PH issue or pest/disease or nutrient deficiency?

NY_Gashousestarted grow question 2 years ago

Opened the tent up yesterday and noticed some burning and unusual spots on a few leaves. Plant is 3 weeks old today, I water with nutrients every other day and plain PH water on days I do not water with nutrients. Growing in coco coir, I aim for 6.5 ph water

Grannie doesn't know where she talks about. Your problem is that coco is a hydrophonic medium and for that you need to water the plants with pH 5.8 I would give them pH 5.5 the first time and give double the water that you did before to make the medium more acid. Afther that just give the same amount as you did before already and give pH 5.8 Happy Growing! 😋

There's a lot more information we need in order to try to help you with this.. to ME it looks like there are a couple of things going on - heat stress (leaves curling) and the beginnings of a calcium deficiency - but we need a diary to really tell us what's going on... so go start one and come back to ask your question again please! Good luck

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Brown Spots on Leaves I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Bio Grow burn vs Bio Grow boost Hi, it seems like she keeps getting nute burns as soon as i give her Bio Grow, even at half dosage (1ml/L). She has only 10 more days of veg and i wanted to boost her, what if i stop giving Bio Grow altogether until flowering? Is the tradeoff worth it? No burn but less growing?

Leaves burned after spraying a cocktail To repel aphids I sprayed garlic infused in alcohol with water, already did this few times without side effects. But this time I added several drops of tea tree essential oil. Is it possible that the essential oil has burned the leaves so much or is this some nutrient deficiency?

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should. 1. Are these really signs of nutrient deficiencies? 2. Which nutrients are missing? 2.1. My guess is P, N and/or Mag, Cal. Is that a good guess? 3. Is BioGrow a good choice to address these deficiencies now?
