Is this Phosphorus (P) deficiency?
Im a new grower please help me out,

ok here are 3 pics, they are of 2 different plants, 2nd week of flowering /12/12 just gave them a solution of neptues and a 3 part GH floragro floramicro and flora bloom all about half strength also pictured. I used neptues before at a little less than half and it seemd to to ok no problems.

I was thinking it's a "P" issue, whatcha think? Im going to get a soil test kit in just a bit..

I will gladly give +rep!:bigjoint:

Also you might try adding a cap full of hydrogen peroxide per gallon of water. That will help the roots get more oxygen. Very good for over watering and hydro/ebb flow

Well Same Idea but you need the stuff available at the hydro store.. It will cost more and this shit u do not want on your fingers or hands... Remember when u put the stuff in your water, u should let the water set 20Mins before adding your nuts and water right always since the extra molecule is radical and will dissipate right away. I dont know if it is worth the money!! They clam board leaves but u need it right from the get-go!!

It kinda looks like your plants are in their growth stage in flower-if thats so than that could compensate for why they have under gone some stress by your heat of the bulb.. Check out if your leaf tips are burnt as well, if so that would indicate nut burn. But prob not if you are going half strenght and your plants are that mature...

Hydrogen Peroxcide is found in wal mart, etc. It's only 3% I think. I use it once a week. Does nothing for smell taste, etc.

Here is some info on the product-u need to go to the Hydro store for this.. I have used this.. Again like I said, I would go another route before trying h202.. I posted this so you guys could have some info on what I was talking about when I said 35%.. This is made by grotec called Super Oxy.
Super Oxy™ H2O2
35% H2O2 promotes thicker stems and larger leaves by providing additional oxygen

Hydrogen Peroxide is used through irrigation and is composed of water and oxygen which stimulates nutrient consumption. A higher oxygen level in the nutrient solution will improve the plants ability to take up the available nutrients from any medium. Proper use will enhance thicker stems, larger leaves and shorter spacing on stems. Can also be used as a cleaning agent in irrigation systems and/or propagation.

From Jorge Cervantes;
"Hydroden Peroxide (H2O2) is similar to water but carries an extra, unstable, oxygen molecule which can break down into a reactive atom and either attach itself to another oxygen atom or attack an organic molecule.
Used in horticulture, hydrogen peroxcide provides a host of benefits by cleansing water of harmful substances such as spores,dead oraganic material, and disease-causeing organisms while preventing new infections fro occuring. Itremoves the methane and organic sulfates often found in well water as well as removing chlorine from tap water.
Hydrogaen Peroxcide is especially useful in hydro, where over watering can ba a problem. It prevents oxygen depletion in the water around the roots, leading to better root growth. A solution of hydrogen peroxide can be used to stearlize seeds resulting in better germination rates.
Hydrogen peroxide is dangerous at high concentrations (35%) and will damage skin, clothing ,and most anything it contacts. Lower concentrations (3%) will still need to be diluted before use, though they are not as toxic to the gardner."

wow replies lol
I dont see how it could be light burn, these are all nice cool floros (fan cooled) even the plants can touch them without a problem, they use to be closer even.

I added more nute to it last night, at first the P test said depleted but like 30mins later it was the opposite....

The other plants aren't having this problem and there is another that is much bigger, and almost touching the light and she doesn't show any of that at all.

When 12 rolls around and the light are on Ill retake pics.

I will add the 3% hydrogen prox. on my next watering.

I got drunk and stoned and xfered 4 of my plants from my small hydro setup and put them in soil so I hope that worked ok. I know it's stupid but my hydro is too small so they had to goto buckets.
