Hi all,
I am having an issue with my seedlings and I am not sure whether I’m overreacting or whether there is actually an issue. I am experiencing slow growth it seems and I have red stems and veins
My seeds started germ on March 31st and were planted on April 3. I’m in Roots Organic soil (in my solo cups) and a mix of kind soil and roots organic in the big pots (less important right now). When only running veg lights, I was between 70-74 F for daytime temps and for the past two days running veg and bloom lights, have been between 73-77. Nighttime temps hover around 65-68. RH has been between 60-75 depending on the setting of humidifier. Usually daytime RH a little higher. The water that I’m using is well water with a PPM of 53 and hardness of 28 mg/l, calcium at 9.1 mg/l and magnesium at 1.4 mg/l. PH is 6.66 out of the tap but I’ve been keeping water by grow tent over and using that water which was 6.62 when I tested.
I am running an 1100W LED at 18” with both veg and bloom going giving off a supposed 600 par at that distance. I don’t have a light meter to test. Actual wall draw is 120w on the veg lights and 240 with both veg and bloom going. Currently running both (last two days) but for the first two weeks, only running veg lights (at distances of 18-22” - started higher and moved closer over time).
My inclination is that this is a mag deficiency, may cal as well, based on the very small amount in my well water. But shouldn’t the seedling be well fed in the roots organic soil? I have been pretty diligent about not overwatering and started at once per week and then upped to twice per week. I stick a finger in the soil about an inch down to test the dryness before watering. I just watered again yesterday and my runoff was 8.1. Any thoughts or am I overreacting? I have some cal/mag and PH down (55% phosphate derived from phosphoric acid) on its way to me. Is there anything I can do in the interim? I am considering just transplanting them now in the bigger pot with a scoop of kind soil under the root ball. Will that help? Any and all suggestions would be greatly appreciated.
