First Indoor Grow

while it's nice to have a 0-100 dimmer, at some point you do lose integrity of spectrum produced. get a smaller light for early stages -- save even more money and maintain advertised spectrum tailored for photosynthesis. or, stick to 50% + and raise light to 24 inches, may need to watch and react to dial it in. i used the fc4800 at 24-36" and 66 % -- slowly lower as the seedlings mature... your vege power will be oughly 66% over 18 hours vs 1hours for bloom... easy adjustment at flip.. simply bump light to 100% and maintain same height. looks like you grow autoflowers, so you can increase height and increase coverage area and use at 100%. hours of use is a relative factor -- adjust 1:1 in aproportional way if all other factors remain the same, like distance from canopy. figure 50-60umol/s per sq foot will do you well.. use spec sheet to guesstimate area of coverage for 18hours/day using this info. adjust height of light to best cover this area (a cheap lux meter helps measure various locations to even it out)... 3'x4' might be doable. any smaller area will require some dimming at that height. distance from canopy is an option to adjust such things, but it's better to use height to adjust area of coverage / even out coverage as best you can. a few inches either way is no problem, of course. only if it causes me to over-dim will i consider changing height. Seedlings are definitely one of those situations. so this is more for when things are rolling. with seedlings don't be too put off by what i said about spectrum integrity... i use a xs1500 at 10-25% on viyyomhd all the time, but with seedlings i don't need to drop below 50% at a decent height for coverage. when you use a large light for small plants, it's a little sub-optimal. err on the side of slightly weak light and adjust to stretching quicly as needed. it's easy to stunt seedlings with a big light. can always 'fix' a slightly stretched seedling with xplant depth vs a stunted one that just takes time. if it ever grows out of it.

Zu viel Wasser und Licht ✌️

Yeah, they're pretty small but don't give up! I would move your light up higher... 24" from the plants would be good... and give them 100% of the light (autos, once they've been "hardened off" to light, will take a lot of it without harmful effects. They also need a lot of humidity around them at this stage - it's pretty much the only way they get water since the root system hasn't really gotten off the ground. I like to wrap a wet towel around them in a circle so the ambient humidity is very high ... After a week or so of that, and when they get another set of leaves on them, you can let them fend for themselves in the humidity the entire tent gets... which should be around 60-65%. Don't start feeding them for at least another week but when you DO start feeding them, introduce the nutes slowly - i.e., at about 1/4 strength to start off. The biggest piece of advice I would have for you is to introduce some microbes into the soil... these will help grow the root structure... once a week feeding of microbes is all it will take (don't give it to them more often than that at any stage of growth). I think you'll start to see these little ones take off pretty soon and I wouldn't worry too much... make sure your water is pH'd properly, add some microbes, pull your lights up a bit, relax and enjoy the journey!

With photoperiods, you want to wait until they have at least 4 nodes... with autos, wait until there's an issue you want to resolve be it spreading the plant out to get more width or getting more light into the middle of the plant. You don't HAVE the do any LST but it does help give bigger yields. Sometimes, just tucking the large fan leaves down and under is all the LST required. I wouldn't worry at all about what you've done with her... it's a weed, after all, and they'll do fine! There's something to be learned with EVERY. SINGLE. GROW. you do... As I always try to tell folks, relax and enjoy the journey!

Without a picture or two of the issue, it is very hard to provide any suggestions. However, burned tips is usually a sign of feeding too much or too often, or both, and after looking at your diary, you sure are feeding a lot of different nutrients. A baby plant needs baby feeding! Also, 24/0 is really stressful for plants and 18/6 is the optimum schedule. Plants NEED sleep to finish their photosynthesis cycle and have a correctly functioning metabolism. A plant with an incorrectly functioning metabolism will never grow to its best potential. 24/0 could only be recommended by people who don't understand photosynthesis or understand how plants function either. The myth that it is ok to grow a plant for weeks/months without sleep needs to be removed from history! Everything on planet earth lives by a circadian rhythm, without one things go very wrong. Fortunately, it is never too late to go to 18/6! Your plants will love you once you give them the sleep that they NEED. Hope this helps, Organoman.

Recommended is between 5.5 and 6.5 sweet spot being between 5.8 and 6.3 I recomend checking your ph runoff regularly to make sure your coco is in range.

Hi there. Try and vary ph between 5.8 and 6.3 for coco. I don't use your brand of nutrients but I do grow autoflowers. You are probably running a high Ec. With autos you tend to find they don't like to strong a solution. EC about 1.2 to 1.4 is usually where they like it, some a little more some a little less. Invest in a Ec pen and check your levels.
