Thanks for picking Super Lemon Haze! Good Luck.

I agree with @Shmok2004, and @Philindicus, decrease your light distance. With my LED lights (324 real watts) I shoot for 15-20" to control stretch. I would pull the humidifier out of the center if it's blocking the light to any of the cups. I find it works better for me to locate the humidifier in my setup just outside of the grow area, and let the fans pull the humidity into the room. But they look like they are on pace in soil to me.

I agree they are stunted. It looks like they need more nutrients because the lower leaves are turning yellow.I'm going to say nitrogen and maybe phosporus right now.. What kind of fertilize and how much/often are you using it? They are definately starting to bloom you will problably wind up with one small main cola with a few smaller buds around the lower areas but don't write them off. I've seen some crazy red solocup weed grows with some really nice buds. Also are you using a ph meter? What is your water ph your putting into her pots? Even though they are in bigger pots the roots will never grow to fill the pot so you still need to watch how much you are watering them what will happen is the top of the pot will dry out but the bottom will stay wet/ moist. If your trying to keep things simple some folks are using one part feeds like maxibloom Megacrop etc. Along with recharge for beneficial microbes.They seem to have good luck using this regime.

@Saber, yes looks like you starting to flower. Really we could use a bit more information on what your feeding to make better calls. @philindicus has hit the major points, you'll do better checking the Ph and TDS of your water, then adding nutes to keep from over feeding, but right now it I would give a healthy dose of Micro + Bloom and a bit of Gro too. How much would be hard for me to say given the unknowns.

As they started flowering you should also give flowering nutrition from now on, at best you follow your feed chart for your nutes. Let´s hope they will stretch during flower.

Light is 2 Meters away ? May to much distance !

They spent too much time in those cups, which kept them small. Also your soil looks kind of poor.

The N-P-K on the fertilizer is not really ideal but it's better than nothing. I would cut back on the amount just use 1/3-1/2 strength. The amount of phosphorus is very high and could be locking out other nutrients like manganese, magnesium etc. When the plants are flowering they like a bit more calcium, magnesium and potassium. Natural sources are unsulfured molasses if you can find it where you are. 1 tablespoon per gallon of water.

Looks like you have a pest issue my friend - try using bacillus thuringiensis

Looking a little closer I think you may have spider mites.... I have no experience with these and it looks pretty infested tbh

Nice work!!

@Saber Hi there my friend I put an answer in for your grow question Hope it helps you 👍

Hey there, hope i answered your question, since you're already so far along there's not much else you can do just give them flower nutes and get those temperatures down if you can, anything else you need, just let me know 👊

@Saber, Yes you can use your bloom nutrients. What were you able to come up with for nutes? What is the N-P-K of the nutes? I see your still struggling with heat issues. I guess when it's over 100 F outside it's not helping you out much even running an air conditioner. I would suggest only running your lights on 18 hours a day and 6 hours off. Try changing the time on during the coolest part of the night and off during the hottest time of day. They will like having a bit of rest and this could allow them to cool down. It would be nice to have a 7 F to 10 F day night temperature drop your at 5 F which is bare minimal.Keep in mind that if you are using a HPS high pressure sodium bulb they put out more infrared light which will cause the leaf temperature to be 8- 10 degrees higher than the room temperature which can stress them out a lot.It is very possible the leaf temperature is close to 90 F. The reason you want lower temperatures and proper humidity levels is it will cause the leaves to open their stoma located under the leaves when the lights are on. The stoma take in Co2 to create photosynthesis activity. If leaf temperatures are too high and the humidity too low the stoma will close which will also slow down how much water and nutrients can be pulled through the roots. This translates into your having "Leaf Vapor Pressure Deficit" issues. At those temperatures you would need a very high humidity level which would be bad for the buds and cause mold issues. These heat issues will simply cause smaller loose looking buds and it can burn off terpenes effecting the smell, taste and potency of the bud. You have some very difficult growing conditions to deal with. Some tropical/desert growers take a break and grow during the cooler seasons to maximize their grows. Good luck I will continue checking in on you.

Forgot to say you can use a fresh water ph test kit from a pet store that sells tropical fish. It should use a ph range of 6.0 to 7.6 typically. Test your tap water first you would like the ph to be between 6.0 to 6.5 for soil grows if it is too high you can use a few drops of white vinegar or lemon juice (acidic) to lower it. To raise it you can use Sodium bicarbonate but use it sparingly excess sodium is not good for plants. Also if your water has chlorine in it leave it out in a bucket overnight stirring it several times for the chlorine to gas off.

The one plant that's really yellow looks like the leaves are drooping down a bit it is a sign of over watering. The root system is still very small for the size of the pot. More than likely the lower and middle of the pot is still wet when the top starts to dry out. If you lift the pot you can get an idea of how heavy or light it is to help give you an idea when to water. Let them dry out a bit more than usual then stick your finger into the soil up to your first knuckle to see if it is dry. Using both of these ways to gauge when to water. If the soil is too wet the roots can't pull in nutrients properly. Everyone is guilty of over watering at some point or another.

Yes at least use a fan a light breeze will help, an air conditioner would be better. Since they are in veg still you can also use a cool mist humidifier to increase your humidity it may help them out a bit don't let it blow on your light/bulb. The leaf temperature is the real issue if your at 86 F the leaf temperature is even higher. Put a thermometer at about the height of the top leaves. Heat could stress them out and cause them to be stunted. Looks like if your going to try to put them in larger pots this would be a good time.

Ah, just found the new pictures. watch the heat. 31 C is to much . They feel fine between 22 C and 26 C. This is what i have seen.

With heavy soil it's easy to over water you can try to add 25-30% perlite to your soil mix to allow it to drain better when you re-pot them

They look good. You just need to be careful when growing auto flower that you don't stunt them by leaving them in a small container for too long. Most growers start autos in their final pot size. I would consider moving them into larger pots soon. For smaller autos 2 - 3 gallon pots are usually large enough for XL -XXL varieties 5 gallons would be more suitable.
