Otherwise known as over watering.

should be called what it is Grower/// operator era ,,as if they had done the first job well,,,and provided a soil that booth feeds and provides drainage as in nature,,, would be no need for the term ,,over watering,,is it is a human era and has little to do with the plant and more to do with drainage of medium mixture which is human era,,,other wise all hydroponic grows would fail as those roots stay wet difference is there not in a heavy wet soil being suffocated,,roots can handle water just fine,,,seen trees with them hung down in running creeks all my life

I should be cool then. I'm growing in a coco perlite mix, it gets plenty of air and water passes through fine. I'll have to use nutes at some point or another though since I don't have them already mixed in the soil. I'll just probably wait a lot longer.

The little round leaves the "cotyledon leaves" are the food source for a seedling, a seedling only needs water till the cotyledon leaves start to yellow.

(A cotyledon is a significant part of the embryo within the seed of a plant. Upon germination, the cotyledon usually becomes the embryonic first leaves of a seedling.)

That is amazing information I hadn't heard yet, thank you for sharing that!

But, it exists. And, it happens.

Shut up pinworm...we don't want to hear any more of this over watering nonsense...plants grow hydroponically all the time so there can be no such thing :-|

Over watering is one of the more common causes of plant problem. Heavy and poorly drained soils are susceptible to becoming waterlogged. Roots growing in waterlogged soil may die because they cannot absorb the oxygen needed to function normally. The longer the air is cut off, the greater the root damage. The dying roots decay and cannot supply the plants with nutrients and water. Damage caused by over watering is frequently misdiagnosed as pest damage. However, pest damage rarely causes roots to concentrate near the surface of the soil. Plants stressed or injured by waterlogging can become abnormally susceptible to certain fungal pathogens. Phytophthora spp. for example, cause root rot most often in soils that are periodically waterlogged.

Symptoms and Diagnosis

Plants growing in soil that is too wet suffer from a lack of oxygen which leads to the death of roots and a loss of vigor in the plant. Stunted slow growth with yellowing leaves is a symptom of over watering. Plants may suffer from leaf scorch or leaf burn. Water soaked spots and blisters (Oedema) may appear on stems and leaves. The crown of the plant may rot. Damaged roots have little defense against the entrance of rot causing soil organisms. And so the plant dies of root rot.

Oh trust me, I know it exists. There is no denying it. You can see the way the plants visibly react, even without researching WHY that happens. What I'm having trouble with is figuring out where that fine line is with this coco perlite mix. I'll stick my finger an entire inch down and it feels bone dry sometimes. Hell, look at the pictures I attached, those cups were watered only the day before, but it looks like a barren wasteland on top haha. What I'm getting at is that the coco is never quite "waterlogged", but the plants can still be overwatered. It's hard to figure out imo.

Edit: What I have been doing is taking a cup filled with dry mix and weighing against the ones with plants to get a feel for how much water is left. Obviously not a perfect method though

way to young to feed give them two three more weeks. i would only feed with something with low numbers 1-1-1 or lower and maybe some ag minerals for micro nutes. take the one you feed as a leason learnd water as normle and hope it makes it

One of the easiest ways to prevent over watering in small cups like that is ...make sure you have drainage holes.Put down a small saucer with a small amount of water and let the medium absorb it.

It forces the roots to hunt for water....this is a good thing...aggressively rooting plants are healthy plants.

Try weighing the container after watering, then wait 2 days and weigh again.
Note difference, does the plant look thirsty?
still seem well watered, wait a 3 rd day.

The larger a plant the larger the root system the more root surface area to absorb water and nutrients, the more often a plant will need to be watered.
Also as the root system fills your container there is less room for water.
So the resevoir of water being retained by the medium needs to be filled more often.

Here IS A Watering schedule to consider.

(F feed nutes)
(W water only)
(N nothing)

FNNNWNNNWNNNF at 1/4 strength what any nutrient calls for.

In my hempy grows in flower from day 1 my schedule is
FNNNWNNNWNNNF

After 4 weeks I change to FNNWNNWNNF for my last 4 weeks, if the plant looks dry during the last 2 weeks I change to FNWNWNF

Environment is very important,

Lights on 12 hours 18 or 24.

I use 24 hours for seedlings and clones.

I switch to 12/12 for young plants as I only veg a week and then it goes in my SOG.

I use 80/80 as a standard.

80 degrees and 80 % humidity

clones for 7-10 days,

for seedlings 14 days,

for young plants 7 days.

DZ

A rigid schedule is a bad idea imo...once a plant has established roots.Evaporation rates,plant utilization rates etc will all change throughout the grow...feeling the weight of the pot is a much better system than some ridgid schedule imo.

GreatwhiteNorth · Apr 17, 2016

Yep, schedules will fuck you.
Just check the moisture levels in the soil - you can tell just by grabbing a handful of soil - dig down a bit, after you've been in the game for a while it's not that tough.
Also, watch the lower leaves - when really dry they will begin to droop first.

To flush, or not to flush?
