Plants were growing superb until I had to move them around the house to fumigate, paint and set up the grow room which is already good to go. I had 3 plants ready to flower that's gone sick. They're showing Chlorosis on the newer growth or growing tips. In overall she had a week of stress from changing environments, I expected some estretching, dark leaves and bruned tips as possible consequences adding to the fact fumigation gasses could hurt them despite I kept them Isolated and the younger plants are not showing any signs out of the expected. I can't set up my mind on what this signs on the upper leaves could be. My soil's been good all around and I supplement a little calmag as well which they've liked all the time. So please take a look and tell me what you see Fe, K?. I'm gonna post pictures of the SLH mostly and a Moby Dick that's showing same symptoms, there's also an LSD

On new growth I always check what has happened about the last 3 days before I noticed it . Like feeding , watering or anything else that is recent the plants may have been exosed to . Sorry I can't be of more help , I have a lot to learn myself . At least most of the color looks very good still .

Well So I narrowed it down to Iron and Sulfur. I'm gonna flush with super thrive and check my nutes for add some GH micro to the mix. Hope they bounce back. I don't have a PH soil taster I've been told that measuring run off wont work. Any other handy quick method?

Well this happens when Soil Ph is two low (under 4) mine is 6.7 so a def of potassium should be the cause, too less K, you lock out Iron ... I did the flush wrong as I used superthrive, Sweet and Calmag on the mix, a good combo of micros and enzymes but I left out K, so I'll have to foliar feed and pray (this is my 420 smoke). Diluted Flora Bloom or Kool Bloom could work as I was checking on the labels. I'm adding some in my next feeding.. hope they make it till then.
