Hi please could somebody advice me on what ppm range to stay around at day 27 from germination for example. Week 1 of veg / 150/200ppm or 0.3 ec etc and so on for the weeks ahead as I do not want to burn them and the canna line nutes recommend such high ec early like 1.2 ec for early veg and stuff . I have done my last watering at 350ppm and im sure I can see very faint yellow on the new growth . I am adding co2 tomorrow so don't want sick plants. I have just made a nute mix which is 400ppm and do not know weather to dilute it to bring it down incase it goes to weak for the plants

Look for your Nutes ( feeding chart ) online ... Much easier to adjust from their recommendations than guessing.

Learn how to use your EC/PPM meter to figure out how much or how little to feed them. Start off at 1/8 strength and go from there. Take notes and you'll see a pattern of how they feed during their life cycle.

EC up, too strong. EC down, too weak. EC steady, perfect

I end up at around 2.0 at full maturity in an Aero system. Are you growing in Coco? I usually start at half strength which for me is 1.0 and I've seen deficiencies with plants smaller than your at 1.0, I usually have to move it up to 1.8-2.0 by the time my plants are your size. Faint yellow on new growth indicates not enough food. You have a few Taco Leaves too which indicates high heat or a Mg deficiency. I would be feeding with AT LEAST 1.0. 350PPM is way to low. Also CO2 is going to be a waste until you get your feeding program worked out to a T. What do you have for lighting?
Hi I have 3 X 600w hps and and 1x 600w led and 1x 400 led I am in cocohydro 60/40 mix water once a day with a and b cannazym and rizotonic at 5.8 ph I have been adding 95 ml of a and b ...100ml rhizotonic 150ml cannazym to 50litre bucket but the ec reads over 1 . /(600ppm) So I have been diluting it with water down to 400 or below ppm is this too little?

Half or even a third of the recommended dose usually works for me. OGs can be heavy eaters though.

So if my nutes recommend a total of 1.2 / 1.7 ec which = 600 -850 ppm . Then I can feed half or a third of this? . I have been sticking around 300 ppm but have no clue if is too much or less

Yes. Your plants will tell you. If the tips of the leaves start to turn brown (burn) you are giving them too much. If the leaves are pale, you are not giving them enough. If they are in plastic containers, make sure they are draining well. Cloth pots work the best. Canna hates wet roots.

Your plants look just fine.. not underfed.. Go with the 400 ppm and see how they do.. Slowly increase as the plants get bigger...

OK - I grew RD GTH outside and all of them got PM except the male and a runt female. Be careful.

A year earlier I had a clone of GTH and it was amazing. The runt female RD was very good too.

Thanks, if I water them ever day anyway this will replace fresh nutes everyday so the food should be available to them 24/7 shouldn't it?

Are they fed all at once or do you use a drip system?

Do they sit in a tray of water or does it all drain away?

Im guessing pm is mold? The breeder says they are not prone to mould but my rh is always 45 0/0 so I added two cool misters which now make it 55 0/0 rh but I checked a moment ago and it was 61 0/0 for the first time in three weeks
