Getting out of the ideas - VPD, nutrients or deficiency?I'm getting out of the ideas as the foliar symptoms proceed.
Lowered EC down to 1.8 from 2.2, pH in range.
VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24CLeaves. Edges burnt

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?3y ago

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?6y ago

Leaves burnHi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips.
I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!Leaves. Edges burnt

I found out my tap water was 9.8. I'm about to water tomorrow with PH adjusted water, I just didn't know whether or not that could be the issue with the tips turning yellow? Bigger plant now too,just not as bad Basically will the soil adjust since it's a premix in between 6.3-6.8Week 3

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?Leaves. Tips - Burnt

Plant getting lighter — deficiency or excess?Plant getting lighter overall. Thought it was N deficiency. Since N is mobile, expect older leaves to fade first. But its more the top/whole plant. Using Floragard Grow Mix w/ Greenhouse Feeding Bio Grow (1/3 dose due to pre-fertilized soil). Bloom fertilizer was added yesterday.7mo ago

low pH problemsI discovered that I had irrigated with water at pH 3.5 for at least 5 days.
yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?6y ago
