What does so far no positive effects mean exactly?

And whats the ph of your water and soil runoff?

[Poetik Irony]

it means that niothing benificial happened its still just continuing to get worse , an as far as the ph it ranges between 6.8 an 7.3 , about 2 sets of leaves died today an the sets right above appear nice an green minus a few dead spots as for the top its lookin brilliant more pistils an crystals everyday

[partcleguy]

Well it could be a Phosphorus deficiency. If I remember correctly, it shows up as yellowing in the older leaves first. It could also possibly be they're rootbound? What size pots you got them in? If its working its way up the plant that probably rules out over fertilization...

[Poetik Irony]

Its In A 5 Gallon Bucket So I Think Its Safe To Rule Out Root Bound An It JUST KEEPS CLIMBING ITS WAY UP THE PLANT!!!!! the start turn pale green an gettin dead spots then they turn pale yellow wilt an fall off!!!!

Screaming at the people who are trying to help you will accomplish nothing. You aren't the only person with a problem and some people have lives and jobs that interfere with their ability to give you free advice at the drop of a hat.

here some possibilities according to Cannabis Nutrient Disorders

3) a) Margins of the leaves are turned up, and the tips may be twisted. Leaves are yellowing (and may turn brown), but the veins remain somewhat green. >> Magnesium (Mg) deficiency.

4) a) Leaves are browning or yellowing. Yellow, brown, or necrotic (dead) patches, especially around the edges of the leaf, which may be curled. Plant may be too tall. >> Potassium (K) deficiency

6) a) Tips of leaves are yellow, brown, or dead. Plant otherwise looks healthy & green. Stems may be soft >> Over-fertilization (especially N), over-watering, damaged roots, or
insufficient soil aeration (use more sand or perlite. Occasionally due to not enough N, P, or K.

13) a) Leaves twist, then turn brown or die. >> The lights are too close to the plant. Rarely, a Calcium (Ca) or Boron (B) deficiency.


by the looks of it, this is most likely a deficiency that may be corrected with either some additional fertilizer or a micronutrients. (just a thought)

It might be helpful if you post some pics of your plants.
