Yellowing on leaves of my Bubba Kush :( I have a girlfriend that is ill and needs it

Ok I took some good pics from my cell phone making sure everyone can see the problems with my plants, and hopefully be so kind as to help me out. Here is the info about the plants.

They are Bubbaz Kush plants from a medical dispensary in California. When I got these clones one was 4 inches the other about 6 inches. They had a bit of yellowing on the leaves. I Planted them in soil and added some nutes to it not much though seeing the size they were I thought it would be too early on. Please dont laugh at me about my set up. I have 2 48watt CFLs and a fan in a flat white painted MDF wood box. I also have them in 1 gallon containers, and feed them about every other day. I make sure the soil never gets too dry. The CFLs are studio CFLs not the cheap walmart or home depot types 5600K in a reflective light clamp holder.

I`m going to be getting a good size grow box next week and upgrading a bit so I can grow better right now though I need help on why the leaves are not only turning yellow at the ends with spots but also almost like they are bunt and the ends. I want to try to keep these as healthy as I can in the mean time till I get more funds next week to get a better set up. Just a FYI I`m trying to learn to grow weed not to save $$$. I have a girlfriend that is ill and needs weed to smoke so its not just for rec reasons. Please if anyone can help I would greatly appreciate your advice.

It looks like it may be a sign of cal/mag deficiency. Some kush plants are just sensitive they have the tendency to get yellow spots when everything else in the garden is green and healthy. Calcium and magnanese are also the first nutrients to get locked out if the soil is too acidic.

Easy fix bro, go to your local hydro store get a bottle of cal-mag, then go to your local home depot and get a bag of ironite. Now add cal mag in your nutes, get the Ironite sprinkle 2 teaspoons around the plant but make sure its no where near the trunk. I had that problem and I fixed it with these 2 products.


What kind of soil are you using? I dont see any perlite bro you might want to add some.

Yeah some cal-mag will solve your problems, I got some OG's that do the same thing without it.

must have over looked your comment thats so damn funny I was laughing so hard when I read what you did with the seed, thx for making me feel better about my first grow. To answer your question I am just using basic soil from a bag the planting soil. I dont really know what to use and what size pot I should put them in right now they are in 1 gallon pots. I been using so plant feeder and filtered water next week I will have more $$$ to get what I need for a good grow well at least I hope it will be a good grow.

Where should I get the cal-mag from?

Wet thx I will do this tomorrow I dont have perlite how much should I have in the soil? If you could wet just send me links from home depot or something so I know what exactly to get I would appreciate that very much so!

I would suggest getting some dolomite lime and top dressing your pots with it. It will help you avoid this issue later in the grow and help keep your pH in check...top dress at a rate of 1-2 tablespoon per gallon of medium and gently scratch into the upper 1/2 inch or so of the soil. It will take it a few weeks to kick in but the calmag will help until then.

i usually do 50/50 perlite and soil.

Thx wet I`m going to pick it up now and thank you everyone for all your help and guidance in this

Ok I did what you told me to do wet and others told me to do. I could not find cal-mag at home-depot ok ok.... I hate BSing I found it at Walmartbut cant afford it till next week. I went and got perlite as you told me to. I did a 50/50 mix of it, I also got Ironite and did what you told me to I mixed a little in the soil too not much at all I did not over do it. I also got a temp/humidity meter made by acu-temp or something. Anyhow it says my temp is 84 and humidity 46% is this ok or should I keep the door open to low the heat to around 80?. I`m including pics so you know I`m doing everything the "Weed experts" Tell me to do

Sorry about the spelling error I meant to say advice

Alex I also did what you said thx

[h=2]This might help you get to the root of your problem[/h]Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll. Possible causes of chlorosis include poor drainage, damaged roots, compacted roots, high alkalinity, and nutrient deficiencies in the plant. Nutrient deficiencies may occur because there is an insufficient amount in the soil or because the nutrients are unavailable due to a high pH (alkaline soil). Or the nutrients may not be absorbed due to injured roots or poor root growth.
The lack of iron is one of the more common nutrients associated with chlorosis. Manganese or zinc deficiencies in the plant will also cause chlorosis. The way to separate an iron deficiency from a zinc or manganese deficiency is to check what foliage turned chlorotic first. Iron chlorosis starts on the younger or terminal leaves and later works inward to the older leaves. However, manganese and zinc deficiencies develop on the inner or the older leaves first and then progress outward. Plants need iron for the formation of chlorophyll. Chlorophyll gives leaves their green color and is necessary for the plant to produce the food it needs for its own growth. Iron is also necessary for many enzyme functions that manage plant metabolism and respiration. Iron becomes more insoluble as the soil pH climbs above 6.5 to 6.7 (7.0 is neutral - below 7.0, the pH is acidic; above 7.0, the pH is alkaline). With most plants, iron can only be absorbed as a free ion (Fe[SUP]++[/SUP]) when the pH is between 5.0 and 6.5.
Other elements such as calcium, zinc, manganese, phosphorus, or copper in high amounts in the soil can tie up iron so that it is unavailable to the plant. However, a shortage of potassium in the plant will reduce the availability of iron to the plant. Cal/Mag is the way to go

ok well wet told me to get perlite and I did a 50/50 mix with the soil I also got Espoma 6.75 lb. Garden Lime from homedepot

To help with the PH problem, I added a temp/humidity reader to the mix and I even got some sand to make sure gnates would not mess my plants up. I did not have $$$ for cal-mag or a nitro reader but this will be next week so far I think I`m doing pretty good I`m listening to you all TRUST ME and appreciate you all helping a newbie that loves weed/plants more than you can imagine
