Nice post bro, i am growing her in a rock wool cube filled with Hyponex Potting Soil i think what might be happening is the roots might be having trouble penetrating the rockwool but im no expert so i have no idea.
SOIL:
How long has this problem been going on? about 24 hours
What STRAIN are you growing? unknown bagseed
What was the establishing technique? (seed or clone?) seed
What is the age of your plants? 1 week 3 days
How long have they been in the soil mixture they are in now? since germination was done.
How Tall are the plants? 2 inches
What PHASE (seedling, vegetative or flower) are the plants in? seedling
What Technique are you using? (SOG, SCROG etc) single plant
What size pots are you using? (Include how many subjects to pot) right now she is just in the rockwool cube i was going to plant it once the roots began to show.
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) Im not too sure the bag does not list anything I had asked the lady for something without nutrients like a basic potting soil and she pointed me to this.
What Nutrient's are you using? none for now using only distilled water.
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
How often are you feeding? water her once the rockwool cube is weightless and soil looks dry.
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used?
What is the pH of the "RUN-OFF"? not sure how to check this.
What method of pH test was administered? Using Strips? pH pen? Electronic soil tester
How often are you watering? its coming out to about every 2 days maybe 2 and a half cause the CFLs dry up the cube pretty fast.
When was your last feeding and how often are you feeding? never
What size bulb are you using? 4 26w Daylight CFLs
What is the distance to the canopy? My veg box is about 2 feet tall i have the seedling about 3 inches from the lights.
What is your RH Factor? (Relative Humidity)35-45%
What is the canopy temperature? 78%
What is the Day/Night Temp? (Include fluctuation range) Ranges anywhere from 69-85 degrees at the coldest and warmest. 22 hour light period usualy an avarage of 75F
What is the current Air Flow? (cfm etc.) There is one pretty strong intake fan and a weaker exhaust airflow is good.
Tell us about your ventilation, intake exhaust and when its running and not running ? My intake fan shuts off with the light everyday for 2 hours and the exhaust fan stays on 24 hours.
Is the fan blowing directly at plants? No i heard that causes stress they are blowing at the pot i have the cube sitting on without shaking the seedling much at all.
Is the grow substrate constantly wet or moist? only for maybe a couples of hours after watering but they dry up pretty soon.
Is your water HARD or SOFT? how do i tell this? i dont know what the question is asking, i use Distilled water only that i buy at walmart in gallon jugs.
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Distilled.
Are you using water from a water softener? ? lol? again i dont understand what thats asking.
Has plant been recently pruned, cloned or pinched? no
Have any pest chemicals been used? If so what and when? no.
Are plant's infected with pest's? no.
So that about how my grow is working, im always open to pointers guys like i said im pretty new to this. Her leaves are still wilted the seed leaves or rond leaves whatever you want to call them the non true leave have turned yellow and on has blackend at the tip. Her stem also feels almost a little crunchy twig like. The true leaves are really wavy instead of being nice and smooth like before that came after the wilting and the yellowing, but about the same time i noticed her black tip.
