3 days in flower. Nutrient deficiency or what?

Hello to everybody.This is my first grow so im a kind a scared when something changes on plant . Im growing one plant in 2.5gallon pot, soil mixed with perlite and vermiculite, waterd with water ph 6.0-6.5, fertilized first time a few days ago (i think 7 or 8 days ago with 1/4 mix). Well here is a problem, since i switched to 12/12 to lower leaves on plant started to yellow and drying, some of them just drying and curling.Temperature in box is 80ºF, humidity around 30-40% when light is on, when off temperature in box is around 70ºF and humidity around 50-60%. Light is 150W HPS.

Here are some pictures. Any help ,advice is appriciated.

So what do you think ,should i give them more food ?

maybe lack of nutes if you only used a 1\4

No ^^^^^^
in picture 2 you can clearly see the tips of leaves are burnt , this could be nute burn ? , how is your PH ?

Clonex thats from before, once i previous soil i get a little burn( too strong soil), but this what you see its not new its an old burn , new grow is ok.

I dont have PH tester for soil, but soil PH from bag says its 5.8-6.5ph, the runoff water is 6.5ph-6.8ph

If you're doing a scrog I think you could expect some lower leaves that don't get much light to die off, everything else looks really good

Nutrients will cause your ph to change , how do you know the run off is if you do not have a metre ?

Loooks normal to me. Plants always lose lower leaves fairly early in flower, then a few throughout.

Tops do that to me as well, early in flower, when they start stretching. Once the stretch stops, it greens back up.

Ok.Thnx guys. Clonex i have ph test for aqurium water( droops) , and i cant messure soil with it, only liquid.

If you're using the right soil and the right nutes, you don't have to worry about the pH of your soil. Keep the pH of the water between 6.3 and 6.7. 6.0 is too low for soil grow. Light penetration is probably your problem. Dropping lower leaves is not a big deal. Your plants look fine to me. You might want to include some CalMag+ to your waterings.

test your water, then add a soil sample, test again...... and see wich way on the ph scale it takes you...may help ?

DawgMountain are crushed eggshells ok to add in water for some calcium? Or i should buy some real stuff?thnx

bump...
DawgM my fertilizer have already Magnesium in it (the NPK(Magnesium) ratio is 4-7-7-(2) ), so i think i should be ok .Now i wanna know whats ok to add for Calcium? are aggshells ok?

thnx

Yes but you can ph the water you are putting into your soil , after a few waterings your soil ph will stabilize.

Normal, don't worry.

Clonex i ph-ing the water with vinegar or lemon juice so the PH of water i putt into soil is 6.0 - 6.5. thnx for replys.

edit:Still dont know if the egg shell is good for Calcium add into water?

Yellowing of the lower leaves is normally a Nitrogen deficiency and bloom nutes don't usually have enough N in them so you might want to look in to adding some more Nirogen

Never tried egg shells Umbre , guess it would work if they contain cal , why use lemon juice , ph down is really cheap and designed for the job , you have to crush the shells i take it ?

Hello .I dont have ph down at the moment ill go and buy it when ill be in the city , thats why i use lemon juice . Well here is she 1 week into flowering. I added 1/2 dose of fertilizer 2 days ago, next day i noticed some new grow was curled under.Today i added some eggsheels to my soil for somme Ca add. Btw i noticed vermiculite that i use already contains CaO (Calcium Oxide) in ratio of 1-5%.
Here are some pictures. Comments welcome
