Cannabis Troubleshooting

Hey Im trying to find a way to take preventative measures in protecting my plants from mold. Now ive read up on what to do when you have mold and the need for airflow etc. But im more talking about sestemic sprays with short holding periods to use 2-3 weeks into flower when they are just starting to bud up. I have an indica dominant that i grow in my tent, i keep things clean as i can with good airflow but i still suffer from mold every time at about week 8 if im lucky and not earlyer. Does anyone have a recommendation? Thanx in advance

I only noticed this the other day. The branch nodes have this weird looking....I don't know what you would call it......Looks like she has been lifting weights. This is only apparent on the Red Devil F4 both pheno's. The photo variety of the same generation doesn't have it, well it does but it's hardly noticeable. Anyone else had this happen before?

Howdy all, This is my first grow so lots to learn but so far I haven't been able to pin down what's wrong with one of the plants I'm growing. Basically the leaves are a mottled colour with patches of yellow in them. The leaves also don't look smooth. I'm growing 2 other strains that are not showing any problems.

I started to give very weak nute solution …

Hey guys, looks like I've hit a road block. Done a lot of searching and still got really get a straight answer. Some say P is low, some say N is low, some say the salts are too high, some say it is normal.... Who is right? Basically the plants were doing fine in the DWC until about a week ago when a few nute problems started to appear. It was yellowing veins in the leaves, this has now spread over 2 plants and I'm thinking they may need to bed pulled or will die.
