Hi there folks, I decide I’d try and reach out to the experts since I’m on my second year outside and having problems again. I’ve grown inside half a dozen times with no issues but outside has been a different story for me. Here’s the scoop, I started 4 plants inside from seed middle of February, they got so big I had to love them into two rooms and they looked fantastic. The strains are all feminized, I have (2) bean sock, (1) blue ice and (1) power Africa XML ultra. I picked them all because they are early strains and my plan was to veg them as big as I can before putting them out for the summer, I need to harvest by late September here. They’re all in promix go and when they moved outside they went from 10gallon to 100 gallon fabrics pots. I’m seeing what looks like deficiencies in all of them but I’ll try to post the pics of the worst one to start. The leaves are almost white in some spots. I’ve checked my ph and I think I’m bang on, I’m feeding with Botanicare grow at about 650ppm at 6.0 and the runoff is 6.1, ppm of the runoff is slightly higher like 850. I also flushed them once with water at 6.0. Ever since I put them outside they haven’t been happy. I’ve attached pics, any help is greatly appreciated. Oh and also my well water which I’ve used successfully indoors is about 250ppm, not sure if there’s any other info you need, let me know!!

looks like phosphorus is locking out.
Bump the ph of your water to 6.5 and if no effect 7.0 . I am imagining the pro mix ph is pretty low. I use sunshine #4
But buffer with oyster shell flour.
Thanks I thought I neede to be at around 6
Ph in promix HP, and I figured my media ph was ok since the runoff is within .1 of the feed going in...?

The white kinda looks like sunburn did you harden them off before you put them out. But certainly deficiencies going on. Those are some very purple stems
Thanks again, I had been using the charts attached and was under the impression that promix hp is soilless and should be treated like hydro hence I’ve been feeding at 6.0. I’ll bump it up and see if that helps. Appreciate the reply very much.

No I didn’t put them out before the move outside, they were so big I could barely get them out the door I guess I should have. That plant has had purple stems the whole way through even inside when it was doing well but there’s definitely something wrong with it. I was wondering if it was sulfur from the charts to be honest. Any suggestions on how to fix? Thanks!

Unfortunately the damage is already done but nothing the plant can’t over come. In the future you want to slowly expose your plants to the suns power. Bring them out the first day and leave in sun for only a couple of hours. Each day increase exposure to the sun. By the end of week they should be able to take full sun full time.
Thanks hopefully they can bounce back.
Appreciate all the replies, I was stumped since nutes and ph seemed ok...
Really eh? Ok thanks I guess I was feeding too low a ph then. There’s a lot of different info on what ph to feed at with promix HP, I’ll lay off till they make a comeback then bump up the ph. Thanks very much.
