This one is day 17 of veg. Its under a 1000w mh. Ive been using general organics grow box for nutes. Doing half of what the box says.
What soil are you using? Are you feeding ferts every watering? I never use ferts for the first 3-4 weeks, I just use happy frog soil. There is enough food in the soil for the first 3 weeks at least. I would stop giving them any ferts and flush the soil with a couple gallons of just water. When you do start giving them ferts again start a 1/4 the normal dose.
The go line is strong. Only use 1/4 of what directions say. If you use full strength you'll probably burn stuff. In my experience to much will give you orange patches on leaves. Just use water next few times then start with lower dose. Also don't mess with ph. The nutes do it for you. You'll lock everything up if you play with ph too much.
Also if you added additional amendments to soil it could throw off ratios in nutes. Cal mag is essential in go line. The others won't work without it.
Also to add on to the blade above me you could throw a little lime in your mix. Just not alot I use a cup for a whole bag of promix. And I'm not going to tell you I'm right. That could be week .
My soil is a mix of peat moss, organic potting soil, blood meal, bone meal, fast start, lime, cow manure compost, and crushed lave rocks. I only used nutes a dew times. I was doing feed, feed, plain water. I flushed them out 2 weeks ago.
Yes i using the grow line. I have to adjust ph because of water. Its at 5.8 to 5.9 when i water/feed. Runoff is at 6.4 to 6.6 I added blood meal, bone meal, fast start to my soil blend.
The space im using is 8' tall, 11' long and 5' wide. I used clf in the seedling stage. About 9 of them in different spec. Im now uaing 2 1000w mh bulbs. Cool air coming in. Hot air going out. Fan blowing under the lights.
Left side of room. Cold air coming it. 1000w mh with fan Right side of room. 1000w mh with hot air leaving this side of room.the bigger plants on this side. Also have a lot of leaves and limbs like this.I added epsom salts.
