New Gardener needs help

Hello, im toonstoner from north east UK, and im doing my 1st grow, i got a couple of clones (himalayan gold)from a mate, when i got them they were'nt inthe best of condition and needed to go straight on to flower cycle, about 4 wks in now and one plant is doing great and the other is working okish, but over the last few days the larger leaves have started to yellow and crisp up dry at the ends, ill add a couple of pics, any help would be cool

many thanks

Healthy plants start to yellow at the end of their flowering stage.
But 4 weeks is too early to be seeing this.
You need to increase your nitrogen in your nutrient solution.
Some molasses would be good right now, too.

Molasses, interesting, how does one go about this and what benefits does it offer the plant?

Thanks again

You could buy some pure molasses from your local supermarket and feed it to your plants in the water.
Just add about 4 tablespoons per gal. This is an abundant supply of carbohydrates(sugar/energy) for the plant to eat up.

Looks like a nitro deficency to me too. Dont add too much in flower or it will retard the flower growth and make the smoke harsh if you dont flush it out.

Thanks guys for the advice, one last thing, can i add the molasses to my nurt mix?

Peace

i beleive you can. i havnt use molasses yet but will try this year. i think you add about 1 -2 tsp. per gallon of water. i also think there is a certain type to get like the kind with no sulfer in it or something like that. im going to research it more myself before first use. sorry i couldnt be more specific.

guys, stop giving misinformation about molasses and get your facts straight.

The roots are unable to absorb (through active transport) carbohydrates and other larger molecules.

Molasses is mostly beneficial in an organic grow where the microherd breakdown the sugars into something the roots can absorb. In essence, the molasses is food for the micro-organisms in the soil that help the plant; rather than the plant itself.

My plants also started yellowing at the 4th week of flowering. Just drop the N and up the P and K, as these also look a little nute-burned (too many nitrates).

Organic or not. Molasses is beneficial. FACT
Micro-organisms are everywhere! His root system is far from sterile. FACT.
This is happening to older leaves not newer ones. FACT
More then likely a deficiency, then a burn. HYPOTHESIS

Hope that's straight enough for you.

The only benefit it could have is adding more micronutes to your feed. Apart from carbs, molasses is rich in Magnesium, Potassium, Calcium, Iron, Phosphor and others. However, if you already have enough in your soil (e.g. dolomite lime, epsom salt) then wouldn't this cause a salt buildup, possibly blocking out other nutes?

Of course MO or everywhere, but specific types of bacteria and fungi are beneficial to the soil and roots, and they're the ones that breakdown organic material (such as molasses) so that the roots can efficiently absorb the nutrients. If roots were able to absorb all the sugar the plant needs (and i do believe that roots are able to absorb monosaccharides such as glucose, but not disaccharides like sucrose) then why photosynthesize at all?

Just because you believe something doesn't make it a fact.
