so based on the larger buds pics when is the best time to harvest? Also based on the harvesting question, when should I stop giving the plant nutes?

how long have they been flowering? you flush the plants by adding no nutes for the last two weeks

Hello All,

I need help with my plants. The plant leaves have yellow and brown spots, and leaves are starting to dry. I have moved the hps light back further so there is not much heat hitting the plants. I have been feeding the plants only PH'd water about 6.8 with no nutes. Should I start giving it diluted nutes? What should I do to turn my plant back to green? It kinda sucks that the leaves which are growing by bud are starting to have these yellow dots. Before it was only the fan leaves. Also should I cut the fan leaves which are turning yellow and brown? Here is a pic of leaves by the bud having yellow/brown spots. Please advise.

here i think this is the problem

Calcium (Ca) -Macro Nutrient and an Immobile element.

Calcium is another important element that helps the plants cell walls, cell division in making the plants stems, stalks, branches stronger, as well as contributing to root growth, mostly the newer root hairs, Calcium also helps enhancing the uptake of K in the the plants roots. Calcium moves really slow within the plant and tends to concentrate in roots and older growth.



When plants exhibit a Calcium deficiency the younger leaves are the first to show it as well as older leaves. The Leaf tips will die back, the tips may curl, and growth of the plant is stunted. The plant can show a weakness in the stems and branches, as well as a under developed root system that can lead to bacteria problems with roots dieing off. Having slow plant transpiration rates can aggravate the uptake of calcium. Make sure your soil isn’t very acidic, for calcium gets harder to be absorbed through acidic soils, Which leads to having a plant that is deficient in Calcium. The leaf tips, edges and new growth will or may turn a yellow/brown color that happen in spots and often surrounded by a sharp brown outlined edge and then the leaf tips die back. If too much calcium is given at an early stage of growth it can stunt the growth of your plants. Having to much of calcium will also flocculate when a concentrated form is combined with potassium. The parts affected by a calcium deficiency are the roots. Stem or petiole, young or old leaves.

Too much Calcium will lead to other micronutrient deficiencies. Calcium fixation is caused by many types of mediums such as: clay soils, unbuffered coco and humus. The lime tends to bond to these soils very easily. The stems of the plant will not be able to hold the plant up and will exhibit a white brown in between the veins of the leaves when having too much calcium. Also having to much potassium and or nitrogen will cause a calcium lockout.



Problems with Calcium being locked out by PH troubles

Very acidic soils with excessive potassium, dry and or wet soil. Lack of calcium in the soil may cause too acidic soil. This may cause to Mg or Iron deficiency or very slow stunted growth


Soil


Calcium gets locked out of soil growing at ph levels of 2.0- 6.4
Calcium is absorbed best in soil at a ph level of 6.5-9.1 (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a
Calcium Deficiency.


Hydro and Soil less Mediums

Calcium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0- 5.3
Calcium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.4-5.8 (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Calcium Deficiency.




Solution to fixing a Calcium deficiency
To fix a calcium deficiency you can treat by foliar feeding with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Or you can take crushed up dolomite lime or garden lime in a gallon of water and water it in the soil. 1 to 2 teaspoons per gallon of water, which will be slow acting. Garden Gypsum, which is medium absorption. Limestone, which is medium absorption, Rock Phosphate and Animal wastes which are both medium/slow absorption. Note: Caution when using gypsum to an already acid soil (pH that is less than 5.5) can have a very bad effect on different types of plants by effecting the absorption of soil aluminum, which is poison to plant roots.


Now if you added to much chemical nutrients and or organics, (which is hard to burn your plants when using organics) you need to flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.




Pictures 1-2 shows calcium deficiencies. First one shows late, 2nd one shows early development.

Thanks SICC, your always giving good advice. I did flush my plants out with alot plain water. I think I am just going to using regular tap water which the ph leven is between 7-8 with no nutes. Would you advise the same? The nutes I have is grow big, big bloom, and tiger bloom. Would you recommend I use any of the nutes with tap water? In the meantime I am going to be using regular tap water until you advise. Thank you again.

Well here is your problem

Calcium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.4-5.8 (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Calcium Deficiency.

the water your using has a pH that is too high, you need to lower it

Hey SICC, thanks for the fast response. These are pics of the plant that was transferred into a soil pot. I have been feeding it water with the ph level of 6-7. If its in soil should I increase the phl level? And should I use any nutes at all?

Oh yea thats right,

well here is the soil part

so i would say you need to raise it a lil bit


EDIT: when to do plan on flushing?

I already flushed it, but I can flush it again. Also shouldnt use any nutes correct? Thanks SICC.

[quote="SICC";2134943]Yea, if your flushing, dont add any nutes, no problem man, i hope they pull through :leaf:[/quote]

Ok coo thanks

The lowryder sprouted on 1/10/09, so its day 45 from seed. The lowryder is nowhere close to near harvesting. The bud sprouts are showing everywhere but I though its suppose to be harvest in 60 days. LOL do I have some special lowryder? I dont expect to harvest it anytime soon.

Pic 1: Top view of the plant, which you can see plenty of bud sites, which are still really small.

Pic 2: Top view on at a angle. Again you can see multiple bud sites.

Pic 3: Zoom of the top bud of the plant.

Pic 4: Side view of the plant, might be able to see multiple buds sites from top to bottom.

Pic 5: Mid level bud site

Pic 6: Lower level bud site.

Those are just set dates, every plant finishes at there own rate, shes lookin good man, nice and healthy :weed:

Also since the last week the plant has been getting 14 hours of cfl lights and 8 hours under 250W hps. The height of the plant is between:

18 - 19 inches
45.72 - 48.26 cm
0.45 - 0.48 meters

Yeah she seems like a slow bloomer but I think she will do great.
