But the amount of Calmg needed depends on the concentration of the product right? The ones available for me are Canna Mono which is 14% Calcium and 7% Magnesium. Going with 1ml/Gal seems quit a lot for me. Which product do you use? Ahh and one import info. I am growing hydroponics

High Guys Having my second run with autopots ATM using Biotabs(supersoil like pills containing various meals npk 15 7 8 and some guano) in a 50/50 peat moss perlite mix with some coco thrown in. The Biotabs should provide nutrients for the whole run what they perfectly did in the last one but...

I treated them with a product against Thrips which leaves an oily residue but is not harming the plant... Used it alot before. I am talking about the black leaf tips which I've never seen before ;( Thanks for you reply guys Hope somebody has seen it before ;)

High Guys I am running a autopot grow with Biotabs 50/50 perlite peat under a 315w CMH bulb. I had several runs with this setup always performing decent but this time I got the molding leafs tips you can see on the pictures. Any idea what's going on? I have seen several deficencys and diseases...

I've reduced to EC 1.0 and they are doing fine now. But you are right it's probably K but because of to much fertilizer. EC 3 would be killing them straight away....

Which media are you using? Hempy as well? Ph 7.5 sounds way to high if you don't have a buffering peat substrat

Depends on where in the Box it is between 500-680umol 3500k Guess everything up to 800 should be fine? I start with RO water 0.0 EC go up with CalMg to 0.2 and then add Maxibloom till I reach 1.2(that's what I do now before till 1.6)

Why do you think I defoliated to much? It was really full in there and my intention was to get a better light penetration. This girl is drinking a lot I give her 10l every 3 days and try to keep the topsoil moist ;) And yeah I know I will stop giving any fertilizer for at least 2 weeks now and...

I always thought everybody is using hempy bucket drain to waste style. But hey Always ready to learn new. Any recommendation on how many pots I should use per 1m2? Will try several plants in the next run ;)

This explains the multiple day feed. Ok just for my calculation How much medium would you recommend for a 1qm space? Like I know more plants=smaller pots but how much perlite in total? 30l for 1m2 is fine? And I made an mistake Not used to calculations in gal. My pot is around 8 gal ;) Sorry

Yea it is :) But my plant is nearly 1qm so I guess a huge bucket is needed?

Was always watering till 30 % runoff so hopefully no salt buildup Your advice: flush and feeding EC around 1.0 afterwards? Multiple feeds a day? Ive read a lot about hempy and throught you should the hempy let dry a bit between the waterings. Maybe watering every other day. Now you say...
