hurting plant?

rusto · Nov 2, 2006

Maybe? maybe not?

Heres the story, this plant was ONE bagseed i planted for fun awhile back and it started off great then had some problems i still don't understand totally what they were to this day. But anyways, it bounced back then I was like well whatever and set the lights to 12/12 because i was anxious to see the sex, it turns out its a female. So it was lookin good into flower and now ive been switching off feeding it normal drinking water and bio bloom. Im guessing there could be a ph problem somewhere in here.... But anyways more and more into flower it is lookin worse and leaves keep dying on the bottom. It is at about day 25 flower right now, YES UNDER FLUOROS ITS ALL I HAVE CAN WORK WITH RIGHT NOW DON'T WORRY HPS AND BIG ROOM IS COMING.

please let me know what you think...thanks

Just off hand, looks like magnesium deficiency. You cant enlarge your pictures to get a better look at how the leaves are going yellow. Are the veins green but the rest of the leaf yellow? Might need a dose of 1/4 teaspoon epsom salts + powdered gypsum per gallon of water along with the regular ferts. Do this till those symptoms go away. But, like I said I can not make the picture larger. Are the margins getting wavy...like going up and down as you look across the leaf? Have you tested ph? Directions are in my signature below. I am super stoned. :smoker:

Here is magnesium deficiency. Click on it to enlarge. Notice veins green but the rest of the leave going yellow.

Is biobloom 0-50-30? What is in it? Is there calcium and magnesium? You cant go the entire bloom time with no nitrogen. Your leaves will fall off.

Tip: Adjust fert water ph after mixing for best results.

1.1 - 2.5 - 2

That close up just looks like fert burn. Is there calcium in your ferts?

Here is calcium deficiency...

You would use the same gypsum epsom combo to cure this as well. Wont hurt the plant if your wrong.

Your ph could be low. Check it using the directions in my signature.

no cal

MynameStitch · Nov 2, 2006

how often are you using aand how much?

For one you have a slight nitrogen and magniseum issue.....

rusto · Nov 2, 2006

every other time and the amount as directed on the bottle

it gets nutes basically every 6 days

has a droop look to it , maybe over watering causing an N def??

rusto · Nov 2, 2006

no not overwatering at all, i water after it starts to wilt down even more and the soil is lighter

You should add calcium and magnesium to your ferts if needed. 1/4 teaspoon epsom salts + 1/4 teaspoon powdered gypsum per gallon of water along with the regular ferts. If the regular fert has magnesium, dont add the epsom. Powdered gypsum you can get at good garden centers. Just call around. Hoffman is a brand. You sometimes see it in small 5 pound bags. Epsom salts you can get at the drug store. I add the epsom gypsum combo every third or fourth fert with dol. lime in the soil and everytime if there is none. Be sure to adjust the ph of your fert water after mixing for best results.

thank you sproutco

rusto · Nov 6, 2006

today i am going to get some gypsum and maybe later tonight or tomorrow add it and epsom.

sproutco would you suggest adding those to a gallon of water or just to my cup of water?

sproutco · Nov 7, 2006

Gallon jugs that distilled water, drinking water, etc... came in work well for mixing up small batches of ferts. Dont use old milk jugs because there is milk fat in the plastic you can not get out. Since the situation appears critical, add 2x rate. 1/2 teaspoon of both powdered gypsum + 1/2 teaspoon epsom salts per gallon of water along with the regular fert. Regular ferts maybe only use 2/3 of the rate they suggest since your growing under low light conditions/florescent tubes. I cannot stress enough to adjust the ph of your fert water after mixing to about 6. Always use enough water to get runoff from the drain holes everytime. 20% of what you apply should come out the bottom.

For your next grow, you need to calibrate yourself so there is no guessing. There is a calculator in my signature to figure ppms of each element like 100 ppm nitrogen. It requires net weight from the bottle, total ml, ml used, and % of each element in it like 5% calcium. I will help you come up with a good feeding program once you do that. Try entering 1 teaspoon=5ml and see what the ppm is.

Today I watered with gypsum and epsom as directed. Right now they are still a little droopy though.

I am currently having the same problem. watered with epsom salt a couple days ago. no noticeable difference as of yet (good or bad).
