I'm having some problems with the plants. There not looking so healthy. They are curling and turning yellow.

Temps around around 80-88 deg.
Ive been watering them only when their soil is dry. Ive been trying to keep them on a light fert of tiger bloom.




This is the newer strain that has just this one leaf and it is real dry.

Check your N, often times plants need a boost of it during flowering.

-C

also if it helps it started more from the top of the plant

They are not looking any better. Im thinking its a sulfur deficiency.




Ive been just watering them with just water no ferts.






The stems are all purple and the leave color and drooping is why I would think it was sulfur.
any input??

Looks like maybe Mag deficiency. What's ur PH run off?Mg-deficiency is pretty common since marijuana uses lots of it and many fertilizers don't have enough of it. Mg-deficiency is easily fixed with ¼ teaspoon/gallon of Epsom salts (first powdered and dissolved in some hot water) or foliar feed at ½ teaspoon/quart. When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil for Mg. Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.

well as of right now i dont have a ph meter. I know it is a very important thing and need to pick one up soon. But I have some epsom salt and i am going to try it out because the problems that it may be are all almost treated with epsom salt. I have seen 1, 2 and even your 1/4 teaspoons pergallon. I guess what I will do is just start small see howit works? If it doesnt work give it a little more.

I watered them yesterday a good amount of distilled water and their soil is still damp, should I wait till the soil dries up to water them with the epsom water?

your plant needs more nutes man!!!

all those pics look like deficiencies to me.

up the nutes!

[nvmywrx]

im weary about giving them more nutes because the plants on the tops have rust spots. could this be nute burn?
I would like to try to epsom salt first.
