Do these leaves look ok or is something up?

View attachment 1396332 is the leaves color normal or is it a sign somethings wrong?

those plants look great, but sometimes leaves that are discolored are early signs of over fertilization, soon after it will start to burn at the tips, try flushing with water next watering then reducing the ppm by about 50 the following watering and see what happens

DO you know what PPM you are feeding them at the minute?

no i dont, how do i know? i havent fed em full strength nutes yet only half what it says to, i was planning on just using plain water next time anyway, these plants did suffer some nute burn early in but i tried to sort it

i think it kind of looks like a Magnesium deficiency. maybe try 2 tbs of molasses in a gallon of water. has magnesium, plus should make ur buds bigger

I was also going to suggest a slight magnesium def this may have been cause by the initial root burn not allowing the roots to absorb the required amount. I would defo do a flush and also try the molasses, the posts lately are right on the ball!

You're right to be worried I think. That could very well be the beginning of some coco nutrient toxicity. Similar to this issue which is a little further along:


Next time you water use maybe a 75% strength and make sure you get like 1/2 of what you add to drain out the bottom. You might still wind up seeing something that resembles magnesium deficiency in those leaves in the long run. If the "meat" between the veins begins to go very pale I suggest you take a liter of water and a pinch or two of epsom salt with a drop of dish soap and spray those leaves just as the lights are coming on in the morning. Aim for the underside and make sure you get the whole plant.

Feed again a few days later with the same strength solution and same amount of run off and you should be balanced back out enough to go back to maybe 90% of what you had been doing. More run off in the future will help keep your plant looking lush, especially during flowering.

Snow Crash, I understand that the epsom salts have a high magnesium content but what does the dish soap do? and can you use any type? Sorry for my ignorance.

Thanks for all the replies, +rep

The dish soap contains a surfactant that helps make the water, wetter, this results in better coverage of the leaves. You don't want to foliar feed at night because it will raise the humidity and could create a hospitable environment for mold. Getting Magnesium and Sulfur right to the leaves will help decrease the rate of cannabilization and could preserve the leaves long enough for the recent nutrient fix to take affect.

If you give me the ml per gallon that you are using I can approximate the EC of your solution for you. You definitely need to get them down in the media. Run off is REALLY important for that.

i use canna's terra flores and it says to use 50ml per 10L so i used 25ml per 10L i also used cannazym which it says to use 25ml per 10L but i used 10ml per 10L

EDIT: I think 10L is 2.6 US Gallons but not sure

Oh, wow... That's really actually very little nutrition.

Maybe 300 to 400 ppm depending on your water starting point.

Just make sure you are getting plenty of run off. I thought that was coco at first but now I know it is Terra. It could be that you're running a little acidic, which is starting to lock out micro-elements. It is important to have a grip on the pH, keep it over 6.5 for sure, 7.0 might be better for this peat based situation.

i have been keeping my ph around 6.3-6.5, should i use full strength nutes next time then or not, and what ph, the nute bottle say 6.2 but i dont know.
and also i always get a decent run off

I'd use 6.5 to 6.8 pH and I'd use full strength next time for sure.

Not so certain about the nutrient toxicity now that you've said you're using such a weak strength formula. Probably pH when looking at the evidence now. Bringing that up a little bit should help over the long run.

ok thats what i will do, thanks for all the help snow crash

Top class info mate, thanks for that +rep
