Inexperienced grower needing advice.

My plant is Northern Lights FEM from Ministry of Cannabis. I have been using the Greenleaf Nutrients line. Megacrop, Sweet Candy, and Bud Explosion. My soil is Foxfarm Ocean Forest. I'm 2-3 weeks into flowering watering with a 3 times nutrient to one time water schedule. Just started noticing a day or two ago the leaf curl. Just noticed the discoloration today. As far as training I topped once, tried a little LST, and have defoliated. My last watering I used 5 grams megacrop, 2 grams sweet candy, and 2 grams bud explosion. I use tap water which comes out of my faucet at about 60ppm. PH my water to 6-6.5. I suppose all I need to know is if anyone is familiar with this issue and type of discoloration. Any advice to fix it is appreciated.

Cut back on the feedings. The yellow and curling leaf tips are signs of nutrient burn. Also looks like it could be too much Nitrogen as your leafs are dark green and shiny so I’d make sure I’m not using any nutrients that hare high in Nitrogen.

Try feeing every other watering or every 2 waterings.

Think your overthinking this .... not sold on nute burn .... couldbe nothing hopefully not pest ... try looking under leaves ... still try not to feed it every watering if this persist..

So you think watering two times nutrients then water may help? I went over the whole plant with a magnifying glass and couldn't find pests of any sort. Maybe I'll stop using the sweet candy and bud explosion for a couple waterings. Just use megacrop cut back a little.

that could work ... I saynever give it nutes more than twice a week so if your watering it every 4 days than feed every time .... if your feeding every 3 days maybe skip every other time .... you get me ..

OP the ones in the 3rd picture look like sulfur deficiency. If you look up a leaf chart the tips of the leaf turning yellow on the edges is sulfur. I’ve had that before as well.

I had theses same rust spots on OG kush a couple weeks ago. I added a little cal mag and 48 hours later it was gone, maybe try a wet paper towel/tissue and softly try and wipe it off, just a thought
Keep it green dude

yes I think he has cal and sulfur def both

That damage is a water Droplet from watering, whist the lights were on, don't wet the plant leaves.

nothing to worry about.

Thank you for all the help guys. I'm going to water with clean water. Then the next watering I will water with megacrop and calmag and see if that fixes it. Thanks again. Great community on here.

If you continue to give nutrients you will kill your plants. Ocean Forest already has nutrients mixed in. I wish people would read the contents that are printed on the bag, but no one ever does. You're feeding way too much even if your soil had zero fertilizer. Don't flush, but give nothing but water when the soil is dry. If you're lucky, your plants will live.

I'm sorry but I don't agree with this. I know ocean forest has nutrients mixed in. That's why I bought. While it is enough for the first stages of the plants life, it does not sustain well for an entire grow. These problems just started a few days ago. I have been feeding since just a few weeks into veg. My plant is not at risk of dying. It has minor leaf curl and very little spotting. I have been feeding a little heavy though.

the spots are from water with nutes - it burns leaves....

as for curling and burnt leaf tips, u are overfeeding her.....
