I personally think she needs more Cal/Mag....these LEDs increase uptake dramatically....so big LED means regular regimen of Cal/Mag....my 2 cents.![]()
Nah not really man..Im not talking about flushing her at all.I just find to stager your doses and feed strengths in conjunction with some run off here dialed in for what your plant(s) is needing at that precise moment and thats is all I ment man.."AFN smoke out"
One of the things that's been hurting him is the fact that his CALMG+ from botanicare is 2-0-0 so there's no way to give them CA and MG without also giving them another N dose.
Doesn't look like N deficiency is the biggest issue to me. The rest of the leaves look nice and dark green, so it looks like (at least at some point in their life) they were getting lots of N. They're still probably getting enough.
Upper leaves going yellow, staying green inbetween the veins = interveinal chlorosis = iron deficiency most likely. Does your Cal / Mag have Iron in it? Can you get Plant Magic Magne-Cal+ where you are? Reason being why I'm saying is that I've been using it and it's been great for me, even with a bit extra N. Also TaNg is using it, so that just double clarifys for me. But him and I are using Advanced Nutrients, however I have seen some killer grows on Dutch Pro nutes too.
So help me out, so I don't have to read the whole thread. You said before
"I've I'm using the Dutch Pro line of nutrients that are specifically designed for autos, and to that I've been adding Botanicare CalMag at 1 ml per litre.
I've been checking, pretty much every day, for any signs of pests, but haven't seen anything. I check both the top side and the under side"
So give me a run down of what medium you are using, how much you've been feeding, what pH you've been running at. Tell me what lights you use etc. Or link me to a post that explains all this already, or just copy and paste it for me
I want to help you out but I need more information.
There's a deficiency / toxicity issue going on and unfortunately it's so far gone and so late into flowering theres nothing we can do now except identity what the problem is and put into remission by stopping whatever you're doing wrong. The plants won't bounce back or repair their leaves. But we can do damage limitation. You'll still get some nice (albeit smaller) buds at the end of this if we sort it out soon.
I really need information on your environment and also your feeding. Specific as possible.
A great product that contains CA, MG, and Iron without any N is unsulphured black strap molasses. You should be able to find it in nearly any town, it's cheap, and it also provides a lot of other benefits like carbs, a bunch of micro nutrients, and feeding any micro life in the soil. If you do pick some up I'd suggest 1 tbsp per gallon to start. You could switch to a three part watering. Watering 1 = feed, Watering 2= molasses, Watering 3=ph'd water.
Okay well that sounds like your problem right there. (a bad start)
Generally if I have a bad start and it doesn't recover by the time I'm into flowering, then well... I kinda finish the grow, hope for the best and learn for next time.
I dunno how to sort your problem out at this stage. Especially as I'm unfamiliar with your medium and nutrients.
I only know how to grow in either
1) Canna Coco Professional Plus + Perlite (60/40 mix)
2) Plagron Light Mix with a touch added Perlite (especially because I grow in autopots)
I would highly suggest using one or the other above. Both very forgiving.
I'm not familiar with FoxFarms soil or Miracle Grow Perlite (except that it's got time release nutes in it.) Possibly the time release perlite is the root of your problem. After having fked up pH and then adding stuff and and making it go too low it's kind of a boomed situation from the get go?
I would flush the crap out of her 40 Litres of tap water and then give her something like 1-2ml per litre A&B and 1ml per litre root tonic and hope for the best.
In my opinion there's really not much else you can do, but hopefully someone else will chime in with better news.
