Yellow Skunk Help!?

[Sizzlrod1]

I am having some severe yellowing of my lower fan leaves of my skunk plant. I am about 28 days into flowering and the problems came on quick about 2 days ago. About four days ago I let them get a little dry and the leaves were starting to droop, so i am not sure if that is the cause because before these yellowing leaves my plants were healthy and green.

First of all I want to thank sproutco for your help on straightenig out my fert deficiencies and all your previous advice. Here is what I have been feeding them for flowering MG 15-30-15 at a quarter strength, also a 1/4 tsp each of gardening gypsum and epsom salts per gallon of water. Also, when i repotted to the 10 inch pot I added some dolomite lime to the soil. The fert also has the required micro nutes of boron, copper, iron, Manganese, molybendum, and Zinc. I looked in vain for other suitable nutrients but I needed some and the MG was all i could find locally. I looked for Jacks and Peters. I have also been unable to locate ph strips in the range I need 4-7, I PH may be the factor. Nitrogen? Any help would be apprecited, check out the photos below......

> Stop adding the gypsum and epsom everytime if there is dolomite lime in the soil. Add the epsom gyspum now only every third fert or so.

> You can get ph test strips in proper range from a make your own wine/beer store. They should only be a couple dollars.

> Use 1/2 to 3/4 teaspoon mg everytime you water. (about 90-135 ppm nitrogen) Be sure to adjust fert water ph to about 6 after mixing.

Tip: You might find it beneficial to use potassium nitrate (13-0-44) every fourth fert instead of mg. This is the ingredient in some stump removers at hardware stores. Dexol and greenlight are two brands but there are others. Check the label. You would use 1/2 teaspoon per gallon KNO3 instead of your regular ferts. This would be 95 ppm nitrogen and 270 ppm potassium. This would be a break from applying some much ammonia/urea nitrogen and be nitrate nitrogen instead. Avoid toxicity. It also would be a break from applying so much phosphorus. 15-30-15 contains quite a bit. This builds up in the soil and does not leach out much. KNO3 would also boost potassium levels the mg really lacks.

Thanks for the help!!

Thanks for the help!!

Sproutco, thanks for the advice, I fed her 1/2 tsp per gallon last night with distilled h20. I will be looking for the potassium nitrate and the ph strips this weekend. This is my first grow so i have probably made some mistakes but I will be much better prepared next time around. I plan on using a soiless mix along with maybe the floranova gro and bloom, I read your thread on both of these. Do you think it would be a good idea to reveg this female after harvest and then take cuttings from the new growth and root those? I started with 3 blue mystic and 1 skunk, all the BM's turned out to be males and the skunk was the only female out of the group. Also, the Skunk seeds were Gypsy Nirvana freebies, I believed they were Sam the Skunkman Skunk #1's. Do you happen to know the flowering times for these and also maybe the ratio of Sativa/Indica. Thanks for all the help!

Apply a one time high dose of 1 teaspoon epsom salts per gallon of water. Resume normal feeding plan.

nitrogen issue, need some nitrogen there ph may be a factor

How often are you using your nutrients and how much? are these plants in the same tub? more than one plant?

what soil mixture are you using?

that is a nitrogen deficiency you have, why? need more information to find out

Sproutco and Friends, I fed my skunk 1/2 tsp of Grant's stump remover whose ingredient is Potassium nitrate, KNO3. That was 2 days ago and leaves still are yellow and some are falling off. They are now 5 and 1/2 wks into flowering 12/12. Here are some pics from today.....













I have still not been able to find ph test strips but I did start using distilled water. This is my first grow and I don't want to lose these buds!! This is one plant in a 10 inch pot. The soil mix is scotts seedling mixed 4 to 1 with perlite with added dol lime. Should I flush or what? I have been adding 1/2 tps per gallon of MG with added epsom salt and gypsum. Next time I will definately use better food!! Thanks for the help!!

it seems like your buggin to me..

those plants look fine,

your not in any danger of loosing anything imho..

a little leaf yellowing happens from time to time... when the whole plant begins to turn yellow... thats when you should start to worry

peace, and goodluck to you..

I think its a touch of magnesium deficiency

Spray 1 1/2 teaspoons epsom salts per quart of water on both sides of the leaves. Spray till plants begin dripping. Next day, respray with only plain water but don't spray so much that the leaves begin dripping this time. Resume normal feeding with the epsom and gypsum every third time and maybe potassium nitrate every fourth feed. You should find ph test strips at a petstore in the aquarium section...I guess walmart would have them. Or, go to a brew your own beer wine store...they will have ph around 6 test strips. I bet your ph is high. You did good finding the stump remover. Hold on to it.

Sulphur (S) deficiency

But I also think that at your stage of bloom, its natural for the lower ones to take a hike...lol..

can we see some day 40 pictures.?

DON' SPRAY ANYTHING ON YOUR PLANTS ! THIS LATE IN FLOWER !!!!!!!!

It is normal for a plant to show nitrogen def @ 30 days in flower .
If you want to green them up then just hit them with a high nitrogen fert next feeding and they will green up for you . But if you are not loosing 5 plus leaves aday on the plant then i would just keep feeding your bloom nutes and give them a good flush at the end . If your lucky you will get the bud leaves to yellow at the end of flower making it a Nitrogen free plant at the end and you will love what it does for the taste of your smoke .

Magnesium drench rates per gallon of water

If you don't spray the mag, make sure a total of 2 teaspoons epsom is watered on the plant. If you have watered with 1 teaspoon already, next watering add 1 teaspoon. If you have only been adding 1/4 teaspoon at a time then use 2 teaspoons once. Then go back to regular feeding.

Thanks for all the input guys. I believe I need to feed today or tommorrow, should I do a regular feeding with 2 added teaspons of epson salts or just a watering of only epsom salts. I will continue with my bloom fertilizer, maybe a 3/4 tsp instead of 1/2 tsp. Also, I am now 38 days into flowering, How much longer can I expect to let these guys flower 55-60?? These are skunk #1 freebies from sam the skunk man. Should I be thinking about switching to h2o only for the last 2 weeks? Thanks, Sizzlrod

I think you will be ok with a spray of epsom at 1 1/2 teaspoons to 3 teaspoons per quart of water. Spray both sides of the leaves. You should get good results. Trust me. But if you want, you can add it to the soil instead at 2 teaspoons per gallon of water. You can water this by itself. Your ph seems off. You need to be adjusting your fert water ph after mixing with an acid or base for best results. See my signature below for things to use. Ph 6 works for both soilless and soil.




You will want to use the rate for spraying I suggested above. Ed Rosenthal is not a scientist but a pothead. He is still helpful. This is what he says:

Foliar feeding can also be used to correct deficiencies quickly. For instance, spraying a solution of a teaspoon of magnesium sulfate in a quart of water until it drips off the plant can treat a plant that is suffering from a magnesium deficiency. This provides the plant with magnesium very quickly. Magnesium sulfate should be added to the medium or hydroponic solution as well, so new growth has access to the mineral.

Stop foliar feeding buds at least three weeks before harvest so no fertilizer residue remains when the bud is picked.

If you really want to chance losing your buds go ahead and spray your plants so they can mold up and rot on you. If you used the dolimite lime in your soil mix you shouldn't need any epsom salts, but if you do choose to add them please water it into the soil and don't spray liquid anything on or around your buds.

Without a reliable PH test it makes it alot harder to determine the real problem, I wouldn't do anything drastic until you do that.

If you have been feeding every watering (even at 1/4 strength) you may have a buildup of salts creating nutrient lockouts. I would suggest to use plain PHed water matched to your specific grow medium everyother watering starting now. This helps to naturally flush salt buildup out of your medium without the shock of a complete flush.
