Hello all, I got thoses clones from my brother 3 weeks ago, and they were about 1/3 of the size they are now. My brother is notoriously an heavy feeder and he was always giving them about 1700ppm or more of ghe nutes WITHOUT any problem. I give them 1500ppm each watering. Since you guys always 2/3 of the nutes I do specify it. They were turned 12/12 and transplanted 5 days ago.

I didn't change yet my feeding schedule of the ghe trio, (3ml/l of 5-0-1, 3ml/l of 2-1-6 and 1.5ml/l of 0-5-4), + enzymes and a little rhizotonic xp. I grow in promix BX

I have a bluelab pulse meter, and the ec in the pots of the plants with yellow tips was only 1.5, while all others pots were at 2ec. I have two mixed strain. I don't know wich are wich but I suspect the plants with yellow tips are the other strain..

Of course, when I add my nutes my solution PH is lowered to a perfect level, and I have a bluelab soil ph tester wich tested my soil to be at a ph of 6.0.

Picture of another plant without symptoms: 20220331_031108.jpg20220331_031501.jpg20220331_031054.jpg

I grow in a 3x3 with 440w of leds, air intake and air outtake. 2 clips fans. I raised the light yesterday in case it was light burn, but new growth looks problematic I think..

May I also add that I always freak out when comes watering time? I'm never sure if they are dry enough, and ready to water. I'm afraid of overwatering and also underwatering lol. At each watering I give them a good liter each every 2-3 days. they are in 2 gal pots, and 3 gal smartpots

Suggest you learn to water by weight. A 2 gallon bag should be able to take 2-2.5 liters of fluid.

So I should get a little runoff when I water is that what you said? because 2 liters definitely get almost completely absorbed(I tried it) And 2.5 liter get me half a liter of runoff.. BTW thanks for your help really appreciated!

I'm still trying to learn by weight lol, so I should completely saturate the medium even tough it's promix bx and not hp? I didn't had promix hp on hand

You want your medium to be wet thoroughly. Not dripping water but thoroughly saturated. Yes even with BX. Next time you transplant and before adding water to the medium pick it up.

Repeatedly. Then water with at least 25% of the container volume. A 5 gallon container should be able to take 1-1/2 gallons of water. If it can’t without dripping aerate the medium thoroughly throughout the entire container top to the very bottom. Especially under the plant.

Water slowly around the container about halfway between the stem and the side of the container. Allow it to soak in well before adding the rest. Do this weekly and when you dump the container out you’ll find it’s a solid mass of fine roots and comes out in one piece. After watering in the first water pick it up. You don’t want to let it get as light as it was at transplant. But you want to get close.

The strains with the yellow tips are more sensitive than the others. I've had different phenos of the same strain
need different feed.

Just tested runoff ppm to be at 2400, maybe I watered too early and that's the additional nutes from last watering, but I will water them at 1300ppm from now on instead of 1500-1600

And I also think I have to change the ratio of micro veg and bloom, my ratio of bloom nutrient to veg and micro was way off I think?
