Those plants are looking good. I really think I could fit the 250HPS in the space I have but I must stay under 200w total so that leaves me with about 185w for lights, I will be adding the second light soon. This is only my second grow so I hope it goes well. So far I have had several problems with nute deff and mites. Always something new every round. Keep up the good work you will be growing trees in no time.

I'm trying, lol... seems like I am constantly either doing something with the Cab to help them or checkin up on them. Your first grow I was very impressed with, 40g with 1 plant and for how small that bitch was.. very nice. Must have been a lot of training, looked all tidy n clean lol. Are your 70watters the same as mine? You should post a pic of your setup- I would like to see how you mounted yours and just how your setup is...
If your having probs with Nute deficiencies this chart may help. You might already have it or something like it but it has helped me so far and if not help you too.. maybe someone else roaming around this thread.
pH Nutrient Uptake Chart for marijuana
Also, the Link I am about to post you may already have or atleast something similar but.... I`ll post anyways. This link will explain each Nutrient deficiency and show pictures of each. Coupled with this chart, you should be able to diagnose/correct any problems.
Marijuana Plant Abuse
Those are amazing pictures man. I'm also very interested in your grow!
I will be following you to completion!
Thanks man- One reason I am interested in how your plants react to the MH is because I am thinking about setting my small nightstand up as the veg cabby and was thinking of throwing a 70w MH bulb up in it. I have used Mercury Vapor before but in my opinion the plants stretched a little more. From what I heard the MH helps keep them small n bushy.
Day 13 - pH 5.7 - 235 ppm - Temp 75 - RH 40%
Plants are still doing good. I got my PPM meter today in the mail so I will be updating in the format above from now on. I took the reading of the PPM and my nutes were at 180 ppm. Because of the burns from a few days ago, I am a little worried to add too much even though 180 is a little low. I want to get it up to 400 ppm within the next few days. If there are no Nute burns tomorrow when I get home, I will up it too 300 ppm. By Friday, I should be at 400 ppm for sure. I will let that run for a couple days before I increase again with a res change. More Pics Tomorow.
