I use fox farms ocean soil when should I start 1/4 strength nutes.
Yep I'm pretty sure the soil sucked I got it at lowes leftover from summer. I'm going to my local grow shop to get fox farms.
The initial symptoms are the yellowing of the entire leaf including veins usually starting with the younger leaves. Leaf tips may yellow and curl downward. Sulfur deficiencies are light green fruit or younger leaves with a lack of succulence. Elongated roots and woody stem. Although it's hard to see in figure 19, the upper stems of this plant are purple. Although many varieties of cannabis do get purplish stems, the trait generally extends the entire length of the plant's stem, and not just near the top as in this specimen.
Mix 1-2 teaspoons of Epsom salts per gallon of water until condition improves.
when the hole leaf turns yellow slowly i would try to rule out something like a sulfer deficency, by adding a little bit more nitrogen
ggrant, I will follow your advice. I'm a man of action and I am not to proud to follow the advice of more experienced growers. I was planing on getting some cal mag, can i do both epsom salts and cal mag?
Look closely below, and you'll see the brown leaf edges that are indicative of heat stress. This damage looks alot like nutrient burn, except it occurs only at the tops of the plants closest to the lamps. There's only one cure for this...get the heat away from the plants, either by moving the lamps or moving the plants.
Hey Rupe,
You can use both. As I mentioned, some growers use Epsom salts with every watering, even with nutrients. The Epsom salts is way more imporant at his stage than CalMag, but use both if you like. CalMag had calcium and magnesium, but no sulphates. A little extra magesium is fine. Magnesium toxicity is very rare and definitely not going to be a problem here.
Use the Epsom salts right away, and if you're so inclined, make a foliar spray with Epsom Salts in it. Use the same concentration as for watering. (1 tsp / gal). You'll get faster results if you foliar spray. (You can do both - water and spray with Epsom salts.)
The edges of the leaves look burnt. Miwa said they may be too close to the light. You're using HID MH lighting, is that right? Is so, move the sick gal further away from the light.
Heat Stress:
Ok bro if you want to throw salts in there totaly up to you. But in my expirence if i would add more of something things to try to compinsate for something i thought it was lacking it just got worse. If you flush your starting back at ground zero. So you know you can start your feeding lightly then build back up to a tolorable level. So what happens if you throw the salts in there. witch lockout is a layer of salts that coats the roots so the plant cant absorbe what it needs, to add more salts then.... Na im just kiding about the death part but really bro go ahead and add your salt i am interested to see the results. If your feeding your plants correctly you shouldnt need to add salts. I personaly have never needed to use salts but im sure thousands of people on this site use it. so you can also take this with a grain of salt lolz
