yellow, bright green and dying leaves.... help?

iv had the majority of these plants for almost 2 months and they have been preflowering for 2 weeks or so. they always had a yellow leaf here and there but that was on the large sunleafs at the very bottom. now new leaves and tips r starting to turn aswell and im getting worried. iv recently started feeding something to them called bloom which is a 4-9-8 solution. the reason why i bought this formula is because i believed they might be deficient because the only fert iv been giving them is a cup of pee in their water. iv only watered them twice witnh the solution but it even seems like its aiding in the yellowing.... but im not sure. il try to upload some pics but on previous attempts it wouldnt allow me.

here are pics... pleae take time to check some out

thats clearly not the problem.... please take time to look!

Mobile elements are more likely to exhibit visual deficiencies in the older leaves, because during demand these elements will be exported to the new growth.
Nitrogen (N)

Nitrate - Ammonium is found in both inorganic and organic forms in the plant, and combines with carbon, hydrogen, oxygen and sometimes sulfur to form amino acids, amino enzymes, nucleic acids, chlorophyll, alkaloids, and purine bases. Nitrogen rates high as molecular weight proteins in plant tissue.
Plants need lots of N during vegging, but it's easy to overdo it. Added too much? Flush the soil with plain water. Soluble nitrogen (especially nitrate) is the form that's the most quickly available to the roots, while insoluble N (like urea) first needs to be broken down by microbes in the soil before the roots can absorb it. Avoid excessive ammonium nitrogen, which can interfere with other nutrients.
Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.
Nitrogen Deficiencies
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.

Nitrogen deficiency my friend!

Hope this helps.

I could only stand to look at one pic. It looks to have a few deficiencies, then I see some burn on the tips. So I would say a PH problem, what is the waters PH, what are you using for soil? Do you have a PH meter? test the run off, not that it will help you a lot, but might give you an idea of what is going on. Let us know... JR

Im total noob so my word aint much but Those tips are defo nute burned. The same thing happened to mine after I added nutes for the first time two weeks in And the second time when I added nute crystals in the soil when repotted . The soil I used said it would have enough food for 4 months and didnt believe it lol (probably not 4 months worth. but defo didnt need any all veg cycle.

So I flushed them i.e the nxt time you water. Do it till you get water coming out the bottom of pot then slowly do it again and again till the run off goes clearer. After flushing I always have little leaves at the bottom that were burned at tip turning that light green colour and dying. enclosed attach. I dont have any large fan leaves dying like that though. which could be some nut deff. but I really havnt seen that side of it yet.

The leaves look quite droopy to me my plants look more perky. (pros correct me if Im wrong) I let mine go nearly bone dry b4 watering again. I can usually tell by the weight of the pots how much or little is in

Do you monitor the ph levels at all. you can pick cheap kits up 4 under £10. you will have used similar test in chemistry lessons. you can get these from ebay or aquatics shops/pet shops in the tropical fish part. A low ph indicates too many nutes. Maybe a good step to take b4 flushing or adding anything else

1 last note too much pee makes your bud taste like pee. My freind had some once it fuckin reeked tasted weird but got us smashed.

I spent a weekend checking out all these posts in here. a wealth of knowledge.

thanks guys... im willin to bet it is a ph problem. i have a very simple tester thats not easily used on soil. il def check the run off. i dont have an over or under watering problem i can assure all of you. my guess is the ph level is off locking up nitrogen makin my plants deficient and weakk in chlorophyl. also i have a little nat fly problem. i dont know for sure but my ph could be around 5.3.... hard to tell tho so il go testsome run off.

ph: somewhere from 5.8-6.3..... its quite the range but my ph tester is not accurate, esp cuz my watering solution is a tint brown from nutes, so the run off is even darker.
