Hello, first time grower.
Is this normal? Plant has been slightly yellow tipped on new growth shoots for 10 days. 8 weeks into veg. Water every 3 days, alternate 1/2 strength nutes. Outdoor 6 gallon pot grow in Quality Universal soil with 5%Spaghma Peat and Perlite. Plenty of direct sunshine 10+hrs a day plus a few hrs indirect. Kept it under LED light at night for 6-7 hrs until 10 days ago. Stopped a because of space limitations (getting too big), but may start again soon with lights at night. Sending it into flower in 2 weeks.

Thanks in advance.

it does look like something mild is going on

was the light real close to the tops?

what fertilizer are you using? is it complete, does it have all the micro nutes in it? is it super high in P?
does it have iron?

what are the npk % numbers and the iron amounts listed on the fertilizer and whats it derived from? organic or liquid soluble fertilizers?

theres a few reasons you can get yellowing so its a process of elimination

most common is light bleaching, then theres iron def, then theres iron lock out from excessive P, PH issues could cause it, or possibly manganese issue which is less likely

whatever it is its very mild so don't go doing much until you've talked it thru

doing nothing would be better than doing the wrong thing and or over reacting... its very mild issue if its even an issue at all
its so mild it could be nothing

I don't see yellow tips... Do you mean that it's lighter green in the center? Looks good to me. New growth is always a lighter green

Yes, a bit lighter green which I figured is somewhat normal, but I wanted some feedback and suggestions from actual people. Thanks man

Mine do this every grow when they go into the closet. Bleaching from the lights in my case, yours may be different but looks the same. im4satori knows his stuff bro. Welcome to rollitup. Good luck happy growing

Npk..5.2..5.6..6.4. Organic universal with water soluble and chelated. I'm using separate Cal and Mag supplements since my fertilizer doesn't have any.

Soil ph is 6.2, water is a bit high at 7.4, but it's Italian Alps spring water (it's cheap over here) and I leave the bottles in the sun opened for a few days. to rid it of the chlorine. I was using 2 15 watt LED full spectrum which says equals 50 watts. I
progressively moved the lights closer up to about 16 inches at the end since they weren't having issues with the light. 16 inches for about a week.

I'm definitely not going to do anything drastic. Bump up the strength of fertilizer a bit. I'm at about 1/2 strength.

Thanks for the reply.

Heres a perfect example of sulfer deficiency

If that yellowing progresses you may want to water with epsom salts

I use 1 teaspoon per gallon of soil in each pot
