I am getting yellowing leaves mostly on the tips and on the edges of my upper leaves.The plants are in 5 Gal. buckets and are approx. 2' high. I water them both with approx. 1/2 gal. each per watering. using 2 tsp. ( 10 ml) of PURE BLEND PRO in the watering . Although using nutrients only once per week. Yesterday I watered them and now today when I stick my fingers 2" or so into the soil it feels dry.
Erm only 2 things that spring to mind are, are they to close to ur lights if ur growin under lights and have u growen this strain of plant before? cud it just b the strain of plant?? r they in flower or veg at the moment?
like barnaby said.....possibly heat stress....what light and what's the distance to the plants.....are they all showing signs of this?......it's most likely overfert......if i were you, i'd flush the medium with fresh till it comes out the bottom and then wait a day or 2.....you'll see a diffrence.....Peace out.....Sid
Thanx, I was using just a 150 HPS, I added a 175 HD. I had to re-arrange my grow space. The HPS was in the back approx. 14 in from the top of one plant....this height has been the same for about 1 1/2 weeks. The HD I just put in was approx. 16-18 in from the other plant. I have as of yesterday, moved the HD up quite a bit and I am now going to move the HPS. Note: mainly the front plant that was under the HD was affected, although the one under the HPS had a little yellowing on the side that was closest to the HD. Most all of the yellowing was at the top 1/4 0f the plant and most all of the yellowing involved just the tips. No I have never grown this strain before......Thease are my first. I would like to show pictures but everytime I try to upload it never seems to work......( canyou help me with that?
makesure the filename ends like XXXXX.jpg, or .gif or whatever, just makesure that it has a . and file extension jpg or gif So it should look like mypicture.jpg yourpicture.gif Hope that helps, CWL
