I’ve noticed a slight lightening of the tips of the fan leaves. It extends up the length of the serrations of the leaves. Just wondering if it’s time to give my girls a flush. I have been a little “generous”.
I did ph to 6.5 with water and molasses last night at 1tsp/gal. I’m in pro mix and they’re at the 16 week mark in the soil.
Any thoughts @MattyBear or any one else.
I do the same with my plants. I feed them until they show slight burn and then I back off slightly with the feedings. I would second what @peachfuzz said and give straight water next time and check your runoff numbers. What nutrients are you using? I know most nutrient lines in Promix want a ph between 5.5-6.2
Thanks @MattyBear@peachfuzz and @Covertgrower. I’m using GH nutes.
Flora bloom and Kool bloom. And black strap. All feeds and waters at 6.4-6.5 ph.
I haven’t run the big container (75l) tote to runoff yet. It gets 4 l every 2-3 days depending on how deep I have to go to feel moisture to the second knuckle. Other one is in 4 gal container and has had runoff.i will measure ph of runoff from that one at lights on in morn.
Don’t have ppm meter.
Thinking the next couple should be just water as well but wanted to be sure first.
@MattyBear. And @peachfuzz. I watered this morn with ph adjusted to 6.4 and runoff was at 5.0.
I’m thinking that’s a bit low. Should it be closer to 6.0-6.2ish. That’s from smaller bucket and I have a few spots on couple leaves from that plant.
Just noticed this morning.
None on other 2 plants in tote. Just aforementioned tips.
This one was almost 3 weeks behind others going into bigger home so was root bound pretty bad.
Thanks for your input.
You want your ph between 5.5-6.2 in Promix. I’d ph at 5.8 because you can cause toxicity or deficiency by feeding outside your medium ph. Basically it will uptake too much of certain nutrients while not allowing others to be uptaken by the roots at all.
@peachfuzz. I have been looking and haven’t seen anything yet today. There’s only 2 leaves affected on that one. I’ll have a look here again just before lights out. Been having a lil issue with humidity running about 28-30 %. Got it up to 53%just about an hour ago and girls are looking better already. Was 34 to start lights on.
I believe that pro-mix has some nutrients in it. I thought about trying it as it is inexpensive and very available, but it is a way off from the Pro-mix HP I normally use. It is a different animal. I have had really great results using it with General Hydroponic nutes.
