Sproutlings started very well. Not much growth after transplant. Please help!

They're probably more like 15x30" holes

Your bed sounds well made... so hopefully it proves to be a pH problem... which should be simple to fix.

All plants have grown less than 1" in height in last 3-4 weeks. What should I do?

You transplanted too early and they got stunted. For your medium, take a bunch,thoroughly wet it and then squeeze some in your hand,if it doesn't easily crumble apart or it tends to stay in a clump,add some perlite till it falls apart nicely. You may have to water more often at first but the roots will grow a lot better and you limit your odds of over watering too

Well water absolutely must be tested and most likely diluted before using for growing marijuana.

Can Well Water Hurt Plants?​

Sodium, fluoride, iron, or nitrogen that are within natural ranges can kill your plants in well water, if it contains these substances. A regular watering practice that relies on hard (calcium and magnesium rich) soil has the effect of destroying plants.

Strip on left is soil water, strip on left is just water..

 

[Joey518]

Strip on Right* just water..

pH is upwards of 8.5..

When we do outdoors grows in Maine we dig the hole then add potting soil not the dirt on hand, we start in solo cups in April we put out 2nd week of June, the dirt is rocky and not much good for anything but potatoes, so depending on strain we dig hole and fill with FFOF and a bit of perlite witch they have been in since day 1 and are used to, small strains are transplanted into 5 or 7 gal nursery pots, large plants we dig the hole. Pic is a plant we put into a hole last year.

pH is upwards of 8.5..

Yeah, *way* too base. The water pH range we need is between 6.0 and 7.0 -- when growing in soil.

Once you get the water pH in range it should solve problems. To that end, we fill 5 gal buckets with water and let them sit overnight (water pH changes with exposure to air), then the next day we test and manage pH with General Hydroponics' pH Up/Down (or Clorox has a Spa pH Up/Down product that we have used too).

Also, it's important to get a digital pH meter - a decent one will run you about $70-$100 and give readings to 100th (i.e. 6.85). You are going to want a much more accurate reading because of how important managing water pH is... especially when you start adding fertilizers.

For now, strips can help get you out of the "rough" and back on the "fairway"... but you are going to have a hard time adding pH Up/Down at each watering because all the testing done between adding it a bit at a time to bring pH into range... this is another reason a digital pH meter is a 'must have' tool.

So do you guys think these babies can pull through or should I just start over? I dug out around the root base of all of them to help with the drying process. Haven't watered in 3 days now. They're not wilting. But they're not looking great. Alot of yellowing going on..

You can salvage them. It will be time consuming. You will learn stuff doing it... BUT you should start a batch of new sprouts too.

Also, cutting & rooting clones is *way* quicker, and your first plants, for each strain you have, should be a "mama" to cut clones from.

It takes a seed about 30 days of growth to get to the point a rooted cutting is at after only 3-12 days - It generally takes about 7 days on average to root cuttings.

Gove your seedlings more time indoors to get established… say 1 gal pot. Once you need to water daily then move the pots outside into a shaded area and moving them into more sunlight exposure over a week then plant them.

Plants going from indoor to outdoor suffer a shock from UV and then you add transplant shock and temp swings they have a right to get pissy.

Let em get a bit bigger before you so this again and harden them off before you plant them in the ground
