Hello! I'm growing my first non-auto, a SkittleZ, it got quite small and the leaves are yellowish,I'd like to know what mistakes I made and what I can do to help her Mars Hydro TS1000 and only BioBizz nutrients. Temp is around 18C at night and 25/26C during the day, 40% hum

Supercrop that tall cola. Done right you will be happy with the yield. The yellow one FLUSH FLUSH FLUSH and get your soil right. By right I mean after flush wait a day. Next determine where your NPK is if you want you don't have to. Dose according to mfg recommendations (less potassium if growth, minimum dose in flower), add PH up or down whatever your water requires. Drench the pot again with the mix, add a little magnesium if you want. Let it go a day then water as you would until feed day. Resume feeding if following a schedule. If you're dabbling with your fertilizer (mixing your own) you might want to rethink it. The others are just starting and correct able. No help opinion. If calmag is in the picture one or the other could block uptake. Check mag it's just under NPK in importance.

The way the serrated edges are raised and the yellowing is mostly on the top or where the light hits. i have to say that this is a case of light burn. its very minimal but i would raise or turn down your light a

The most important info you could give is the medium type.... I doubt this is soil so I'm going off coco probably and if so your not getting run off so salts have built up.. fire some water threw her and then on the next water add a little bit of everything you have that go together and I mean a little bit, just so it's there for her to pick and choose between. Make sure ph is correct.. 5.8-6 for coco 6.2- 6.4 soil.... She looks sad is that humidity, temp or to much or not enough light. I'd go to much light and humidity, do you have a fan breezing over her???. There a lot to keep in check..

If it was nitrogen it would cannibalize old growth so that new growth would look pristine. Nitrogen is mobile. Greening all over with no obvious starting point hints toward micronutrients. Temps are in line, rh in line, ... Slight burning of tips indicating possible high salinity in soil. In general, all micronutrients decrease in availability as pH increases, if I had to guess I'd say high pH is causing uptake problems, check ph, might also need to flush a little salt out of that medium. Feeding fert a little too fast for the plant over time possibly. Track EC to prevent.

Might want more of something or may need a bit more runoff in the feeds. Temps and RH seem on point. Start a dairy for next time. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg a leaf chart for refrence points.

HI bud. Without a diary it's hard to tell for 100% certainty. It looks as though she wants a little more Nitrogen (BioGrow) and perhaps a little more CalMag. These are nutrients she will need throughout the bloom period too. If those are already at decent levels, then it may be a ph problem. Do you measure regularly?
