Leaves Turning Yellow

ShinKicker · Mar 25, 2016

So this is my first grow and despite some early on ph and nute issues I am at Week 4 of flowering as of today. However, this week I've noticed that some of the leaves are starting to turn yellow. I'm growing 1 blue dream and it should be 11 weeks to harvest. Any advice? Should the leaves should be turning yellow this early into flowering?

Can you provide some info on medium, what you're feeding and how often?

So I'm using pro pot mix with perlite and vermiculite and also I'm feed with Fox Farm Big Bloom 2 teaspoon in 1 gallon of water with 5 ml of cal mag every other watering.

Looks over watered to me. ...think you might wanna check the roots imo ..

flush and feed them, big bloom isnt adequate in itself. its more an additive. looks hungry, but its tricky feeding this far into flower. should be switching from veg nutes to flower nutes about now

Also, I just bought Hawaiian Bud & Bloom from Amazon and was going to give that a try. Is it too late to switch nutes?

Mate imo they don't look like they need nutes... they look proper stressed out ! .... What's the Temperature like day next night also the temp of your water your feeding them ? Are you letting them dry out before next feed ? With out more info on how your growing them it's hard to say what your doing wrong if anything ....

i feed big bloom in addition to my base nutes. grow big, then tiger bloom. thats the fox farm basic three part. idk what the hawaiian stuff is. theres quite a few A+B nute regimes, i had no clue so i picked fox farm trio, now i supplement to that, little at a time.

Yea use room temperature water and I wait till the container is light and the soil is fry before water them again, it usually last 3 days before I need to water again. I alternate between 7.0 Evian bottle water and my nute water (which I mix with 1 gallon of distilled water, 5 ml of cal mag, and 2 teaspoons of tiger bloom). I have a pretty small grow box under my desk about 9 IN. X 18IN. X 24IN. and the normal temp in there is about 25-30 degrees celsius.

Looking at your pictures I see several symptoms that tell a story as to what is happening. Plants that are displaying symptoms may be diagnosed by following a system of deficiency and toxicity of essential elements.

Lower leaves / older growth is yellowing - Nitrogen deficiency . growth restricted, plants generally yellowing (chlorotic )from lack of chlorophyll especially on older leaves.

Veins of affected leaves are reddening Phosphorus deficiency symptoms may included anthocyanin pigments. Plants will usually be stunted and maturity may be delayed.

Leaves are generally curving down and inward. Molybdenum symptoms of deficiencies usually occur in older to mid leaves first with characteristic marginal scorching and or leaf cupping.

To make a long story short - you need a complete feeding program that is able to supply all 16 essential nutrients for plant growth. Always check/ adjust PH and your PPM for optimum growth and net results.... Getting your entire grow dialed in and running at its best sometimes takes some fine tuning.

Happy growing

Definitely it isn't getting enough nitrogen. I want to say not enough phosphorus too judging by the necrosis. Either not enough nutes or the soil needs fixing. You need to test your soil or you won't get to the root of the problem.

Mate can I suggest next time you grow using coco as a medium. I find with soil that's it's hard to get all the elements correct because you don't know how many fertilisers, additives the soil has in it. Coco is 100% free of all I have just mentioned which means yOu control what your plants are being feed, not the company that you purchased your your soil from.

I have had nothing but 100% top class yields from using coco as a medium. You can then choose Nutes that are especially designed for coco. I gureentee you will have more success this way.

Sorry I cannot help you with your current issues, but I hope if you use the coco you will have success.

"I gureentee you will have more success this way."
What exactly does that "gureentee" entail ? Money back?

Ha mate. Not money back no. It's an easy forgiving medium to grow in.
