Set auto system for VPD or RHI have AC Infinity set up. I am wondering whether I should have the humidity triggers set up for VPD or continue with RH triggers. So far I have it triggered when humidity gets a tad low. If I trigger for VPD, I think I will have to constantly check leaf temp. Thoughts?

Iron deficiency?This A.M I treated her with a cal-mag mix due to yellow leaves. Today the leaf showing symptoms "tacoed" a little bit and the tip curled upwards. Same symptom on a few other leaves but only on the tips. Iron deficiency perhaps? PH'd soil on 3 spots: 6.6, 6.18, 6.3. What to do????

Yellow discoloration againI'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

When is a good time to start pruning?When is a good time to start pruning? She is about 10 inches tall and is short and VERY bushy. Has several leaves hidden from light and so I am thinking of pruning today. However I don't want to do it too soon. So far my pruning has been VERY minimal. Thoughts?

"dunking" fabric pots in solution for feeding?I have recently been presented with the concept of "dipping": submerging fabric pot in solution for about 8 seconds and then picking up to drain. It is intriguing to me but I am curious about it causing overwatering or root rot. Thoughts?

Light burn2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

Water and nutrientsI water every other day. So far I have been using nutrients to bring my water up to the proper EC (ppm). It is always a VERY small amount (1/2 tsp). I haven't noticed any signs of toxicity but I wanted to hear your opinion of my approach and changes that I could/should make

Why does my bottom leaf have brownish white tip and is cripsy?Was checking leaf temps all over and at the very bottom first 3 point fan leaf that she ever grew I noticed the center leaf crispy at the tip with some light green spots around it. The only other leaves that look like this are the single first true leaves. Thoughts?

Possible toxicity or deficiency?I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

Found something weird on my new leaves. Need an expert's opinionFound something weird on my leaves. I need an expert's opinion and insight. I don't know if it's natural to occur on newly developing leaves or if it's an issue that needs to be addressed. I'm thinking it might be natural but it seems weird to me.

Grow light questionI notice a decent drop off in PAR as my meter moves away from center. I have a 2x2 tent and am thinking of buying a light for a 3x3 tent that has gaps allowing for ventilation. Any thoughts?

Watering with tap waterI have partially filled a bucket with tap water and put some air stones in there to circulate and aerate the water. I will leave it for over 24 hours to evaporate the chlorine but how long is too long?

Leaf issues. More specific questionAsking again but I'll be more specific: I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/brown color along the sides of 1 of the true leaves leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Damping off? Thoughts?

What should my VPD be for a grand daddy Purple seedling that hasn't developed its cotyledons yet? Currently am hovering around 0.8 to 0.95. Temp around 75/76 F and RH around 68/69%. As far as I understand it, GDP seedlings need the RH to be between 60 and 70 %.
