Co2/Temps/Nutrients
I pushed the temps up and got the VDP on point w/co2. Now since the plant is drawing a lot more water up through the roots, I've noticed very slight nute burn on the newest leaf growths. Do you have to drop PPM's as temps rise? I thought it was the other way around?

Tâches sur feuilles ??
Bonjour, je commence a avoir des tâches sur certaines de mes feuilles qui séche. Est ce que ça vient de ma lampe led qui est trop près des plantes ? Ou est ce que c'est un surdosage root juice ? Dites moi s'il vous plaît. Merci à vous.

How do you harvest in hydro (drip system with a tank) when some are late ?
Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...

brown tips on some leaves
first week of flower, only one plant out of five affected, only couple of leaves close to the top affected (up to 5 in total) - my assumption is 1. too close to light (I have 40cm between 400HPS which seems enough), PH problem or deficiency (potassium?)

Please look at last picture - there is an area of crispy brown on the lowest leaves of the Red Diesel. I'm thinking it's a little bit of light burn, but am not sure. Any thoughts from any of the experts?

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

I think underwatering combined with the light being close has caused my issue. However older leaves have also dried up and died (but staying green). The way the leaf looks with yellowing though, and because a couple of leaf stems are turning reddish, maybe it's K deficiency?

Cal mag or nutrient Burn
I have 3 Automatics. I made the mistake of planting the into BioBizz Allmix, which is pretty strong for Autos. Strawberry Gorilla and Aplle Strudel seem to be fine. My Orange sherbet not so much. Is this Cal/ Mag defficiency or nutrient burn?

Yellowing edges and brown tips in 7 week of flower.
Hello, fellow growers. Need some help. I'm in 7th week of flowering and upper leaves start yellow with burnt edges. The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?

I've been having this problem with the browning leaves on the bottom. 1. Every time i do DWC from seed, the picture as shown on Week#2 Day#11 happens. Why is that? 2. What do you think is causing the browned lower leaves? Is it calcium deficiency? Or potassium?
