These are my Cazberries after about 3 and a half weeks of growth in Vermisoil under a 1000 watt metal halide conversion bulb. they were given foxfarm grow big and ph down as well as verm tea... these girls grew great until they showed yellow tips (starting at the very tip of the growing points and working its way from the center of the leaf blade to the tips). It looked like a sulfur deficiency to me so i gave them a good dose of foxfarm grow big, they showed a little greening at the center of the apical tips, but by this point they were too damaged and i scrapped them for some blue dream cuts. these blue dream cuts were in rockwool (the cazberries were in 4 inch soil pots) and they showed the same yellowing after only 3 days! i believe it may be my soil (vermisoil) due to the fact that the cazberries that were in 4 inch pots took a little longer than the blue dreams. I am using well water but there is chlorine in it. Has anyone seen an extreme yellowing like this? (other than N deficiency)

I've had that happen twice in my life. Once was rootbound. Other a tiny increase in Phosphorus solved. Damaged growth never recovered. New growth was fine.

the ones in the pics were transplanted about three weeks before from 4 inch to two gallon (definitely werent root bound) and the blue dreams im dealing with now were rockwool cubes that were just planted into their 2 gallon containers. i gave them a mild dose of grow big which has plenty of phosphorus for the young plants, and the yellowing showed up VERY fast on both crops (even thought the cazberries took 3 weeks to begin showing probem)

thanks for the help, but ive had a lot of experience dealing with nutrient problems, and this one seems to be much different than what ive seen... the extremely yellow tips that show up pretty much overnight are like nothing ive experienced. especially because the blue dreams were only in my garden for a few days days and they were in rockwool before that.doesnt seem like enough time for a nutrient deficiency to occur

If you know there is chlorine in your water and you suggest chlorosis, why not start there? Cant one bubble a reservoir to remove chlorine? or are there other rememdies?

Chlorine and Chlorosis don't really have much to do with each other than the "Chlor-".

I have tried two different soils (foxfarm and vermisoil), two different water sources (spring vs tap), and two different nutrients (foxfarm, sugar peak, and no nutrients at all) and the plants all yellow after about three or four days in the room... my pH is 6.5 and im running out of ideas... PLEASE HELP, i see no reason why these plants should yellow so quickly

Tell us about this room. This room versus other room.
Temps day and night.
I assume second room is flower & first veg?
Your in soil but adding nutes?

For hydro nutes pH is lower.

Perhaps your locking out uptake with pH or too much phosphorus.

Four feet high is way far for the light. 20" from canopy is better if heat isn't an issue. See if lowering the light helps.
