I am having a couple problems my first time grow. I had 3 plants given to me 6 weeks ago. They were 2.5 feet tall not sure of the breed I was told mayzar. Firest plant has been in bloom cycly now 5 weeks looked real good with the exception of some burning at top so I moved lights up to 20 in away. Trimmed some of the burnt leaf tips and lower leaves that were dried out. Now many of the older leaves are browning and curling but the new growth on stalk and buds looking good.

Now I added other 2 plants into flower room a week ago. Just before I added them to room I sprayed with some organic pest spray because I had a mold fly issue from soil decay. The spray was all natural mostly cinnamon oil and some did get on the 2 plants just added wich created some golden spots on some leaves. Have not seen any flies in flower room but some still in veg room. I am afraid I am over watering or under watering. Each plant gets 3 cups of water once a day and the water has sensi bloom phase 2 nurti.

What is your experience level? (first timer)

Your Equipment:

.2) Distance from tops? 18-24 inches
.3) Reflector type? (bat wing,
.4) Is there a consistent fresh air supply? y
.5) Do you have an exhaust fan and a circulation fan? y
.6) What are the bulb wattages, kelvin ratings, and schedule? 400w 12 on 12 off

Your medium:
.7) Specific brand and type of soil, not sure
.8) Size of container. 3 gal
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? Seeds

Your nutrients and water:
10) Source of water? (tap let stand 48 hours then add sensi bloom phase 2 per bottle measurement 3T per galon) What's it's ph before adjusting? have not checked ph
11) Method of checking water ph. (none)
12) Method of adjusting water ph. (none.)
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. none
14) How often are you watering between feedings, and how much per watering? water once a day 3cups
15) Any additives or tea's? (sensi bloom 2...)
16) Are your ph levels stable, or do they fluctuate?
17) What is your ingoing water's ph? ...your runoff ph?
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? not sure I do spray leaves once a day as this is an arid climate

Your growroom:
19) Indoors
20) What size of room 5x6 feet
21) What are the temps and humidity levels while lights are on? ...With lights off? temp 80 no humidity
22) Have you seen signs of insects in the growroom? yes mold black flies

You have much learning to do my friend..... Spend any free time you have in the FAQ section.... Get yourself a good ph meter - lookup "ph600".... Get yourself a hygrometer.... PPM meter is recommended but optional....

Their is no such thing as "no humidity"..... Black mold flies come about because of a moist environment....

Anyway, you would be better off giving them a liter or two of water and letting them sip on that until the soil almost dries. This will keep unwanted pests out of your soil. You can judge the moisture in your pots by simply picking them up right after watering then each day after. You might also be over feeding. If you are foliar spraying them past the fourth week of 12/12, stop. You don't want an increase in exterior moisture on your buds, could cause mold to grow on them....

For now, you should flush them really well, if you haven't already.... And read, read, read......

Hope this helps....

I take it you're not foliar feeding, but just spraying with water, since you say it's an arid climate, is that right? Don't bother spraying anything, water won't help much if it's on leaves unless you're not giving enough water through the soil and it looks like you might be okay there. I don't know if giving fert every time you water is a good idea. cangroit is right about how much water to give. Don't try to over-control the plants. Let the soil dry out such that you and put some of your index finger in the soil and it feels pretty dry, then water. It you have a dry climate and it's warm in the grow room, you might have to water pretty often all the same. Perhaps that's why you water so much already. If you have mold in there that has attracted flies, try to get rid of it. It's not good for you either. Flies are drawn to the chemical odor of decomposing organic material, like dead bodies. You can find a dead mouse or bird inside and that will be enough to attract flies too. It's hard to tell what your plants look like under sodium light. Try to take photos in white light with a few closeups.
