Whilst the plant doesn't look unhealthy- the growth is really slow. Any ideas? It's been 20 days from potting now. Is my Phone at 7-8 to high and having a massive affect? I'm using Coco coir.
Ph at 7 is too high. Aim for 6.2 in veg in coco coir and 6.5 in flower. She looks like she has a nitrogen deficiency starting and that'll be a ph lockout. Day air temp could creep up a bit to 80f or a little higher if you have good air movement (night is fine). Humidity at 41% is very low so think about trying to up that with wet towels / humidifier. What you have not told us is substrate temp or solution temp. These need to be 72-74 as lower will cool the roots and slow growth. Just a few tweaks and she'll be fine.
After lowering the pH I've had better success. I bought a pH down solution, which unfortunately got lost in the post. I've been using small amounts of white wine vinegar instead.
Only thing is, I'm struggling to maintain pH at 6.2-6.5 through watering every few days. Any ideas?
I topped it about 10 days ago. Growth in general has really stunted. Please please please can someone tell me what the white stuff on my leaves are?
The whole plant is looking affected and I don't know what to do. :'(
I have white spots on my leaves 8 ball leaves.. I also have a wonder woman growing which is going yellow at the tips. I'm struggling to keep the pH down, is this it? Should I just water every day to keep it down? I'm worried about over watering.
Weird leaves problems? If your pH is out of range, then it's most definitely the cause of it. Why are you having so much trouble keeping the pH down? either use a pH down solution or apple vinegar if you are into more organic nutes. Also 0,5 liters seem a like too much for a plant that size, try 0,3 liter, that should last it 5 to 7 days.
Morning,
So at first glance my instant thought was light burn, as I had a plant display a similar white/yellow spotting. If your ph is 6.5 there's nothing wrong with that for soil growing, it can go up to 6.8 and still be safe. You dont seem to be giving a surplus of nutrients to burn the plant with. But you are using HID which is very powerful and hot. All your stats look good, my one possible suggestion is raise the light to 24inches and lower your hours to 18.
Also plants thrive on having a wet period and a dry period, the dry encourages the plant and its roots to seek out water, aka more growth longer roots etc. I wouldn't water excessively if I were you, it wont solve any ph problem that I know of.
Best of luck, plants are truly resilient, I dont doubt she'll be ok, just needs some adjustments. ✌️🌱
Right now u have major ph and overwatering issues plus calmag #1 u need voodoo juice are a good root booster let her dry out a few days get a ph meter and a ppm meter its like having a gun with no bullets🤔🤔🤔 get fox farm big bloom this will fix your plant and its organic u should have mixed perlite with your lite mix all these problems is caused by your roots if u get your roots right this plant will turn around in a week your ph should be at 5.6 5.9 she is very stressed give her wat she needs she will shake back 👍👍🍻🍻
