Khalmenacestarted grow question 4 years ago
This plant is on week 6 or week 2 of flower. I have watered at ph of 6.2-6.5 from the start but my runoff is coming out at 4.5-5ph. Also wondering if this is whats causing the leaves to show rust spots that getting worse. Does anyone know how to fix this?

stop watering with "buffered" water just water with regular old tap water and you soil which I am guessing is Peat Moss based will lower the ph of your water.. When you add nutrients in the formula as well it lowers the ph as well. So just water with regular old ph 7 tap water and let your nutrients and soil lower the ph.... Often people overcomplicate growing. We are only allowing them to grow we aren't making them grow. What I mean is Cannabis plants grow despite what growers do not because of it.

You will have nutrient lockout if it's that low. Phosphorus/potassium etc are absorbed best when the pH of the substrate is just over 6 (more in soil I think )
If your in soil maybe water with extra volume of water until the pH rasies back up to the correct level .

Why dont my plants grow towards the middle/light and instead concentrate near the walls?Looks like my plants are growing towards the wall and not towards the middle where the light should be the best.
Why do the plants behave like that and what should I do?
Raise the net, rotate some of the plants, then redo the net?
Remove the net completely?
leave it as it is?

What do you guys think?It's my first grow (automatic, 6 weeks old) and compared to other plants, my plant looks a bit small/ridiculous. I give her 24/7 light (I read that on guides) is that maybe too much? What's your impression of her? I use two growlights (one from above and one from the side).

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

¿Por qué no se desarrollan lateralmente?Tengo algunas teorías:
1) Exceso de riego (por problemas varios, he tenido que regar 1 vez por semana en gran cantidad (demasiado)
2) Estres por movimiento (debido a tormentas y otras razones, muevo las plantas de ubicación varias veces por semana
3) Exceso de fertilizantes?

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.
