leaf tips are yellow

by hpst about Mon at 9:03 PM - report

 My plants are growing well. Using organic soil. I'm being very careful with the watering. I've grown AK-48 before & it is very easy to overwater. I think it would thrive in the desert. My room humidy is 70% & temperature is 75 deg. F. I'm using compact flourescent 20 hrs. on, 4 hrs. off. The yellow leaf tips happened over the last two days. I don't have any leaf curling or yellowing. My lights were only 6 inches above plants & I just raised them to 16 inches above plants. Please check out this pic & let me know what you think.

    Imo you have the start of nutrient burn. When growing in soil it usually takes two weeks for an issue to show up and two weeks to get rid of it. This issue is not bad at all, and i usually get this with all my grows because i tend to push the nutrients on them in the middle of flower. You really don't need to flush, just back off on the amount of nutrients you are using if you want to clear this up. I usually just ride it out because the rest of the plant looks very healthy and it seems like they love what you are giving them. Not really a big issue. Best of luck to you.  Peace

    I agree completely with harley24. You are at least 2 weeks behind on a problem in soil before it shows up on the plants upper growth. Did this show up before or after you raised the light? I would just do a water only watering next watering Phed at 6.5 and then start feeding the next watering again with a small reduction to the amount of nutrients that you have been using. Might want to feed-water-feed-water-fed if it continues. Some people even feed-water-water-feed. I personally like to feed every watering at smaller levels amount instead of a big heavy feeding. You said you are using organic soil. Are you also using bottled nutrients? If so, I would add 2.5ml per gallon of calmag along with that water only watering. The plant looks great to me to be honest with you! Have fun and please keep us updated as the plant progresses! Happy growing my friend!!

    You have your answer above. It's only a little nute burn. I have it on all of my plants lol. As long as it looks nice and healthy like you have I wouldn't worry about it. Happy growing my friend.

    CFL lights 6 inches away? sounds okay and 20/4 works! just back off your nute strength a bit like everyone said. are you using full strength nutrients?  you can easily get away with half strength nutes and come out smelling like a rose
