Lets try again... This is Blueberry strain growing in a 3'x3'x6.5' grow tent using 900 watts of Mars Hydro LED's. I am using entire Foxfarm line with Foxfarm OF soil in 5 gallon pots. They will be in flower for 3 weeks on the 5th of this month. I tried posting both pics, sorry about the sideways one. I use about 1/2 of what the feeding chart says to use as I was recommended to do. My fan leaves just under the buds are turning this redish purple color on the edges and curling down. Can anyone help me out on what I am doing wrong? Im thinking it might be a "P" deficiency but I am unsure. Any help would be much appreciated.

I water faithfully at 6.5 PH.
Never heard of too much light... Maybe add some CO2 to the tent?
The temp at the top of my plants is about 78 degrees F and about 72 at the bottom. I open top of tent while lights are on.
I checked my runoff on last watering and was 6.1 PH
I also water till about 20-30% runoff.

Doubt too much light since it's a Mars. Usually they are about half of the stated wattage. What nutes?How much? And the pH definitely can be an issue.

Thought I would dust off an oldie and pass it along. Not sure exactly how relevant it is.

Nutes: All measurements are per gallon.
*Big Bloom 7.5ml
Big Grow 5ml
*Tiger Bloom 5ml
*Flower Kiss 10ml per gallon foliar spray 2x week
*Boomerang 2.5ml
*Kangaroots 1ml
Microbe Brew 1ml
Bembe 7.5ml
*Kelp me kelp You 5ml
*Open Sesame 1/8 tsp
Beastie Bloomz 1/8 tsp
Cha Ching 1/8 tsp
*Cal/Mag 10ml
Im in week 2 flower so im using the ones with stars by them currently and starting week 3 tomorrow. Watering at PH 6.5 with a runoff of 6.1.
Whats your guys opinion on what and how much nutes I should use in my next watering?

Phosphorous deficiency.Your pH sounds proper. Add a dilute feed of your veg nutes. They need some N to help take up other nutes. Cut the other nutes because it is late stage and is caused usually by the solution having to high an EC/PPM. Any idea what the EC/PPM is of your water and then of your feeds?Or are you mixing them from the label directions?

better pic still under grow lights taken just now.

Unfortunately I don't have a ppm tester and I'm just going by label as best I can. Only thing I have is a PH meter.
Ok so this means this EC/PPM meter is a must? One question im sure to have after buying one is... How do I raise/lower EC and PMM to get the correct levels I need? I can add the nutes and stuff to the mix and PH it correctly but did not know anything about EC/PMM till just reading about it. Sounds pretty important.

You need a PPM meter.

At the rates you say
*Big Bloom 7.5ml
*Tiger Bloom 5ml
*Flower Kiss 10ml per gallon foliar spray 2x week
*Boomerang 2.5ml
*Kangaroots 1ml
*Kelp me kelp You 5ml
*Open Sesame .5 ml
*Cal/Mag 10ml
Total 41.5ml
I bet you have a PPM over 3,000 at that rate. All those nutes are likely locking each other out at that rate. I would recommend you simplify your nutrients and measure your final mix to ensure you stay below 1600 PPM.
Do you use RO/Distilled water? If not, stop using Cal/Mag, it is likely your lockout cause.

I use this same line up...my ph runs 7.0. Did you transplant with OF right before flower cycle? Have you followed the feeding chart since wk1?

what are your temps when the lights are off? blue and purple strains start to change color with lower nite temps, just like the leaves on the trees outside in fall..esp late in flower

I transplanted into FFOF when plant gets about 1 foot tall and let veg for 45 days or so then switch to 12-12.
Yes I feed by the schedule but only about 1/2 of what they say to use.

Id try raising the ph to 7 and giving recommended dose. Are you feeding 1 or 2x a week?

You need a EC/ppm meter to measure your nutes. Not to mention OF is pretty hot as it is, so adding nutes all the time w/ OF I'll bet your EC is off the charts. When soil dries, nutrients dry too and stay in the soil (what is not used by the plant). When you water again, it hydrates the left over nutes, if you are adding nutes every time, I would not be surprised to see your ppm runoff very high. If it were me, I would run straight ph'd water with no nutes for awhile. Heck, depending on the runoff ppm/ec, I might flush them until the runoff is somewhat normal.

I would use pH test strips before I went without a EC/PPM meter. Hanna makes very good units for the money. You don't need to spend for a Blue Labs unit.Unfortunately I don't have a ppm tester and I'm just going by label as best I can. Only thing I have is a PH meter.

I have PH test trips but I don't use them because they suck compared to the PH meter I have. Never once did I say I did not have a PH meter.
