually flush my coco with a light calmag feeding and drop or two of superthrive and then plant when coco is really moist and wont have to water for almost a week with light misting.. then just water the root ball with ph'd water (5.8) when coco is lookin too dry
I usually start giving my seedling nutes at about this stage(when I see the second true set). I personally do 1/4 str solution which would be about 1.5ml micro, and 2.25ml bloom with 2 ml calamg per gallon. ph'd @ 5.8 adjust accordingly
Can you give more details? What kind of coco - brick or bagged mix? How are your temps? Humidity? What's your water schedule and how much water are you using for each plant? Are you measuring the PH of your water? What kind of light are you using?
