Brown spots on lower leaves - ph fluctuations?
NeoCatstarted grow question 4 years ago
I have discovered some brown spots on the lower leaves.
I suspect it might be down to ph fluctuations - first time growing DWC so probably my bad!
Does anyone agree?
I should also add - I did a nutrient change a few days ago and for the first time added calmag & silicon

Hi mate, you're absolutely right. This is due to PH. It really depends on the kind of water you have used. Tap water ions react with nutrients and ph adjusters to raise or lower the ph. I started using deionised water for this reason and have seen great results because of it. Reverse osmosis water works too. You clearly know what you're doing so keep up the green work, good luck and happy growing

Thanks @sir_isO & @BraveheartGenetics, much appreciated!
Will monitor the situation and reduce nutes if necessary.
I've started looking into RO systems now š³ This setup has cost me so much! Sure it'll be worth it though š

The calmag should help, particularly calcium.
Other than that it seems like it's slightly overfed in terms of nitro.

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Overwatered cubes in hydro? Too close to the sun? or effect of having addHi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes.
Did i manage to overwater some of these plants by having them too close to the net pot?9 months ago
