It seems quite small for 20 days in. The last 10 days, it's been growing, but not much. Is my Ph too high and temperature too low?
Week 3

Ph at 7 is too high. Aim for 6.2 in veg in coco coir and 6.5 in flower. She looks like she has a nitrogen deficiency starting and that'll be a ph lockout. Day air temp could creep up a bit to 80f or a little higher if you have good air movement (night is fine). Humidity at 41% is very low so think about trying to up that with wet towels / humidifier. What you have not told us is substrate temp or solution temp. These need to be 72-74 as lower will cool the roots and slow growth. Just a few tweaks and she'll be fine.

hi-i would try to get temps to 26c
ph must be not more than 6.2
i noticed a heating radiator in your facility - your humidity is 40% due to the radiator that is drying the air.seedling need high humidity at least 60%.
try to raise it.
i would not use any nutes right now until growth is more vigor.
dont worry about growth rate-you would suddenly get a boost if you apply all ideal environmental conditions

Hi there! Indeed, she looks small, but she also looks very wet! I think over-watering + basic pH (too high) led to this situation, the plant cannot absorb any nutrients. In coco, it's all about the feeding schedule, since the substrate does not contain anything, the growth relies on your ability to feed correctly. Now as an emergency move, I'd try to give her a good meal (when the coco is dry) with RootJuice+BioGrow, pH 6.2, and see how she reacts. You may want to stop spraying anything onto her, let the roots search for water and nutrients, spraying is good for nutrients lockout or extreme dryness, in your scenario it's not helping. I'll be around, keep us up-to-date so we can help you adjusting your parameters, and happy growing!

What soil are you using? If not strong good soil, then nutrients are necessary. 7 is a little higher for soil which is ideal between 6.3-6.8. Temp looks good. The soil looks a little dry or is just me? You could use a cup or bottle over the top to up humidity and temps. Those little guys like warm and moist all the way. She may just need time too, some strains take longer than others....but being patient is a Bword.

Your temperature is near perfect and is not an issue at all in regards to your plants growth. Your ph however is definatly a bit high as GL420grower has stated. However I disagree with what he believes to be the optimum tang for ph in coco. It should be between 6.2-6.5. The reason for this is because coco coir lacks in nutrients especially Calcium. Calcium is very important in your plants growth and stem system. Calcium is most effectively absorbed into the root system between the ph of 6.2-7. The reason I suggest 6.2-6.5 is because this is the ideal and optimum range for most all nutrients to be absorbed through the roots. As far as your plants height and overall size this is fine. It may just need a little more time developing its roots in such a large pot. What is most important is that the leaves and overall heath of the plant looks good! Good luck on your grow and have a good harvest!

Your temps shouldn't be causing you any issues but your ph is deffinatly too high you want it to be around 5.8-6.0 in coco.. it might be worth testing your runoff though because your ph being out will cause nutrient lockout

if ph is 7-8 then yes it's too high buddy u need to be around 6 temp is fine you could spray the walls to raise humidity
