Hey everyone,
I need some help. This is my second grow. Last year I used poor quality soil and needed to feed them a lot. This year I used Fox Farms soil and it seems to be running hot with nitrogen, but I'm a newbie, so it could be many things. Here are the details of my grow...
- Fox Farms soil, in 5 gallon pots
-Grown outdoors, (but I bring them in at dusk and keep them under flourescents on a timer so they get a full 18 hours of light and don't flower early.) I had this problem last year, and a few of my plants flowered early this year too.
-They haven't been fed any nutrients yet.
- I use PH down to bring the tap water down to 6.5-7.0 when I water.
-It gets hot where I live (Northern California, near Sacramento) 90-100 degrees
-I am growing several different strains, all bagseed, none are from seed banks. One is from Humboldt, one is Afghani, and the other are Northern California Hybrids. The Nor Cal hybrids seem to be the most sensitive. The Humboldts seem to be the strongest.
-They are 9 weeks old and average height of 2-3 feet.
Hopefully some of you can help. I can't afford to buy MJ and I depend on it medicinally, so this grow is very important to me.
Here's my problem. It looks like I have nutrient burn, but from all the reading I've done, it could be a nutrient deficiency. I don't want to compound the problem and make it worse by doing something wrong. I have heard a few people say that the Fox Farms soil runs hot with nitrogen, so my thinking is that it is nitrogen burn. The plants grow vigorously and are very green, and then suddenly develop spotting on the fan leaves on the middle of the plant. Since it looks like nutrient burn, I flush them, and it seems to help, but it just happens again in a few weeks. Is the soil too rich in nitrogen? I asked some of the local growers and they said to just keep a close eye for the spotting, and as soon as I see it, flush the soil.
Do you agree with this? Or do you have another possibility? It seems like I have to just keep watching the babies and when they get spotty, flush them, but I am also flushing away nutrients that they need, which makes me think I'm causing nutrient defiencies at the same time.
Also, it seems like the nutrient burn happens when the outside temperatures get above 85 or 90 degrees. I built a shade cover with some shade cloth, and hopefully this will help on the extreme hot days.
Does Nitrogen get more active in the plant when the temperature raises above 80-85?
The spotting turns to yellowing, which turns to crisping of that area of the leaf.
Also, you can see in one of the photos the leaves are folding up like a taco, what could be causing this?
