Phosphorus deficiency??

so i have been having a problem with my plants in veg. at first i thought it was nutrient burn so i flushed the crap out of them. i left on vacation for a week and had my girlfriend looking after my garden.. when i came home i found that what i thought was nutrient burn had gotten worse after the flush. what do you guys think?

are you using tap water?

yes, i always have tho and have never had any problems with it..

seems to me you have either a salt build up hich seems strange so young or maybe your ater has fluctuated some ho and the slats in it are causing either a change in your ph or maybe it's so hard your getting lock out IMO.
What is the starting ph and ppm of your tap?

well it used to b at 7.0 ph and 400 ppm ill go check it out and see if its changed.. all though im not having any problems in my early or late stage flowering plants which also use the same tap water

IMO- Magnesium Deficiency.


Good Luck on Your Grow

Well if the flush made it worse it's probably a nutrient deficiency. That could be an actual deficiency, or a pH lockout type of scenario, or an excess of one nutrient making another unavailable.

Have you done ANYTHING different in the last couple weeks or say 5 days prior to seeing the symptoms? Is this your first grow?

Personally I would not venture a guess, but I hope you can get it sorted out.

well my batteries r dead on my ppm meter so ill have to get back to you on that one but the water is still 7 ph..

AimAim: i foliar fed them AN's revive on them when i noticed a cal/mag and what appeared to b an iron def.. i had never used it before. oh and this is not my first grow i have years of successful grows under my belt

beautiful plants...plus rep

i had been using a diluted dose of AN's grow ph perfect.. i read somewhere on here that the ph perfect wont have a "perfect ph" if u rnt using the recommended amount on the bottle, anyone know if thats true?

kind of hard to tell but the new growth looks good. watch the nutes and watering and let it grow. GL

i did hear these 2 strains (cinderella 99 and elephant stomper) are cal/mag whores and have had cal/mag deficiencies since the the begining.. but could that cause this much damage?

Check the ppm or and ph of runoff water . Foliage looks nitrogen starved twisted leaves show mg / cal imbalance
a raise in ppm of runoff means too much nutes usually
flux in ph of runoff means nutes locked up.
I pearsonqll hag had great success with neemand protect from dyna add 5ml of base nute an 5ml of mgsul. Follow up 3 days late with neem ksil yucca an 2.5mil calcium

Over water/ root rot possibly?

Is the new growth slowed down?
What soil are u using?
7.0 ph water before nutes isnt right for soil.
6.2-6.5 after nutes.

yea at this stage i would like to be seeing some explosive growth.. i was gone for a week and expected to see bushes when i got home. im using promix hp. i havent tested my ph in awhile i used to regularly check ph b4 nutes, after nutes, and runoff but it was always the same once i started using the promix and ph perfect. ive been using ph perfect bloom for some time now but now that im thinking about it i just recently switched over to the ph perfect grow, i had a big bottle of gh floranova grow that i wanted to use up before switching. and like i said in a earlier post i have been using a diluted dosage of about 50% on the ph perfect grow do i need to use the full recommended dose in order for it to fully "perfect" my ph?

maybe a potassium deficiency or a magnesium deficiency.

I've never used p.h. perfect but i saw the video on youtube. My guess is that only works best with r.o. water. Tap has too much alkalinity to change the p.h. For example, it only takes 3 drops of p.h. down to lower a gallon or r.o. water a point but like 30 times that to lower tap water a point.

wow, so i guess flushing it with straight non ph'd tap water could have made my medium quite alkaline. which could b the reason they looked worse when i came home. i havent fed them for weeks thinking that i had overfed them as babies so when it got worse i started thinking deficiencies..
so seeing as how i dont currently have an r.o. system, would it be best to go buy a bunch of gallons of drinking water from the store and flush them out with say 1/4 strength nutes?

sorry for the bump but i was hoping to do this on my lunch break
