Hey guys im a first timer in need of a little direction. I have a 5 week old northern lights baby and shes started yellowing lightly on the bottom fan leaves. Its in a small tent with a 150 watt cfl, lots of circulation. The temp ranges from 75 to 82 dregrees f. Ph levels are aroun 6.5 to 7. I have been using miracle grow 18 18 21. In very low doses about every other feeding. I attached a few pics!! Plz help!
Needs more nitrogen. You soil doesn't look so good. How about some foxfarm perhaps?
Hey pollishpollack, I picked up dyna grow 7 9 5 today. I'm waiting till tomorrow to feed though. I saw you suggested that for a nitrogen deficiency in another thread. Think that would do the trick? Also thinking about a transplant to better soil.
Yes, those are both very good ideas. Dynagrow fert is especially good as it contains most of the nutrients for plant growth. The problem with this fert is it does not have a long shelf life because the calcium and phosphorus have a chemical attraction for each other. They bind together and drop to the bottom of the container, rendering each other useless. But when the product is new to you, it's good to use. Just don't expect it to be good 6 months from now because that won't happen. When using this fert, as with all ferts, follow the directions on the back. For a soil grow you use 1/4 to 1/2 teaspoon in a gallon of water. Since you're showing some deficiency, I'd say use 1/2 tsp. Don't water with this mix every day; let the soil dry out some before you water again. Feeding more than a plant needs might result over nute burn. It's easier to give more later if necessary than to wash out excess fert. So just feed once and your plant should perk up in a day or so. Transplanting to a soil like those sold in a grow shop is a good idea, but you can also use soils sold at hardware store. The difference is that the manufaturers of the grow store soil understand what plant you're growing and have made their soils to accommodate your needs. If you transplant, I'd suggest that the smallest container you use is a 5 gallon bucket. A bigger container is probably better, but a 5 gallon bucket will probably be enough space to accommodate the entire grow period provided you don't try to grow it too long. The dynagrow fert is also good for hydro if you want to try DWC but you have to use one teaspoon per gallon of water. Grow store soils may not require much of the dynagrow. They should be good on their own for a while, until you start to see some nute deficiency or the grow has gone on for a long time. About your avatar, where is that located?
Looks like the British Virgin Islands to me. :D
Weeze
Thanks for all the info. Very helpful. It is indeed the bvi's. My favorite place in the world
