First time grower, long time user!!

Short and dense plants are good. They show strong, healthy growth. You don’t need to raise your light to make them taller. Keep the light at its current height if plants look healthy. Watch for stress signs. Leaves curling up or bleaching mean the light is too close. Yellowing on the second plant could be pH issues or nutrient deficiency. Check water pH: 6.0–6.5 for soil. Let the soil dry a bit between waterings. Yellow lower leaves usually mean nitrogen deficiency. Yellow between veins usually means magnesium deficiency.

That yellow is called variegation.. it's harmless and not related to anything you caused. The plant is healthy. Controlling the climate is value-added, too. Beyond that, there's not much you control. Keep it happy and it'll approach its genetic potential. that's the ceiling, regardless. Can't put lipstick on a pig, when you get one. they happen. (not saying that's the case here.. far too early for any assessment) is node spacing still healthy? Node spacing of new growth can help determine if providing too much light. Too tight and it needs less. Too stretched and it needs more. Keep an aye on that and you'll figure it out. Once you find a good light distance and power, yes of course raise the light to match the growth. From what i can see, it looks fine as is.. maintain... unless you see new grwoth is too tight. Local variables make what you do with your light a bit different than the needs of another garden. So you always have to use the plant's growth pattern for local adjustments. about light - not typing it again when you can just swap out numbers to recalculate... it's explained fairly well here -- growdiaries.com/grower/bunnybud

They look really good, I can't see that you're doing anything wrong 😉

I AGREE DA PLNATS LOOK FINE!!!

They looking great don‘t worry… the Most height gain is in flowering Stage 1-3 weeks into flowering ) about 100% of their current hight, you wan‘t bigger plants ? Just let them veg further but remember that the Most hight gain will occure in flowering it at least the Most rapid hight gain

Hi mate, don’t worry — your plants are looking really good, especially for a first run 👍 I can’t quite tell the exact distance to your light or the wattage, but they should gain some height during the stretch anyway. If anything, you could slightly adjust the light (distance or power), but honestly it looks like you’re on the right track already. That could help, but it’s not a must.

Hey. For a first grow, your plants at day 24 really look great, you don’t have to worry! Here’s what I think about your questions: 1. Height and density: Raise the light? Your plants are indeed very short and dense, which shows they’re getting a solid light intensity. My advice: If you plan to do some training (LST) to open up the plant, they might be a bit too compact to easily manipulate the branches. In that case, raise your light by 5 to 10 cm. This will encourage them to "search" for the light and stretch a bit, giving you more space between the nodes to work with. If you don’t plan on doing any specific training, leave them as they are: a stout plant is often more robust. 2. The yellow spot (Plant #2) I took a good look at the photo of your second plant. The yellow mark is very clear and localized on a specific part of a leaf. To me, this isn’t a pH issue. A bad pH would cause more diffuse yellowing, often on the edges of the leaves or on new growth in a generalized way. What you’re seeing looks a lot like variegation (a harmless little genetic mutation where part of the leaf doesn’t produce chlorophyll) or a small localized stress. Nothing serious, the plant will continue to grow normally. 3. pH check-up Even though the yellow spot doesn’t seem related to pH, it’s always a good habit to check it for your "Photos" (photoperiods). Make sure you’re between 6.0 and 6.5 if you’re in soil to ensure that all nutrients are well absorbed in the long term. In summary: Don’t change anything drastically. Just raise the light a bit if you want them to "breathe" a little more in height to facilitate your future training. I also have two little ones in size, my cola cherries, which I invite you to come see. Sometimes size doesn’t mean anything. There are phenotypes that stay small. I hope I could help you. Have a great day!
