What kind of deficiency?
We are in the middle of week 6. I think there is a deficiency or a toxicity. I couldn't understand why. Could you please check?

I'm not experience in growing and this is my first plant. I'm still worried by the yellows of young shoots. Can someone help me recognize the problem ? 🙏 All suggestions will be valuable. 👍

Leaves yellowing
These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

250 PPM? - Week 6 - Autoflower - GH Trio
Fresh res. New growth (cola pic) leaves are scorched a bit. Result of tox from 2+ weeks ago, still hot? My PH/PPM equilibrium is 250pmm w/ 0ppm H20. If I follow this rule (I never done), she would max out in 350ish PPM. Anyone follow the dance thru harvest? GH Trio nutes.

problems with clones!
Friends, tell me what's wrong with the plant! I don't understand it's under-feeding or over-feeding! At first I thought it was a cal-mag deficiency, then I saw a purple stem and thought it was a phosphorus deficiency! Now I don't know what it is anymore! at the very beginning it

Can this delay flowering of an auto?
What deficiency is this please? I suspect phosphorus deficiency and as such have reduced the PH from 6.4 back down to 5.8 It is not spreading and appeared spontaniously and at once a few days ago. Growth has been slow for almost 2 weeks and flowering has refused to initiate.

Nutrient burn or deficiency?
I’m seeing brown spots that resemble a calcium deficiency but I’m feeding them cal mag:s One of the tips on the new growth looks burnt so it looks like i may be feeding too much or immobile deficiency? I’m feeding about a 500 ppm of newts. Any help is greatly appreciated.

PH all kinds of fucked up!
Urgent update. So it turns out the issues all alone where the soil ph which after testing it was PH 3.2 😳 I have flushed with ph 6.8 water and then added some epson salts bringing the final ph back to 5.6-6.2. I then topped the pot with new fresh compost. Will she survive?

Why is this deficiency or toxicity spreading so fast!?
Had a light case of what was believed to be calcium deficiency. Ph, EC and ppm all seemed normal for run off and I've halved my nutes but kept a higher dose of CalMag going. Didn't water them last night now it looks even worse, what should I do and will the end product be ruined?

What is causing PK deficiency signs on mid leaves? Too little Calcium causing lockout??
Hey everyone, in mid and late flowering with my autos, all experiencing similar problems and I’m inclined to believe it could be due to a lack of Calcium? Could a Ca deficient plant cause these symptoms which resemble a PK deficiency?? I’m 100% adding enough bloom

Nute lock or nute deficiancy?
had some yellow leaves start to pop up on one of the girls. Looks like a nute lock that we will address with a PH water flush and then slowly wrk them back up onto the feeding schedule. Didn't check my Ph and my guess is Ph went too high in the soil.. Thoughts from my gurus?😇
