The leaves of my plant at the very top only, are five and seven bladed at the base of the blades where they connect is yellow getting green halfway toward the tips . I have no way to post a pic unless someone can tell me how to use my cell to do it . Ph is 6.3 . Week 4 of veg. growing in miracle grow / perlite soil mix . White widow from attitude . I think it looks like a Mn deficiency . So does anyone have an idea of where you get chelated Mn and how to apply it ?

Also they may have had too much water but are not droopy anymore and standing up pretty good now . I fed for the first time with a Technaflora starter kit/ Recipe for success yesterday . This is the second time using this my week 4 in flower are looking good with no such problem at all. Same soil and everything .

Ok 1/2 strength feeding shows a fairly good improvement 2 days later. Photo looks no different though . I would like to move light closer but am concerned that I should wait until the color comes back some more . Either I have just been lucky in the past or what I don't know , but I have never seen this kind of color before . Also I have never paid for seeds until now , just saved a seed whenever there was one from something really good . I'll post another pic in a day or so when theres a change . I don't know enough about deficiencies or ferts to isolate problem , all I can think to do is feed with a complete veg. fert mix every third time I water and hope that resolves the problem cause it has definitely stunted the growth of this plant . I have it under a 600w mh and it should have taken off by now.

NITROGEN (N) Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

PHOSPHORUS (P) Slow or stunted growth, red stems. Smaller leaves that are dark green. Lower leaves yellow and die. Add chemical fertilizer containing P. Affected leaves will not show recovery but new growth will apear normal.

POTASSIUM (K) Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

CALCIUM (Ca) Lack of calcium in the soil results in the soil becoming too acid. This leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar feeding with one teaspoon of dolomatic lime per quart of water until condition improves.

SULFER (S) Plants suffering from S definciencies exhibit yellowing of new growth. Mix one tablespoon of Epsom salts per gallon of water until condition improves.

MAGNESIUM (Mg) Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

IRON (Fe) Leaves on growing shoots turn pale and veins remain dark green. pH imbalances make iron insoluble. Foliar feed with chemical fertilizer containing Fe or rusty water.

MANGANESE (Mn) Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

BORON (B) Growing shoots turn grey or die. Growing shoots appear burnt. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water.

MOLYBDENUM (Mb) Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.

ZINC (Zn) White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.

OVER FERTILIZATION Causes leaf tips to appear yellow or burnt. To correct soil should be flushed with three gallons of water per one gallon of soil.

Leaves toward the top have died at the tips and along the edges . Also leaf texture is noticeably not normal . Thanks for the link , I saw those pics and still do not know what this is though . ph is same 6.3 . this plant is going to die soon if this keeps up .

This blows I think I'm gonna trans plant it into fresh soil mix , cause it looks like a nute burn to me . How I don't know a soil hot spot or what , I just can't believe it but maybe something got into it when i was baked and in there watering and not paying attention .

Hey did you ever fix this? I am having almost the exact same problem and have not been able to figure it out. First i thought it was PH because i found out my tap water ph is a bit high @ 7.4, but even after a week of using ph adjusted water new growth is still yellow..... almost white.
Thanks
