Sick plant(s). Could use some info please.

[byronthemad]

Some sick plants here. I believe its PH but i cannot be sure since i cant decide which color the litmus paper is lol. I know they tend to yellow late flower, but this seems early. I recently got a new place(the country) so its somewhat new to me. Ive grown this ww for a year+ on 60 day cycles. I couldnt believe it being due to the heavy feeding, but idk lol. There is some burn tho as you can see on the tips. Youd think i know my plant better xD


Hi heres my pics. Linked to my album since idk another way

Any info?

1. Get ph in check.

2. If you are using gh 3 part you MUST mix the micro in the water FIRST.

3. You should be using hard water micro if your water is over 200 ppm.

4. I use the recipe below, it is called the useless formula, works in hydro and soil and uses the GH 3 part nutes.

OK, I figured I would post this here, since some folks are asking about the GH 3 part.
This is my feed schedule -

Here is the nutrient regimen I use and how I control PH with little or no ph up or down...

So OK - feeding schedule week by week. This is the GH weekly feeding program, slightly tweaked. I will only call out the volume of each part per gallon of water in the following manner: grow, micro, bloom, ppm range. Example - 5-2.5-2.5-400/800 would mean 5 ml grow, 2.5 ml micro, 2.5 ml bloom and a ppm of 400-880. Remember it's per gallon. You Euro's can easily convert to liters. 4 liters is just a little bit over 1 gallon. It should also be noted that I use the hardwater micro due to my tapwater. I suggest using the hardwater micro in place of the regular micro if your tap water is over 200 ppm total or you have over 70 ppm Ca. RO water users should use the regular micro.
Veg -
week 1 5-2.5-2.5-400/600
week 2 10-5-3- 600/800
week 3 12-6-3 800/1000 (continue week 3 formula if additional veg time is required.)

Bloom
week 1 6-6-10- 800/1200
week 2 3-7-12 - 1000/1400
week 3 3-8-14 - 1000/1400
week 4 3-8-16 - 1000/1400
week 5 (discussed in detail below*)
week 6 0-7-20 - 1000/1400
week 7 0-6-20 (see below**)
* During week 5 if not using a booster like Superbud, Bushmaster Kabloom etc. run 2.5-7-18. I use MOAB (Mother of All Blooms) or BushMaster at 50% of recommended strength, and use 1.25-3.5-9 for the fert base.
**If running an 8 week strain you should only run the ferts during week 7 for a maximum of 3-4 days. This gives you 10 days for flushing. I should note that if I use ferts for a few days in week 7, I take the plants over the 8 week mark. Personally I flush for a min of 14 days. But 10 is bare minimum imo/ime.

The ppms work out almost exactly. I tend to lean toward the lower side of the range, unless I have a really heavy feeder that I know can handle it.

At every ressy change out I add in 5 drops per gallon of 35% food grade H2O2. During flush use ph adjusted water at 5.5-6.0
I will add epsom salt at week 1 of bloom if the plants are heavy feeders AND I see signs of an Mg def. Otherwise I won't use it. The only time I have ever had Mg def is during transition. The GH 3 part is a little low on Mg, but the PBP and Canna nutes are way lower.

Now- how to control your PH...
There are a couple factors that cause your PH to drift. The most common is running the nute solution too strong or too weak. If it's too strong, your PH drops. If it's too weak the PH rises. You have to find the balance point. If you find that the formula above is say, a little strong, and say you have a 20 gallon ressy, mix the nutes for 18 gallons. If it's a little weak, mix it for 22 gallons. You follow?
The other common mistake is mixing your nutrient solution and trying to adjust the PH right away. You have to allow time for the ph buffers in the nutrient solution to do their job. Mix the nutes up, and bubble or circulate for 12 hours before even looking at your PH. You will find the PH to be almost right on target.
I use little or no ph adjusters. (Except during flush). I use tap water, with a starting PPM of 300-400 and a starting PH of 7.4-9.0 (Thats crazy you say! The water is too hard, you will never get stable PH and you will have too much Ca, causing a lockout of Mg!) Bollocks I say.
Every week, on Friday I drain the ressy and fill with plain water. I let that run overnight giving the plants a little flush. This also allows the chlorine and ammonia to evap. On Saturday morning, I mix the nutes into the ressy. I DO NOT adjust ph at this time. Let that run as is overnight. On Sunday morning, I check ph and adjust if needed. Usually don't have to.
Doing things this way has saved me from constant PH drifts, and using about 150 ml of ph down every ressy change, and a little here and there throughout the week to keep it in the desired range. Now, the most I ever have to use is about 30 ml.if any at all. (I have a 35 gallon ressy btw) My Ph stays at a constant 5.5-5.8.

If you are still having PH issues using the above method, an alternative is to PH adjust the plain water to 5.5 BEFORE you add nutes.

Thanks. Very informative. I will try your recomended feedin schedule. I will def be getting my ph in check. The litmus paper is damn hard to read imo. OR maybe im just colorblind lol. Ill jsut buy a cheap pen. Testing runoff i suppose.

I have a new place(medical grower) and the water is junk apparently. Iron smelling, staining toilet nastyness. Well water to say the least.

just looking at your pics i would say either over nutes, over watered, or root problems like pythium...


i am presently going through a pythium problem spread by a bad tea i made, organic fertilizer and fungus gnats...the bad tea introduced the bad bacteria, the organic nutes helped feed the bad fungi and the gnats spread it from plant to plant.

anyways some of my plants look like yours, the random defs are from the bad roots not being able to take in all the plant needs...


im not saying you have pythium root rot, but the plants look exactly like what mine do once the infection is pretty bad...next phase would be the stems getting weak and in bad cases the plant falling over due to the roots being so weak they are unable to support the plant

I couldnt imagine it being overfeeding. These widows are REALLY hardy plants(lemon skunks are perfect). I started the *intense* feeding schedule roughly 2 weeks ago. (I had given them 50% strength nuts 2,maybe 3, times before the agressive bloom twice a week for 2 weeks prior) I fed @ 100% every other water. Id say it was roughly 4 or 5 agressive feedings. Now i havent fed in 3-4 days now.

As well if over watering. They dry out pretty quick in there. They are typically dry as hell if i skip a day of watering. Sometimes* they dont need it everyday tho and i dont water.

ROOT ISSUES. I know nothing of this problem. : / I will have to look into this.

I appreciate all the info you guys/gals have posted. I will be taking all your comments into consideration and deal with each problem as you have suggested.

Very unfortunate to hear about your root rot fresh. As far as the weak stems. I usaully support them anyways. I figure this being then end of week 4 its about due

Thanks guys. And btw this is the most advanced marijuana forum on the net that i have found. Im glad to be a part now.

the reason why i said over feeding is because the miracle grow soil contains slow release ferts, and if you are adding ferts on top of that then you could lock out certain minerals or swing the ph low by over feeding and building uop too much salts in the medium, just remember what the plant doesnt eat will be left in the soil

how often are you feeding? are you feeding every time you water?

I didnt feed the plant at all until about 2 weeks into flower(a month+old). I hit them @ 50% GH recomended twice in a week. Few days later i hit them full str every other water for 10 -12 days. Thats about 5 aggresive feedings id say. They havent been fed now in 4 days.
